Compared the level of confidence in pass/fail decisions obtained with computer adaptive tests (CADTs) and pencil-and-paper tests (PPTs). 600 medical technology students took a variable-length CADT and 2 fixed-length PPTs. The CADT was stopped when the examinee ability estimate was either 1.3 times the standard error of measurement above or below the pass/fail point or when a maximum test length was reached. Results show that greater confidence in the accuracy of the pass/fail decisions was obtained for more examinees when the CADT implemented a 90% confidence stopping rule than with PPTs of comparable test length.
