The International Schools’ Assessment

Each year in October or February, students from different countries participate in the International Schools’ Assessment (ISA), a program developed by the Australian Council for Educational Research (ACER) and designed specifically for international schools. This year 400 schools and 90,000 students participated in ISA Assessment.

The ISA assesses students in the four learning areas of Mathematical Literacy, Scientific Literacy (Only for Junior High School), Reading and Writing, using tests designed for Grades 3, 4, 5, 6, 7, 8, 9, or 10. 

Participating schools receive a comprehensive set of data, which includes the performance of each student and class, aggregated whole school data, and valuable comparisons to Like Schools, Regional Schools, and All Schools.

  • ‘Like School’ groups were developed to allow a more refined comparison to the performance of students in other similar schools, and are based on the proportion of students from English-speaking and non-English-speaking backgrounds. Each school is assigned to one of four groups. 

  • The comparison to ‘Regional Schools’ is a comparison to all other schools in your region who are participating in the ISA. The regional groups are Africa, the Americas, Asia-Pacific, Europe, and the Middle-East.

  •  The ‘All Schools’ comparison is to the aggregated results for all students from all schools in the ISA Reference Norm. Further details on these comparisons and the Reference Norm can be found in the ISA Guide to Reports.  

Abroad International School – Osaka’ s ISA 2023 Report 

We were glad to see that the overall success of our school was above the average when compared to ‘Like Schools’, ‘Regional Schools’, and ‘All Schools’. Seeing some of our students getting the highest scores among ‘All Schools’ made us exceptionally happy. One of the third-grade students in Reading, one fourth-grade student in Mathematical Literacy, one fifth-grade student in Reflective writing, another fifth-grade student in Argument Writing, and one grade 8 students in Mathematical Literacy were top of all participants around the world.
