A computerized adaptive test version of the ASVAB subtests was developed on item pools of approximately 200 items each. The items were pretested using applicants from military entrance processing stations across the US, resulting in a total calibration sample size of approximately 60,000 for the computerized adaptive tests. Three of the 12 models provided reasonable summaries of the data. One model with a multiplicative structure (M. W. Browne; see record 1984-24964-001) performed quite well. This model provides an estimate of the disattenuated method correlation between conventional testing and adaptive testing. In the present data, this correlation was estimated to be 0.97 and 0.98 in the 2 halves of the data. Results support computerized adaptive tests as replacements for conventional tests.
