CEM Primary Assessments

As your pupil progresses from early years into primary school, our adaptive baseline assessments work to continue that strong foundation and unlock potential for primary school children aged 5-11. We have two baseline assessments that work towards this goal: BASE (for 4-5-year-olds) and Cambridge Primary Insight (for 5-11-year-olds).

Read on to find out which assessment is right for your pupil, and how you can map their learning journey throughout school.

Primary school children working


discover what children know and can do from the start

Support early learning and development.

A fun, interactive assessment, BASE is a tool that takes just 20 minutes and feels more like a game than a test. Demonstrate progress across their first year in school and gain empowering insight that will help you tailor teaching plans to best support your students.

For teachers in international schools, BASE complements the Cambridge Primary programme, and works seamlessly with the subject knowledge assessments to help generate a larger picture of your pupils’ learning pace and stage.

What is BASE?

BASE is, in short, a ‘baseline assessment’. BASE gives you a clearer picture of every child in your class through a fun, story-based assessment so you can help them flourish and grow. BASE can be used at the start of the year, as a fun first assessment that allows you to spot potential issues early, and then again at the end of the year to celebrate their progression.

The BASE focus areas:

The first year in school is critical in a child’s learning journey. Based on over 30 years of research, BASE focuses on the following so you can identify those vital opportunities for support:

  • Literacy
  • Numeracy
  • Communication
  • Language
  • Personal, social and emotional development
