Of interest in this study was the use of item response
models for obtaining accurate examinee domain
score estimates and for increasing the probabilities
with which examinees are assigned correctly
to mastery states with criterion-referenced test
scores. Specifically, the purpose of this investigation
was to compare the one-, two-, and three-parameter
logistic test models for estimating domain scores
and making mastery/nonmastery decisions. Computer
simulation methods were used to recover a set
of true domain scores with each of the logistic test
models under a variety of testing conditions. Also,
the percent of times the use of each model led to
decisions which were consistent with decisions made
with the true domain scores was studied. The one-parameter
and three-parameter model resulted in
highly comparable results for middle and high ability
examinees, while for low ability examinees, the
more general model always performed somewhat better.
