A computerized flexilevel test was implemented and its ability estimates were compared with those of a Bayesian estimation based computerized adaptive test (CAT) as well as with known true ability estimates. Results showed that when the flexilevel test was terminated according to Lord's criterion, its ability estimates were highly and significantly correlated with those of the Bayesian based CAT and with the known true thetas. Matched t-tests between the flexilevel and the Bayesian CAT and with the known true thetas were not significantly different from one another. The primary implication of this study is that it is feasible to implement a computerized adaptive test without having to create a calibrated item pool containing 200 or more items, as is the case with Item Response Theory (IRT) based CAT systems. Neither the software nor the hardware needed for flexilevel CAT methods present the rather serious obstacles that they often do for IRT-based CAT. This fact and the result that flexilevel CAT ability estimates compare favorably with the IRT-based CAT ability estimates indicate that, for the first time, CAT procedures can be made practical and feasible for ordinary classroom testing.
