Academic Performance

At ISB, education is designed around the understanding that no two students are the same. Our flexible, inquiry-based curriculum is built to support personalised learning pathways that reflect each student’s individual needs, interests, and strengths. Rather than focusing solely on exam performance, ISB emphasises the development of critical thinking, creativity, global citizenship, and future-focused skills that are essential for success in an unpredictable world.

ISB’s academic performance on external assessments, outlined below, demonstrates that our personalised approach delivers outstanding results compared to traditional educational models.

How does ISB compare to other ‘selective’ schools?

Each year, families ask us to compare our results to selective schools around the world. These two data points that help families assess how well our students perform against peers in other schools.

MEASURES OF ACADEMIC PROGRESS (MAP)

MAP gives us a breakdown of our students' performance levels (Low, Low Average, Average, High Average and High). Students performing at the High Average and High levels are above the 60th percentile, meaning that they performed better than 60% of the norm-group students who took the test.

Map Growth Testing

Map Growth Testing

At ISB, we check student progress via a standardised assessment (MAP).

As part of MAP data analysis, our teaching teams cross-reference a student’s growth rate with their achievement within the subjects reported below. If a student has a high rate of growth, they are experiencing the appropriate challenge within the classroom to continue along their pathway.

For those students who are not experiencing a typical rate of growth, we use other measures such as the NNAT3 and classroom performance to investigate further. Our faculty and staff not only ensure that students are demonstrating competency in basic subject areas, but are also key in facilitating student growth and challenge through their ISB experience. We also use other tests for a variety of purposes.
