The British International School of Zagreb offers a standardised programme aligned with the UK National Curriculum. The programme is taught in English, with foreign languages provided as supplementary electives. Admission is open to any student who meets the expected requirements. The admission procedure begins with families contacting the school by phone or email to arrange an interview and a tour with the Director/Principal and/or the School Coordinator. The initial visit allows students and parents to ask questions, meet teachers, and gain a clear understanding of how the school operates. A second follow‑up interview is arranged, and the school requires copies of the last two school reports along with completed application forms to be returned; these documents are reviewed by the Principal and school leadership and parents are informed as soon as possible. Prospective students are assessed before an offer is made. Primary School assessments are conducted by the Primary School Coordinator and involve standardised testing in Literacy and Numeracy; Secondary School assessments include subject‑specific assessments and a Skype interview if the student is abroad. Assessments for Secondary School students are conducted by the relevant subject teachers and the coordinator, and the school may identify the need for private English tuition, which is charged in addition. The school offers a one‑off open day for prospective students to spend a day in class to observe how lessons operate. If a student is deemed eligible for admission, parents receive an acceptance form/contract in three copies to be signed, and they must pay a non‑ refundable Admission Fee before the child's name is placed on the class list. The Principal may refuse admission if the student would not gain educational advantage from BISZ programmes, if the student has a low academic or disciplinary record deemed unsuitable for the BISZ community, or if the school cannot meet the student's special educational requirements. Enrolment is organised so that Grades 1–13 are placed in a class appropriate for their age based on successful completion of the preceding year, and students moving from Southern Hemisphere schools continue in the same grade (e.g., finishing Grade 6 in Australia in December would complete the school year in Grade 6 at BISZ from January to June). The following documents are required: 1. Application forms, 2) School records for the previous two years, 3) Confidential school recommendations, 4) Official English translations of school records, 5) Proof of payment of the admission fee, 6) Copy of the passport photo page, 7) Copy of the birth certificate, 8) Enrolment Contract, 9) Copy of the child's relevant medical information or vaccination records, 10) For Kindergarten and Year 1, the pediatrician's certificate stating that the child is ready for school.
