Porteus Maze Test

The Porteus Maze test (PMT) is a psychological test, designed to measure psychological planning capacity and foresight in children, adolescents, and adults. This nonverbal test of intelligence was developed by University of Hawaii psychology Professor Stanley Porteus. Maze test consists of a set of paper forms in which the subject is required to trace a path through a drawn maze of varying complexity with a limit of 15–60 minutes to perform this test. The subject must avoid blind alleys and dead ends; no back-tracking is allowed. A maze procedure is also involved as a supplementary subtest of the Wechsler intelligence scales as it allows for a wide range of application.
