The primary focus of Measurement Research Associates, Inc. is to provide personalized
examination development, analysis and reporting services. Services include the following.
Traditional statistical analyses are performed for written multiple choice examinations. Criterion
referenced standard setting methods (e.g., bookmark) can be explained and implemented.
Latent trait analysis,
using the Rasch model, offers additional information about the performance of written multiple
choice examinations. Using the Rasch model, examination equating ensures
that the same
standard is used across examination administrations. Multi-facet Rasch analysis has been used
successfully for oral, practical, case and other examinations that requir
e the intervention of a rater.
The impact of all facets of the examination are accounted for, including
rater severity, item or
case difficulty, and skill difficulty. The reliability of the examinati on is enhanced, because the
error of measurement is decreased. Thus, multi-facet examinations can be
shown to be reliable, as
well as, valid. Computerized adaptive testing is a method of using the
power of the computer to
construct individualized tests for each candidate, thus decreasing the error of measurement more
quickly, so that tests can be shorter without sacrificing precision or confidence in the pass/fail
decisions. Test security is potentially improved by using adaptive testing.
