Teaching and Learning at TBS (Secondary and IB)

Using data to support student assessments: Each week we will be sharing information with you that relates to teaching and learning here at TBS.

secondary students

One of the key aspects of effective teaching is really knowing the students you are teaching. Although you will frequently hear us say that we make judgements using a range of evidence, one of the key sources of evidence that we use are baseline test scores. We use a product called CAT4 from GL Assessment that I would like to further explain:

What is CAT4?

The Cognitive Abilities Test (CAT4) is a diagnostic assessment designed to help schools and teachers in understanding each student’s academic potential.

Why do we use CAT4?

The tests assess how students think in areas that are known to make a difference to learning. Many tests focus on a child’s attainment in core subjects, but CAT4 is designed to give a much broader, more rounded view of each child, their potential and how they learn.

What does CAT4 test?

Tasks involve thinking about shapes and patterns (Non-Verbal Reasoning), words (Verbal Reasoning), numbers (Quantitative Reasoning) and some questions are answered by mentally generating and transforming visual images (Spatial Ability).

How do we use them?

Here at TBS Warsaw, CAT4 tests allow us to gain an understanding of what a child is capable of rather than judging them by their understanding of knowledge in particular subjects. Tests are age dependent, and all students take CAT4 tests in Year 7, 10 and 12, or at the time of joining if this is during a school year.

Finally, please remember that CAT4 scores are just one piece of the jigsaw that we use to build a picture of your child’s academic potential. The test scores do not define your child, but instead help us to ensure that we are providing the best level of challenge and support for your son or daughter.
