Spatial reasoning tests are widely used during selection processes which require the ability to use practical and visual skills. This type of reasoning test is quite new to the 11+ and it is now tested in GL Assessment tests. It is a skill that is the basis of success in STEM (Science, Technology. Engineering and Maths) subjects and competence is said to be mostly inherited, however, tests have proven that children can improve their skills quite dramatically with targeted practice. Children with an aptitude for maths and science tend to have an aptitude for spatial reasoning questions and most children will have come across some question types in the UK CATS tests.
