The methodology to perform benefit-cost studies exists, but there is much ambiguity concerning the implications of such studies as a result of using faulty methodology. For example, control groups are a necessity, as are adequate sampling procedures and adjustment for non-response bias and self-selection bias, and all studies do not employ this…

The measurement information generated by CRT's is designed for use in instructional management systems where classifications of pupils for treatment are to be decided on the basis of minimal data consistent with predetermined limits for the errors of misclassification. The measures obtained are content specific estimates of proficiency useful for…
