Value-Added Service for IGCSE

Value-Added Service for IGCSE

The GL Education Value-Added Service provides a quantifiable measure of the impact your school’s teaching has had on its students. The service provides evidence that gives a richer understanding of a school’s performance considering the starting point of each student using CAT4 as the baseline measure.

What CAT4 data do I need?

To get value-added scores you will need to have tested the students with CAT4 in one of the years before they sat their exams as set out in this table:
