Diagrammatic Test Characteristics

Learn about the most popular types of diagrammatic reasoning tests currently being used by various companies and organisations today. 

Letter and Number Diagrams

This test type includes a number of diagrams which contain combinations of letters that can be modified by different rules or commands. These commands are represented by numbers. Each number symbolises one rule, and these numbers may appear more than once in a diagram. However, the meanings of the numbers can vary from one diagram to the next. Your task is to follow the paths indicated by the arrows and determine the effect each command has on the letter combinations. Then, apply the commands to the corresponding problem. 


Shape Diagrams

This test type includes a number of diagrams in which shapes can be modified by different operators. A panel illustrates different operators and their effect on different shapes. Your task is to infer the rules dictated by the operators and to apply them to new situations.
