Rasch Consultants

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.

Consultant in Rasch, logistic models and classical models for educational evaluation and biostatistics. I give technical support from the design of a test to item analysis. I produce the family of KALT programs (including item banking, classical item analysis, on-line testing including Rasch model and criterion-referenced test and item analysis) and offer technical support and training (test design, Rasch analysis, item design and analysis). An interesting service that I am offering since 2000 is the "Analysis of quality of a test" according to international standards (among the areas that we evaluate are: validity, objectivity, reliability, logistics and application, fair test practices, research, etc.) , in this case the institution provides information and evidences of a set of elements of the test and we provide a technical report indicating the areas that are correct and the areas needing an improvement according to the standards. I can offer my services in English, Spanish and French.
