The performance of adult males on the Minnesota Paper Form Board Test and the O'Rourke Mechanical Aptitude Test

Abstract

The WPA Education Program of Northern California has administered the Minnesota Paper Form Board Test, Series AA, and the O'Rourke Mechanical Aptitude Test, Form C, to 785 men ranging in age from 20 to 65 years, tending to cluster around 39-43, and varying in schooling from none to the equivalent of a Ph.D. degree, clustering around 8-9 years of schooling. The obtained distribution of scores for the O'Rourke test corresponds well with the published norms based on 70,000 cases. The distribution of scores on the Minnesota test does not correspond well with the published norms based on 76 cases, the published norms being higher. A question is raised concerning the adequacy of these latter norms. Percentile norms for the 785 new cases are presented for both tests. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
