Admissions Process

Whether you live in Croatia or will be relocating to Zagreb from another country, we recognize the importance of finding the right education setting for your family. We are here to help.

Application Timeline 2021-22

AISZ has a rolling admission policy for the current school year - which means that students can be admitted throughout the year for Pre-Kindergarten to Grade 10, assuming availability in these classes. In Grades 11 and 12, we encourage families to contact the Admissions office as soon as they consider applying to AISZ to have a discussion about potential enrolment.

Because we have limited capacity for each grade level, the school will select students best-suited to maximise the AISZ experience.

Current enrollment for the 2021-22 school year by section:

  • Lower School
    • Pre-Kindergarten and grades 1-5 – available seats. 
    • Kindergarten is at full capacity.
  • Middle School
    • Grades 6-8 – available seats.
  • High School – Enrolment is particularly competitive and seats are in high demand. We are encouraging entry into middle school grades as an advantage.
    • Grades 9-10 – available seats.
    • Grades 11-12 – available seats, however please contact the Admissions office as soon as possible if you are considering enrolment in these grades for the 2021-22 school year.

If an applicant is accepted but no seats are available in the appropriate class, they will be placed on a waiting list and families will be asked to confirm the placement on the waiting list. If a seat becomes available in the appropriate class, the place may be offered to a student on the waiting list. Acceptance on the waiting list is for one academic year and may require further documentation before admittance into subsequent school years. We will contact families towards the end of the academic year to confirm their status.


Application Timeline 2022-23

For the 2022-23 school year, an application can be submitted at any point in time. All complete applications will be reviewed within the following time frames:

  1. Early Admission - Applications submitted by December 1st, 2021, will be reviewed and families informed of next steps on December 15th.* The main goal of this deadline is to review applications from families relocating to Croatia and for students who do not speak the Croatian language. *Applications may be deferred and placed on a waiting list until a later date if determined by the Admissions committee.
  2. Regular Admission – Applications submitted by March 30th, 2022 will be reviewed and families will be informed of next steps on April 13th. The main goal of this deadline is to review applications from all families relocating/living in Croatia and for students attending a local Croatian school.
  3. Rolling Admission – After April 1st, all complete applications will be reviewed on an individual basis. The Admissions office strives to complete the application process and notify families of next steps within ten business days of the application completion date. Please note that the time span for application review during school holidays might take up to four weeks. Rolling admission will be possible from April 2022 to March 2023.


Important note for families relocating to Zagreb: Families should not disenroll their child/ren from their current school until they have been accepted at AISZ. Completing an application does not guarantee admission.

Meet our Admissions Manager

Martina joined the AISZ community in 2017 where she worked with families across the school in an administrative role. After discovering her passion for supporting families who are in transition – moving to Zagreb, joining new schools, perhaps even moving to an entirely new country - she was promoted to admissions manager in 2021.

Born and raised in Zagreb, Martina enjoys meeting people from different cultures and communities, and learning about their lives and experiences. She believes that students benefit immensely from being part of an international, multicultural, and diverse community, and she’s committed to helping families make the right choice for their children’s education. Martina’s favorite thing about AISZ is seeing students’ smiling faces as they enter school each day. Martina is multi-lingual and speaks English and Croatian, and she is currently working toward becoming fluent in German. Her favorite way to spend her free time is with her family; as an animal person that includes a number of cats and dogs.

Martina would welcome the opportunity to meet your children and your family, and she invites you to reach out by email or phone to schedule a tour of the school campus and/or a video call. She is here to answer your questions and guide you through the application process at AISZ. She has found that these introductory meetings can be very informative and often help reduce anxiety and stress that can be associated with a family’s transfer to a new location. In addition, all families are encouraged to explore the AISZ website to learn more about the school, its academic and extracurricular programs, and to take a walk on the AISZ campus through this virtual tour.

The first step in this process is to complete the above form. After logging in to our platform, a one-time payment of a non-refundable Application Fee is required after which you may begin the online application process. Applications are reviewed only if the application is completed in full and submitted through the portal.

Application Checklist

Fully completed applications must include (but are not limited to):

  • Last two years of report cards (a certified English copy)
  • Official Transcripts (for HS students)
  • Two medical forms (downloadable from the online application portal)

All documents must be translated into English with certified copies submitted to the school.

Application Priorities

AISZ follows a priority system in line with its Admission Guidelines, which are:

  • Priority 1: Dependents of employees of the United States Embassy of Croatia and their associated Diplomatic Missions, and eligible dependents of AISZ faculty.
  • Priority 2: Expatriate or host country students transferring from an international posting who do not yet have a school in Zagreb.
  • Priority 3: Expatriate or host country students transferring from a local or international school in the greater Zagreb area. 
Criteria for Admission

Each candidate's application materials are carefully reviewed to assess the applicant's potential for success as a student at AISZ. The following list, while not exhaustive nor in any particular order, describes criteria that are taken into consideration during the admissions process. 

  • School reports, recommendations, and references from previous schools
  • Academic performance
  • Credits eligible for AISZ diploma for Upper School applicants
  • Behavior/discipline records
  • EAL proficiency based upon experience and testing results for students in Grades 6-12 who are not native English speakers
  • Student interview (as requested and required by the admissions committee)
  • Program requirements and AISZ resourcing (e.g. AISZ may not offer some IB courses required by students, notably in languages) 
  • IB/DP only: Students may be required to take a specific Language A course for acceptance (e.g. Chinese A or Croatian A)
  • Learning Support needs to include documentation of all support received at previous schools, IEPs, psychoeducational assessment reports, and any other relevant documentation (not older than 3 years)
Enrolment Requirements

The following enrolment requirements are adhered to:

  • Pre-Kindergarten students must be 3 or 4 years of age by September 1. Priority will be given to students who are 4 years old.
  • Kindergarten students must be 5 years of age by September 1.
  • Grades 1-12 students are placed in a class compatible with their age on evidence of successful completion of the preceding grade or year.
Joining AISZ Mid-Year

Students moving from a school where the academic year ends partway through the AISZ school year will continue in the same grade. For example, if a student has successfully completed the AISZ equivalent of Grade 4 in December at their current school, that student will remain in Grade 4 for the second semester at AISZ (January - June). If a student has successfully completed half of grade 4 by the time they are to begin school at AISZ in August, then they will complete a full year of Grade 4 at AISZ (August - June). Exceptions to this will be made at the school’s discretion only if the school determines that it is demonstrably evident that the student would be better served in a different grade level.

Student Support Services

AISZ strives to service students’ needs to the extent of the resources available. At this time, the school is unable to diagnose students or to provide long term remediation and therapeutic treatment plans. If a child’s needs reach a level beyond our service capabilities, the school may refer and recommend for outside educational evaluations, remediation programmes, consultations and therapeutic services at extra cost to the family or may recommend a different learning program altogether. 

Families are advised that Zagreb offers little opportunity for external educational, psychological, and other assessments to be undertaken in English. As such recommendations for such may involve accessing these services in other countries such as Austria.  We can advise families directly if this is the case. 

Our Admission Policy and Student Support Team does not provide services for students requiring Intensive Support. 

Due to limited resources, we are unable to support students requiring the following levels of intervention:

  • A self-contained intensive learning classroom or life skills program.
  • Special day classes.
  • Severe behavioural support training.
  • Complex and comprehensive curricular modifications or individually designed inclusion opportunities.
  • Adaptive physical education and / or physical therapy and motor support.
