NIST welcomes students from all over the world to apply to our school, and applications are accepted for review throughout the year. However, we strongly believe that selecting a school for your child is one of the most important decisions you can make, and one that deserves careful consideration. Before submitting an application, we highly encourage parents to visit our school by arranging to meet one of our admissions team and touring our campus. All applications must be submitted through the online application form. Also note that if you are currently living in Bangkok at the time of application, the deadline for submission is 16 December.

If you believe that your family will be a good match for the NIST community, you can complete the application process in five steps. Please review each step individually and ensure that you understand it in its entirety.


Step 1: Gather the Necessary Documents & Information

Completing the online application form is only possible when you have prepared electronic copies of the following documents. The specific format for each is specified below, and must be uploaded as attachments when applying. Please note that Thai nationals should also submit a copy of your child’s Thai birth certificate.

If you are unsure of which the year level you should select for your child when you apply, consult our age/year level equivalents, which show how the NIST year levels correspond to differing ages and national curricula.

Year 12 Applicant Information 

The Year 12 Application Information form must be completed and uploaded with the online application for year 12 applicants so we know which subjects you are interested in studying.

Recommendation Form: Y1-Y6 or Y7-Y13or EY Parent & Teacher QuestionnairesOnly the form for the year to which your child is applying needs to be completed by your child's current teacher. Multiple forms can be completed. This form can only be accepted directly from the school completing the form, and can be sent after the online application is submitted.
Medical InformationThe student medical form must be completed and uploaded with the online application. The immunization record can be uploaded to the online application or submitted at the time of enrollment.
School RecordsMust include the current school year report cards (to date) and the previous school year report cards (for elementary school applicants) or the previous two school year report cards (for secondary school applicants). Copies of any standardized achievement results (e.g., IOWA, PSAT, MAPS, ISA, etc.) should also be submitted. All of these documents must be in PDF format.
Additional Records (if applicable)Any documentation relating to special services your child is receiving or has received in the past. This may include IEPs/ISPs, educational or psychological evaluations, speech and language reports, OT reports, etc. (PDF or DOC).
Passport ScansCopies of the passports for each applicant and his/her parent(s) (PDF or JPEG).
Digital PhotosOne high quality passport-sized digital photo for each applicant and his/her parent(s) (JPEG: 120 x 160 pixels). Please do not upload the scan of your passport in the photo section. Here is an example with appropriate size and placement.
Legal DocumentsFor foreign applicants, a copy of the Thai visa of each family member and work permit if applicable. (PDF or JPEG) We understand that this may follow at a later date.

Step 2: Complete the Online Application Form

All applications to NIST must be submitted through our online application form. We do not accept paper applications. Please check that you have prepared all of the necessary documents from Step 1 before beginning the process.

Step 3: Application Review by Admissions Committee

Our admissions committee will review the application in accordance with the school’s admissions criteria. The length of this process varies depending on the time of year at which you apply, and factors taken into account about each applicant include:

  • Age
  • Class size/space availability
  • English language proficiency
  • Previous school records and recommendation(s)
  • Siblings currently at NIST and alumni siblings
  • IB programme experience
  • Nationality/ethnicity
  • Admissions test/academic ability
  • Extra-curricular/community involvement
  • Parent employment with the United Nations

After making a candidate’s records and application, the admissions committee may then grant approval for an admissions assessment. The school reserves the right to not accept an application if the student is unlikely to be accepted to NIST. In other cases children may be invited for an interview and assessment in order to help to determine their educational abilities and possible needs such as English as an Additional Language (EAL) assistance or other specialized support.

Step 4: Admissions Assessment

After completing the above steps, candidates may be invited to sit for an admissions assessment. All elementary school assessments take place at the NIST campus. In certain circumstances, the NIST Admissions Office can arrange for the secondary school assessment to be taken at the applicant’s current school. All candidates must pay the testing fee of 2,500 baht, which is non-refundable, regardless of entry to the school.

After reviewing the assessment results and school records, the school will make a final decision as to whether or not the child may be enrolled at NIST. Please note that the admissions assessment material is private and is considered to be the property of the school; parents will not be entitled to the original or a copy.

Step 5: Enrollment

Families will be notified as soon as possible of the admissions decisions. After this notification and the submission of all documents requested by the school, the actual enrollment take place. Once a place has been offered, the family has a limited period, specified by the school, in which to accept it. At the time of acceptance to the school, certain fees are payable. This will be explained in further detail by the admissions staff.

Admission to the school does not guarantee student enrollment beyond the initial year, which will be dependent on the maintenance of satisfactory levels of progress and behaviour, as well as space availability. Class placement is determined by NIST in order to guarantee a balance of several factors, and individual requests unfortunately cannot be accommodated.

Families who choose to accept an offer of enrollment may prepare for the transition by reviewing the information in Starting at NIST. Those arriving in Bangkok from overseas may also want to look through the resources provided in Moving to Bangkok.
