The present report describes an exploratory investigation into this problem in the Air Force situation. It represents the first in a series of studies concerned with the utility of certain apparatus and printed manipulative tests as possible additions to the printed Airman Classification Battery. In the present instance, three schools in the Aircraft Maintenance area were selected for study These were the Engine Mechanic (R-4360), Hydraulic Mechanic and Aircraft Electrician (General) courses, all at Chanute Air Force Base. A battery of 16 experimental tests (yielding 25 scores) was administered to students entering these courses Included among these tests were certain printed psychomotor tests designed as possible substitutes for certain of the apparatus tests Validation of all of these tests was achieved against various school criteria.
