What if my child does not speak English yet?

To ensure all students can benefit from the curriculum, the school provides an English Language Acquisition (ELA) programme for learners whose first language is not English. Older students from grade 9 and above will need to demonstrate they have sufficient English to be able to access the curriculum. This means your child(ren) may be asked to take a language assessment as part of the enrolment process.. Please also look at our language acquisition page.

What support does ISU offer?

To proactively address the academic, behavioural and social-emotional needs of the students, our school provides additional support. For more information, please view the inclusion page.

Does the school provide childcare?

The school offers places to children who have had their 4th birthday. We do work closely with Kind & Co Ludens , a separate organisation that offers childcare to children under 4. Kind & Co Ludens also offers after school care (in Dutch: BSO) in our school building. For information & registration please view our After School Activities & Care page.

Where do our school families live?

Please view the ISU Fact Sheet for some more information on student numbers and nationalities, staff nationalities and where our school families live. We will update this information twice every academic year, in the autumn and spring.

Is there a school bus?
No, there is no school bus, but public transport in the city of Utrecht and surrounding areas is well organised.
