In April of 1982, the German Federal Armed Forces initiated the first empirical pilot project in the area of computerized adaptive testing (CAT). The configuration of hardware, psychological section, and physiological section is discussed, as well as two current problems (data transfer from the TEST 2000 microcomputer to a large sized computer for further calibrations and graphic items that are written in Assembler language in connection with a graphic processor). The first phase started with the standard test battery for entrance into the Armed Forces, the Aptitude Classification Battery (EVT). Six timed subtests of the EVT are on the computer in two parallel forms. Results from the data of 208 examinees taking the EVT by paper-and-pencil and then by computer were calculated. The comparison using the t test for dependent samples shows significant mean differences except for Arithmetic. The verbal subtests of paper subtests had higher scores, while the figural subtests using computerized testing had higher scores. Future developments discussed included the following: (1) a hardware change (an integrated testing station); (2) a second empirical phase (addition of adaptive testing with fixed branching strategies); and (3) a third empirical phase (evaluation of variable branching strategies in adaptive testing).
