Choosing a test type and level

Choosing a test type

CAT4 comes in two formats: CAT4 (paper version, UK only) and CAT4 Digital.

Please note that Level Y is available in paper form only, and unavailable outside the UK.

CAT4 Paper

To administer CAT4 using the paper format, you will need the following items for the chosen level:

  • Student booklets: where pupils read the questions.
  • Optical Mark Recognition (OMR) answer sheets: where pupils mark their answers.
  • Scoring service: Group Header Sheet (included in answer sheet packs) for each test group.

Answer sheets and Group Header Sheet are submitted to GL Assessment for the computerised scoring service.

Schools have the option of purchasing our overprinting service, which delivers answer sheets pre-printed with pupils' information, to save time during administration and the scoring process.

Choosing a test level

CAT4 has 10 available levels in the UK and 9 internationally. The levels are aimed at different age groups and the test content of each level is developed in an overlapping format of progression difficulty. 

The target year group and age range covered by the norms for each test level are shown in the tables below.

Please see ‘How do I choose a test level’ in the Teacher Guidance for more information.

Exceptions to recommended year groups

In certain situations, a school may choose to use a lower or higher level of CAT4 than recommended in the table. Some examples are:

  • A school that tests students before they transition to their next school, where the next level up may be more appropriate. 
  • A selective school that tests a year group composed of highly able students, where the next level up may be used. Or a non-selective school in a selective area, where the next level down may be appropriate.

Such cases are the exception rather than the rule. On the rare occasion when individual students fall outside the age range, their scores will be based on the upper or lower end of the age range of the level of CAT4 they have taken. So, a student taking CAT4 Level B who is 11:06 will receive scores based on the upper age limit of 10:11.
