This article provides information and advice about when and how frequently to administer ACER General Ability Tests (AGAT) to your students.
When to assess
Generally, AGAT is administered to students once per year. The AGAT scale enables teachers to monitor and compare students’ general ability measures over time. For the purpose of monitoring student progress, a gap of 9 to 12 months between AGAT testing sessions is recommended. Learning progress may not be reflected in a student’s AGAT scale scores over a shorter period of time. Longitudinal growth should be measured over a minimum of two years of schooling, or three separate testing sessions, in most contexts. This will help account for possible scale score variation, for example where external factors may affect a student’s performance on a particular testing occasion.
