The tests were taken by students from Grade 3 to Grade 10. Below are the average test scores by grade in each of the four test areas:
Reading
Writing - Narrative / Reflective
Writing - Exposition / Argument
Mathematical Literacy
The charts show the average for ISP students compared to the world-wide average scores in the same grade. Because the worldwide average results do vary each year differences of less than 20 are unlikely to be statistically significant.
In the charts through 2023 below we track the average scores for each grade cohort over time. Some grades have a slightly longer 'history' than others because we staggered the introduction of these tests. Also note, due to ISP transient student populations, the number of the same students continuing within a particular grade cohort greatly diminishes over a five year period.
