ISA Testing

What is the ISA?

The International Schools’ Assessment (ISA) is a high-quality assessment used by international schools and schools with an international focus to monitor student performance over time and to confirm that their internal assessments are aligned with international expectations of performance. The ISA is not based on any one curriculum but tests core skills in mathematical literacy, reading, writing and scientific literacy. The ISA test material is as culturally inclusive as possible. The ISA is designed and developed by ACER and the ISA reading, mathematical literacy and scientific literacy assessments are based on the Programme for International Student Assessment (PISA).

We are pleased to announce that ISB students have performed at or above international averages.  The Grade 8, 9 and 10 students performed above PISA averages which are set for 15 year olds (Grade 10 Students). They out-performed the Bremen, Germany and Bayern in all subjects and match and outscored high performing International schools and areas.

Well done ISB students, keep up the good work!
