At ISA, enrollment changes regularly. Occasionally there is a waiting list for specific grades. Priority is given to ISA siblings, international students and then by the application receipt date.

ISA is accredited by the New England Association of Schools and Colleges (NEASC), by the Council of International Schools (CIS) and by the International Baccalaureate.

We offer an extensive extra-curricular programme that includes creative arts, athletics, student government, Model United Nations, grade level challenge trips, music, yearbook, publication, choir, language clubs, chess club, International Awards for Young People and theatre productions.

In addition to athletic extra-curricular activities that are available to students of all ages, ISA offers a full range of competitive sporting activities for students grade 5 and higher. Team sports include basketball, rugby, soccer, swimming, tennis, track and field, softball and volleyball.

ISA follows the appropriate Dutch National Swimming Diploma Programme that focuses on water safety. Children Kindergarten through grade 3 participate in a swimming lesson once a week to train for the A, B and C diplomas. All students in these grade levels are expected to attend swimming lessons.

English is the language of instruction at ISA, and we offer considerable assistance for students who do not speak English or are learning to speak English as an additional language. Students who require this language learning support in Upper School take English as an Additional Language (EAL) classes, taught by specialists and simultaneously follow grade-level appropriate Adapted English classes. In the Lower School an EAL support teacher is assigned to each grade level (grade 1-5) who delivers a combination of withdrawal classes and in-class support in the homeroom class. Pre-kindergarten and Kindergarten students receive EAL support as an alternative to Dutch classes if they need it. The EAL specialists also work closely with teachers in other disciplines to make sure these students have the necessary accommodations and support to ensure their learning in all subject areas. For students entering grade 10 or higher, we require an intermediate or higher level of English proficiency.

We offer an extensive choice of language instruction, which includes Dutch, French,  German,  Japanese, and Mandarin. For students in grades 6 through 10, we offer mother tongue classes in Dutch, French, Japanese and Spanish in addition to English. Mother tongue classes in Dutch, French and Japanese are offered in grades 11 and 12 in addition to English. In the Lower School Dutch is introduced to Pre-Kindergarten and Kindergarten students who are not in the EAL programme. All students in grades 1 -5 study Dutch; EAL beginners study Dutch Culture in English for their first year. After the first year at ISA students in grades 2-5 can opt to study French as an alternative to Dutch. Additional mother tongue language classes are offered on an extra-curricular, private tuition basis.

Admission can be offered to children with mild educational or physical difficulties according to the limited facilities and personnel available. The school’s Student Study Teams, composed of the Lower and Upper School Heads, Student Support Coordinator, Guidance Counselor, Counselor, Learning Support teachers and School Nurse meet regularly to discuss referrals and support strategies for students with special needs.
