The Porteus Maze Test is a non-verbal test of performance intelligence or non verbal iq. It is a graded set of forms on which the subject of the test traces from a starting point to an exit; the subject must avoid blind alleys along the way.
The mazes vary in complexity. They range in from a simple diamond shape for the average 3-year-old to traverse to intricate labyrinths for adults. There are three sets of mazes: the original (the Vineland series) the Extension and the Supplement.
The administration of the Porteus Maze Test is interpreted from the instructions included in the testing package. The scoring instructions are also included in book that comes with the Porteus Maze Test. The scoring results in a Qualitative or Q score and a Test Age. Many early studies of correlations with other iq tests ranged widely from moderate to high coefficients. Because the Porteus Maze Test is a nonverbal performance test (non verbal IQ Test), one does not expect a high correlation with purely verbal tests, (or verbal iq tests) but the correlation should be at least moderately positive. Researchers note that a correlation coefficient of .50 is representative of studies with other IQ tests. Therefore, correlations with intelligence tests involving spatial abilities, such as the Kohs Blocks and Knox Cubes, are particularly high.
