After you have completed the medical screening, you will sit for a computer-based Manpower APtitude Assessment System (MAPAS) test. MAPAS consists of a series of tests (e.g. psychomotor skills, mental-spatial ability, etc.) to assess the mental abilities of NSFs. The test scores are used to place servicemen in vocations/appointments where their abilities can be best used. The entire test is about 2½ hours.
