Secondary Baseline Assessments

Our secondary baseline assessments are there so you can discover and progress your students’ potential as they start and progress through secondary school.

Spanning from ages 11 to 16, our MidYIS and Yellis assessments are designed to help predict up to GCSE and IGCSE. They test a range of sections including vocabulary, maths, and non-verbal skills, with an average duration of 50 minutes for both tests.
