Assessments to empower schools

What started off as a personal small-scale research project in 1982 has developed into a whole series of assessments for schools across the world. We help you to uncover students' baseline abilities, understand their capabilities and unlock their full potential. CEM assessments are used by education professionals in 109 countries, and over 481,000 students will be taking a CEM assessment this academic year.

What does InCAS assess?

Students are assessed in these six key developmental areas which research shows are linked to later academic outcomes:

  • Reading
    word recognition, decoding, and comprehension
  • Spelling
  • Mathematics
    includes counting, arithmetic, fractions, patterns, algebra, measures, shape and space, and data handling
  • Mental Arithmetic
    addition, subtraction, multiplication, and division
  • Developed Ability
    picture vocabulary and non-verbal reasoning
  • Attitudes
    students' attitudes to reading, maths, and school

"We use InCAS [now evolved into Cambridge Primary Insight] data to inform planning, set aspirational targets and give parents a picture of how their children are performing amongst a large, diverse cohort, rather than just amongst a class or year group."

Kirsten O' Connor, Head of Primary, The British School in Tokyo
