Over the past thirty years, obtaining diagnostic information from examinees' item responses has become an increasingly important feature of educational and psychological testing. The objective can be achieved by sequentially selecting multidimensional items to fit the class of latent traits being assessed, and therefore Multidimensional…

Computer simulation was used to assess the effects of item parameter estimation errors on different item selection strategies used in adaptive and conventional testing. To determine whether these effects reduced the advantages of certain optimal item selection strategies, simulations were repeated in the presence and absence of item parameter…

A functional design model for a computerized adaptive testing (CAT) system was developed and presented through a series of hierarchy plus input-process-output (HIPO) diagrams. System functions were translated into system structure: specifically, into 34 software components. Implementation of the design in a physical system was addressed through…

The relationship between selected subtests from the Armed Services Vocational Aptitude Battery (ASVAB) and corresponding subtests administered as computerized adaptive tests (CAT) was investigated using a sample of Marine recruits. Results showed that the CAT subtest scores correlated as well with initial ASVAB scores as did ASVAB retest scores,…

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…

A mail survey about the use of instruments in 9 assessment areas was answered by 389 school psychologists. Comparison with a similar survey 10 years earlier suggests no decline in assessment overall, although emphasis is switching away from intelligence testing, toward achievement testing, behavior rating, and adaptive measurements.
