Non-verbal reasoning is an adaptive subtest involving matrix puzzles that can be solved by a careful application of logical reasoning, using both visual and verbal strategies. Students are shown a 3 × 3 matrix with the bottom right hand square empty. Students choose which of six squares at the bottom of the screen completes the pattern. The student starts by attempting some ‘probe’ items to determine the level at which they should start the subtest. Their progress through the subtest depends on their performance and the subtest is discontinued when the student fails a certain number of items within a level.
