The Porteus Maze test (PMT) is a psychological test. It is designed to measure psychological planning capacity and foresight. It is a nonverbal test of intelligence. It was developed by University of Hawaii psychology Professor Stanley Porteus.[1]
The test consists of a set of mazes for the subject to solve. The mazes are of varying complexity. The test runs for 15–60 minutes, allowing the subject to solve as many mazes as possible.[2] The test serves as a supplementary subtest of the Wechsler intelligence scales.[3]
The test is suitable for ages 3 and up. The original version was developed by Porteus when he was head teacher of the Victorian Education Department's first special school in Melbourne, Australia. Porteus developed his idea further when he migrated to Vineland, New Jersey and then Hawaii. The "Vineland Series", is an intermediate form. Additional mazes were provided in the Porteus Maze Extension and the Porteus Maze Supplement.
