Admissions Process

As a parent, choosing the right school for your child is one of the most significant decisions you will make, and we understand the concerns, worries, and hopes that come with it. Our international community in Bangkok is large and dynamic, and we are honored that you are considering KIS for your child's education. We extend a warm welcome to new students and provide support for their smooth transition to KIS, with admissions accepted throughout the year.

KIS uses OpenApply, an online application portal, which allows us to streamline all inquiries, visits, assessments and applications. You will be asked to create an account with your email address and a password. Please use the same details to log in each time.

Please use Grade Listing & Comparison to see when your child can start at KIS International School or which grade they would be eligible for on the button below. Additionally, we have an alternate admissions procedure specifically for Early Years applications. Please click the button below if you are interested in Early Years.

Step 3 : Assessment 

The assessments serves to determine how a child will cope with the transition into the new classroom environment and whether or not we expect the child to be able to access the programme at that particular grade level.

The assessment consists of the following elements:

Early Years Prep - Early Years 3
  • Classroom Observation 
  • Parent Interview

  • Family interview
  • Thai assessment for Thai students

Families will be notified about the admissions outcome within 1-2 weeks after review of the assessment test results, the interview, and the consideration of the admissions criteria. Once a place has been offered, the family will be given a specific time to confirm the acceptance in writing to ensure a seat for the prospective student.

Step 4 : Registration

Once the family confirms the placement and settles all payments, the student will be enrolled and provided with an ID number. KIS will then request the necessary items to complete the registration process.
