Summary A group of 240 mechanical engineers in a large manufacturing plant were examined with a battery of general mental ability and engineering aptitude tests. Percentile norms are presented. Comparisons of relative proficiency were made with test norms for the general population. It was found that mechanical engineers were clearly superior on all tests. Insofar as comparisons could be made between different normative groups, no greater superiority was found on tests which are usually regarded as indicative of engineering aptitude, such as Mechanical Comprehension and Space Relations, than on tests of general intelligence. The engineers also did as well on verbal as on non‐verbal tests. Mechanical Comprehension was much easier for them than Space Relations.
