St. John’s recently compared the ISA scores of 30 St. John’s students who progressed through the school from grade 5 to grade 8. We took their grade 5 International Schools Assessment (ISA) scores in the four categories: Reading, Writing A (Narrative) and B (Exposition/Argument) and Math. A student’s score in the ISA tests will normally increase from 5th to 8th grade. The increase for the average student taking these tests worldwide was calculated and provided a benchmark against which this group of students could be compared.
What we found is that the group of St. John’s students exceeded the predicted score in each of the four categories. In Reading, the students managed to beat the predicted score by 4.3%. In Writing A, they exceeded the expected score by 7.6%, while Reading B scores were a stunning 26.7% higher than could have been expected. In Math, the score obtained by the 30 students who have been at St. John’s from at least grade 5, was 11.4% higher than predicted.
Knowing that 17 of the 30 students are non-native English speakers makes this achievement all the more remarkable.
The International Schools’ Assessment (ISA) is designed especially for students in international schools in Grades 3 to 10. It is based on the internationally endorsed reading, mathematical literacy and scientific literacy frameworks of the Organization for Economic Cooperation and Development’s (OECD) Program for International Student Assessment (PISA). The ISA measures: reading, mathematical literacy, writing, and scientific literacy. Over 31 000 students from 122 schools participated in ISA October 2012.
