International School Admissions in Thailand
Applications, assessments, waiting lists, school places, entry requirements and the decisions that matter before your child starts.
How admissions really work in Thailand
There is no single nationwide application system for international schools. Each school sets its own entry policy, calendar, assessment requirements, fees and capacity. Even schools offering the same curriculum can handle admissions very differently. Some assess applicants during fixed windows before the next academic year; others review applications on a rolling basis when places are available. A school may accept one sibling immediately while another must wait for a vacancy in a different year group.
For most families the process involves an initial enquiry, a school visit or online conversation, an application with records and identification, an age-appropriate assessment, a decision and finally the payment and paperwork needed to secure the place. But the sequence matters: some schools will not assess a child until the application fee has been paid; others may advise families to check availability or submit records before making a formal application.
It is useful to distinguish three different outcomes: eligible to apply means the school will consider your child; offered a place means the school has accepted them subject to stated conditions; and enrolled means the offer has been accepted, required payments and paperwork have been completed, and a start date has been confirmed. Do not treat a positive tour or encouraging email as a guaranteed place.
Shortlist three to five realistic schools through the International Schools Hub, then ask each admissions team whether there is a place in your child's exact year group for your proposed start date. A school having places generally does not mean it has one for your child.
When should you apply?
For a planned relocation, starting nine to twelve months ahead gives families more options, particularly for sought-after schools and secondary year groups. It is not a universal deadline: some schools will process a suitable application much faster, while others have formal annual windows. Some schools advise applying about a year ahead, while others review applications throughout the year or work to their own annual deadlines. The actual timetable must always be confirmed with the school.
These are planning milestones, not school-mandated deadlines. If you are moving in six weeks rather than six months, contact schools immediately and ask about rolling admission and available assessment dates. A complete, well-organised application often helps avoid preventable delays, but it cannot create a place where none exists.
Research curricula, locations and likely fees. Shortlist schools, check entry-year availability and arrange visits or video calls.
Request application requirements. Collect reports, passports and recommendations. Ask about assessments and learning support.
Submit complete applications, attend assessments, compare written offers and clarify deadlines for deposits and fees.
Confirm enrolment, visa responsibilities, transport, uniforms, devices, medical records and orientation arrangements.
Review your child's adjustment, teacher feedback, friendship groups and any additional language or learning support.
The international school application process
Build a realistic shortlist
Start with curriculum, your child's age, likely commuting distance, fees and learning needs. Consider where you may move next: a child returning to the UK, United States or another country may benefit from continuity in curriculum and examinations. Use the JLIT International Schools Hub to compare schools before contacting them.
Ask about the specific vacancy
Give the child's date of birth, current school year, curriculum, intended start date and relevant support requirements. Ask whether the school is accepting applications, assessing for a waiting list, or able to offer an actual place. If siblings are applying, ask about every year group separately.
Tour and question the school
Visit during an ordinary teaching day if possible. Ask to see the classrooms your child would use, not only the headline facilities. Meet someone who can explain teaching, language support, safeguarding, pastoral care and how newcomers settle. Families abroad can request virtual meetings or tours, but should clarify which assessments require attendance.
Submit the application and records
Complete the school's own portal or form, upload requested documentation and pay only the fees you understand. Be consistent about the child's legal name, date of birth and educational history. If a document is missing, ask whether the application can be reviewed provisionally and when the final copy must arrive.
Attend assessments and interviews
Expect the format to change by age and school. Early years may involve observation and play; older students may sit English, mathematics or cognitive assessments. Parents or children may also be interviewed. Ask whether assessment can be conducted online or at the child's current school.
Receive and review the decision
A school may offer a place, offer a conditional place, place the child on a waiting list, suggest another year group or decline the application. Request written clarification of any conditions, required support programmes and deadlines.
Secure the place and prepare to start
Check the acceptance letter, payment schedule, refund rules, withdrawal notice period, visa documentation and start date. Complete medical and emergency-contact forms, arrange transport and uniforms, and ask for an orientation plan. Keep copies of every payment receipt and written agreement. For relocation paperwork, also consult the JLIT Visas & Immigration Hub.
What documents will parents need?
Requirements vary, but the following checklist covers documents commonly requested by international schools. Some schools need certified translations into English; others accept scans initially and originals later. Check the exact list before spending money on certification or translation.
Disclose learning needs and relevant support documentation accurately. The purpose is to establish whether the school can support the child effectively, not simply to pass an admissions test. If you are concerned about how sensitive records are handled, ask who reviews them, how they are stored and whether an initial confidential discussion can take place before a full application.
Identity and family
- Child's passport and, where requested, birth certificate
- Parent or guardian passport copies
- Current Thai visa or immigration information, if applicable
- Recent photograph of the child
- Custody, guardianship or parental consent documents when relevant
- Thai identification or house-registration documents for applicable families
Education and support
- Recent school reports, usually one or two years
- Transcripts or examination results for older students
- Teacher or school recommendations where requested
- Existing learning-support plans and specialist reports
- English-language or other assessment results, if available
- Attendance, behaviour or school-transfer records if requested
Health and administration
- Vaccination or immunisation records
- Medical information and allergy details
- Emergency contacts and authorised collection contacts
- Application and assessment payment receipts
- Relevant visa or residence documents requested for enrolment
- Any additional school-specific consent forms
Save one clearly labelled PDF folder per child, with readable filenames and English translations where necessary. A missing report or recommendation can delay an otherwise suitable application, particularly when assessment slots are limited.
Entrance tests, interviews and school readiness
Admissions assessment is not one standard examination across Thailand. A school's aim may be to establish academic readiness, English proficiency, the support a child needs, or whether a particular programme is an appropriate fit. Some schools are academically selective; others place more weight on whether they can provide suitable teaching and support.
| Age or stage | Common assessment methods | What parents should ask |
|---|---|---|
| Nursery / early years | Play, classroom observation, developmental readiness and a parent conversation | Is a trial session required? What independence skills are expected? |
| Early primary | Classroom activities, literacy and numeracy checks, language observation | Is this a placement assessment or a selective entrance test? |
| Later primary | English, mathematics, writing, cognitive tests and sometimes a class trial | How are students with limited English assessed fairly? |
| Lower secondary | Academic records, English and mathematics tests, interviews and reasoning assessments | Are subject placements or additional support required? |
| IGCSE, A-Level or IB years | Subject records, programme prerequisites, interviews and sometimes subject-specific testing | Can the school offer the exact subjects and graduation pathway needed? |
For example, Bangkok Prep publishes different assessment arrangements by age, including readiness sessions for younger children and cognitive, English and written tasks for older applicants. KIS Bangkok similarly describes classroom observation for early years and more formal mathematics and English assessments for older pupils. These are examples, not requirements at every school.
How should a child prepare?
Preparation should focus on confidence and familiarity rather than pressure. Explain who they will meet, what the visit might involve and that the school is trying to understand how they learn. For younger children, a good night's sleep, an ordinary breakfast and reassurance are more useful than last-minute drilling. For older students, review recent schoolwork and ask the admissions team whether any sample material or guidance is available. Never assume a test result alone determines admission.
English as an Additional Language (EAL)
Children who speak another language at home may be capable students while still needing English-language support. Ask whether the school offers EAL, whether support is included in tuition, how it is delivered, and whether there are minimum language expectations for a particular year group. At secondary level, limited English can affect access to demanding subject content, so a realistic transition plan is essential.
Learning differences and additional needs
If a child has dyslexia, ADHD, autism, a disability, a speech-language need or another learning difference, discuss their actual support needs early and confidentially. Ask about specialist staff, classroom accommodations, assessment adjustments, therapy arrangements and any additional charges. A school may have a learning-support department but limited capacity in a specific year group. Ask for a written explanation of what it can and cannot provide before committing.
Age cut-offs, year groups and curriculum transfers
A child's year-group label does not necessarily transfer directly from one education system to another. British schools typically use Reception and Year 1 onward, American schools use Kindergarten and Grades, and IB schools may describe programme stages differently. Age cut-off dates also vary. The same child can be placed differently depending on their birthday, prior school system and the receiving school's policy.
Transfers become particularly sensitive around IGCSE, A-Level and IB Diploma programmes. Courses may run over two academic years, subject combinations may not match, and examination boards or coursework requirements may differ. A school may decline mid-course entry even when it has physical classroom capacity. Shrewsbury Bangkok, for instance, says joining partway through IGCSE and A-Level programmes is possible only in exceptional circumstances.
Do not simply write “Year 6” on an application without explaining which country and curriculum it refers to. Provide the child's date of birth, last completed school year, expected next year and current subjects. Ask for the receiving school's age-placement chart and whether placement is based primarily on age, prior attainment or both.
Waiting lists, siblings and conditional offers
A waiting list is not an offer of admission. Schools may manage lists by application date, year-group capacity, sibling status, programme fit, language profile, nationality mix or other published criteria. Policies differ, and a family's position may change as other applicants accept or decline offers. Do not assume the list is strictly first-come, first-served.
Ask whether your child has been assessed and found eligible, whether the school has a current or projected vacancy, how often the list is reviewed, whether you must renew the application, and whether the application or assessment fee is refundable if no place opens. Some schools do not assess applicants when a year group already has a long waiting list; KIS Bangkok explicitly notes this in its published process.
If you have two or more children, ask what happens if only one is offered a place. A sibling preference is not necessarily a guarantee, and two separate commutes or school calendars can become a major family burden. Consider a realistic backup school for all children rather than treating a preferred school as certain.
If you're waitlisted
- Ask what the list status actually means
- Confirm whether the assessment remains valid
- Request the next update date
- Keep a second school application active
- Check whether any paid fees are refundable
If you're offered a place
- Get the offer and conditions in writing
- Confirm the exact year group and start date
- Check the deadline to accept
- Verify the deposit and withdrawal rules
- Ask when enrolment is formally secured
Can children join halfway through the school year?
Often yes, but not always. Some schools admit throughout the year where space and suitable support are available. Others work around term or semester starts, assessment windows or programme restrictions. For a family arriving in October, January or April, the first question is not simply “Do you accept mid-year applications?” but “Can my child join this exact year group on this date, and what teaching will they have missed?”
Ask how the school assesses gaps in learning, whether it provides a settling-in buddy, whether transport and extracurricular activities are available immediately, and whether the child will receive a full or prorated term invoice. For secondary students, request a subject-by-subject transition review. A school that can admit a student administratively may still be unable to offer their desired examination subjects.
Families transferring from a Thai school, a home-school programme or a non-English-language system should bring detailed records and be ready to explain what has been studied. The admissions team may ask for additional assessment to place the child appropriately. Avoid presenting curriculum differences as a failure by the child; they are a planning issue to resolve with the receiving school.
Application fees, assessments, deposits and enrolment charges
The amount shown as annual tuition is rarely the total cost of securing a place. A family may pay an application fee, assessment fee, registration or enrolment fee, refundable or non-refundable deposit, advance tuition, transport charges and uniform or technology costs. Terminology varies by school, so request a full written fee schedule for your child's year group and entry date.
| Charge | What it generally covers | Check before paying |
|---|---|---|
| Application fee | Processing and reviewing the application | Is it refundable if the child is not offered a place? |
| Assessment fee | Testing, observation or admissions evaluation | Is it separate from the application fee? |
| Registration / enrolment | Confirming a new student's entry | Is it one-off, recurring or transferable to another campus? |
| Deposit / capital fee | Security or school-specific development charge | Exactly when and under what conditions is it refunded? |
| Tuition | Teaching for a term, semester or academic year | What are the due dates, increases and late-payment terms? |
| Additional services | Transport, meals, EAL, support, exams, trips or devices | Which are compulsory and which are optional? |
Published fees illustrate how much policies differ: for 2026–27, Shrewsbury Bangkok lists a non-refundable application fee of THB 5,000 per child, and International School Bangkok an application fee of THB 4,700. These are school-specific examples, not standard Thailand rates; always confirm the current schedule and campus.
Before accepting an offer, calculate the cash required before the first day, not just the annual tuition. Ask whether fees are prorated for a mid-year start, how much notice is needed before withdrawal, and whether deposits are returned if a family must leave Thailand unexpectedly. For a detailed breakdown, see International School Fees in Thailand.
Visas, guardianship and moving to Thailand
School admission and immigration permission are separate processes. A place at an international school does not automatically grant a child or parent the right to live in Thailand. Depending on nationality, age and the family's circumstances, a child may be in Thailand as a dependent of a parent, or may need an education-related immigration route. A parent may also need to consider their own appropriate status. The school can usually explain what supporting letters it can issue, but immigration requirements should be verified with the relevant Thai authorities or consulate before travel.
If only one parent is relocating, or the child will live with another guardian, check custody documents, school authorisations, emergency contacts and immigration requirements early. Families should also plan housing and transport around the school journey: a manageable commute can make a significant difference to a child's adjustment, especially in Bangkok traffic.
Ask admissions whether the school provides enrolment letters, when these are issued, whether full payment is required first, and what it needs from a parent or legal guardian. Clarify whether a child must already have a particular visa at the time of application, assessment or enrolment. Some schools have different application streams depending on passport and visa circumstances, so ask which applies to your child.
An admissions officer can explain school documentation, but cannot guarantee an immigration outcome. Verify current visa requirements independently before making non-refundable relocation commitments.
Settling in after admission
Acceptance is only the start. Children may be excited, anxious or both, especially when they are leaving friends, familiar routines and perhaps their first language behind. Ask the school how it welcomes new arrivals, introduces classmates, monitors wellbeing and communicates with parents in the first term.
For younger pupils, find out whether a phased start or settling-in session is available. For older students, ask about tutor groups, house systems, subject catch-up, extracurricular clubs and friendship support. If the child is joining mid-year, check how missed units are handled and whether there is a named member of staff to coordinate the transition.
Parents should establish a communication routine without treating every difficult day as a sign the school is wrong. Agree on a sensible early review point with the class teacher or pastoral lead. If there are concerns about bullying, anxiety, language access or additional support, raise them promptly and ask what specific follow-up will happen.

International school admissions: frequently asked questions
Can foreigners enrol children in international schools in Thailand?
Yes. International schools serve expatriate, Thai and other international families, subject to each school's admissions policy, capacity and applicable requirements. Nationality and visa status may affect the application route at a particular school.
Can Thai children attend international schools?
Many international schools admit Thai children, but the applicable admissions process and any regulatory or school-specific requirements should be confirmed directly. Some schools operate different application timelines for Thai and international applicants.
Do children have to speak fluent English?
Not necessarily. Some schools provide EAL support, while others expect a particular standard of English for a given year group or examination programme. Ask how the school assesses language ability and whether it can support your child.
Is an entrance exam compulsory?
Not at every school or age. Assessment might involve classroom observation, interviews, language or academic testing, or a combination. The exact requirements are set by the school.
Will an application fee guarantee a place?
No. Schools may charge for application processing or assessment even when a place is not offered. Confirm refund terms in writing before paying.
Can I apply to several schools at once?
Usually yes, subject to each school's procedures. Multiple applications can protect against a waiting list, but they may involve several non-refundable fees. Keep track of decision and deposit deadlines.
Can my child start in January?
Possibly. Some schools consider mid-year admissions if the appropriate year group has space and the curriculum transition is manageable. Ask about term dates, assessment availability and fee proration.
What if my child has additional learning needs?
Contact the admissions and learning-support teams before applying. Provide relevant documentation and request a clear explanation of the support available, capacity, accommodations and any extra fees.
How long does the admissions process take?
There is no universal timescale. A school with rolling admissions and an available place may move relatively quickly; another may review applications over months or require assessment in a fixed window. Ask for an estimated timetable based on your child's year group.
Should we choose a home before the school?
Where possible, shortlist and investigate schools first. The school commute can shape daily family life and may be particularly demanding in Bangkok. Avoid committing to a location before checking realistic journey times.
Changing curriculum: what admissions will check
When a child moves from one curriculum to another, the admissions team has to decide two things: which year group they join, and which courses they can realistically continue. The questions differ by curriculum. For how each curriculum is structured, the qualifications it leads to and how universities treat them, see our full guide to international school curricula in Thailand.
Joining a British-curriculum school
Year groups are set by date of birth, but a pupil joining Year 10, Year 11 or sixth form is entering a two-year IGCSE or A-level course, so subject choice can be limited. Ask the school to confirm in writing which exam subjects, and which exam board, your child can continue.
Joining an American-curriculum school
For Grades 9–12, ask for a written credit audit before you accept a place: which previous courses count, what is still needed to graduate, and whether your child can graduate on time. Check how the school calculates GPA and which AP courses a new student can join.
Joining an IB school
Confirm the school is authorised for the programme your child needs. Joining during the two-year Diploma Programme is difficult: the receiving school needs to compare Higher and Standard Level subjects, completed internal assessments and predicted grades before it agrees a transfer.
Joining a Cambridge school
Compare exact syllabuses, not just qualification names: a Pearson Edexcel IGCSE and a Cambridge IGCSE in the same subject are different courses. Ask which subjects, exam sessions and exam-centre arrangements apply to a pupil joining mid-course.
Moving from or to a Thai or bilingual school
Bring detailed reports and translations, and expect a diagnostic placement discussion rather than a direct year-for-year match — Prathom and Mathayom grades do not map exactly onto British years or US grades. See international vs bilingual vs Thai schools for how the systems compare.
For any secondary-age transfer, get the year group and the subjects your child can take confirmed in writing before you pay a deposit.
Fees, deposits and everyday costs
Admissions is where the money starts: an application fee when you apply, and a registration or guaranteed-place fee and deposit when you accept a place. The full picture — published 2026–27 tuition for example schools, one-off charges, deposits, refunds, transport, uniforms and meals — is in our guide to international school fees in Thailand.
Tuition

Application process: what happens at every stage
Start with a targeted enquiry rather than submitting multiple incomplete forms. Tell the school the child’s full date of birth, current year group, current curriculum, intended start date, nationality and relevant language or support needs. Ask whether there is a realistic vacancy in the exact year group before paying a fee.
Schools may require passports, birth certificates, recent reports, teacher recommendations, attendance records, vaccination information, photographs and evidence of a parent or guardian’s status. Some also request standardised assessment results or confidential references sent directly from the previous school. Requirements can differ for Thai and international applicants.
| Stage | Family action | Proof to retain |
|---|---|---|
| Enquiry | Confirm vacancy and curriculum fit | Admissions email |
| Application | Submit documents and fee | Receipt and submission confirmation |
| Assessment | Attend tests/interview | Assessment schedule |
| Offer | Review conditions and deadline | Written offer |
| Enrolment | Pay required sums and complete forms | Enrolment confirmation |
After submitting the application, families may be invited to an interview, school visit, trial day, online assessment or academic testing. An admissions officer may ask for further reports or specialist documentation. Respond promptly, but do not interpret an assessment invitation as an offer of a place.
The decision may be an unconditional offer, conditional offer, waiting-list position or refusal. Conditional offers might depend on English-language support, final reports, a successful assessment or the availability of an appropriate programme. Read every condition and confirm the deadline for accepting.
Only after the school has issued a written offer and you have accepted its terms should you treat the place as secured. Ask what payment or document completes enrolment and whether a late payment causes the offer to lapse. Keep copies of every email and receipt.
What parents should check
- Check year-group availability before paying.
- Submit complete, consistent documents in the format requested.
- Confirm the assessment date and decision timeline.
- Get conditions, deposits and start date in writing.
Use one tracking sheet for every school: application status, fees paid, next action, offer deadline and contact person.
Waiting lists, oversubscription and entry requirements
A waiting list does not necessarily operate as a simple first-come, first-served queue. Schools may consider year-group capacity, the balance of existing classes, learning-support resources, language proficiency, sibling policies and other published admissions priorities. Ask how the school defines its list and whether it can disclose a meaningful estimate of your chances.
Distinguish between a child who has passed assessment but is waiting for a vacancy and a child whose application has not yet been assessed. A place on a list is not a promise that the school will offer admission by a particular date. If the family must move by a fixed deadline, keep a realistic second choice active.
Entry requirements can involve age cutoffs, prior attainment, English-language ability, school reports, attendance history and the capacity to meet documented learning needs. These should be assessed according to each school’s published policy. Families should ask what support is available rather than concealing learning or language requirements that will affect the child’s experience.
For siblings, check each year group independently. One child may receive an offer while another remains on a waiting list. Ask whether the school has a sibling policy, whether offers must be accepted together and what happens to deposits if only one place materialises.
For examination years, a vacancy may still be unsuitable if the pupil cannot join the required subjects or complete assessment components. Ask the academic head to review the proposed transfer, not just the admissions office.
What parents should check
- Does “waiting list” mean assessed and eligible, or merely registered interest?
- Are there published priorities or expiry dates?
- Can the family keep an application active for a later term?
- What happens if siblings receive different outcomes?
Do not commit to a home or surrender another school place on the strength of a waiting-list email.
School visits, interviews and assessments by age
A campus tour is a chance to examine everyday teaching, not merely sports facilities or a polished reception area. Ask to see a typical classroom, the library, lunch arrangements and the areas used by your child’s age group. If possible, visit while classes are in session and speak to someone who can discuss curriculum, support and pastoral care.
Early-years admissions may use observation, play, interaction with adults and basic developmental activities rather than formal written tests. Primary-age pupils may be assessed in reading, writing, mathematics and English-language ability. Older students may take subject-specific tests, cognitive assessments or interviews about their previous studies and intended examination subjects.
| Age/stage | Common assessment approach | Parent question |
|---|---|---|
| Early years | Play and developmental observation | How is readiness judged? |
| Primary | Reading, numeracy, classroom tasks | What language support is available? |
| Lower secondary | English, maths, interview, reports | How are subject levels decided? |
| Exam years | Subject prerequisites and prior syllabus | Can the course be completed? |
Assessment is not always a pass/fail event. Schools may use results to determine year placement, language support or whether the child can access the curriculum with available resources. Ask what happens after the assessment, whether feedback is shared and whether a reassessment is possible.
Parents should prepare children by explaining what the visit is for, ensuring they are rested and providing familiar schoolwork when requested. Intensive coaching for a school-specific test may give a misleading picture of what the child can comfortably manage every day. Honest discussion of strengths and support needs usually serves the child better.
During a tour, observe student interaction, behaviour expectations, class sizes and communication with parents. Ask how new arrivals are welcomed, what happens when a child struggles and how concerns about bullying or wellbeing are escalated.
What parents should check
- What assessment will my child complete at this age?
- Can the school assess from overseas?
- Who explains the results and placement recommendation?
- Can we see an ordinary lesson and talk to the relevant year leader?
A school tour should help you judge how your child will learn and settle, not just whether the campus looks impressive.
