International Schools' Assessment 2018

The results are back from our February 2018 participation in the International Schools’ Assessment (ISA). In the February 2018 exams, 221 international schools and over 42,700 students from grades 3 to 10 participated in ISA.

The ISA is a critical international benchmarking measure for international schools, testing mathematical literacy, reading comprehension, and narrative and argumentative writing of students around the world.

Not only do the tests enable schools to assess their overall progress as an institution, but they also help identify strengths and weaknesses according to year group, class, subject and student. This valuable feedback helps guide us to make decisions that will best support our students here at SIS Zürich-Wollishofen.

Based on thorough analysis of this year’s results, we are satisfied with our students’ progress. Individual ISA results have been given to the children after having a short chat with the classroom teacher.
