Through a synthesis of test publisher norms and national longitudinal datasets, this study provides new national norms of academic growth in K-12 reading and math that can be used to reinterpret conventional effect sizes in time units. We propose d' a time-indexed effect size metric to estimate how long it would take for an "untreated"…

While major test publishers randomly select school districts for their national norming studies, a survey of "accepting" and "declining" districts supports the hypothesis that self-selection bias results in overrepresentation of districts which already use a specific publisher's tests or instructional materials.

Analysis of the available data suggests that New York's elementary and secondary schools, taken as a whole, compiled a good record of achievement during the 1982-83 school year. Three kinds of test data were analyzed. One was the result of a study which involved the collection of scores on three commercially available standardized tests: the…

A sizable representative subsample of the standardization group for the Metropolitan Achievement Tests participated in both the Fall and Spring standardization programs. Fall and Spring test records were matched for all such pupils and Fall-Spring "growth expectancies" were derived. Additionally, the sample was split into three subgroups…

Seven criteria for selecting and describing the standardization sample of the Metropolitan Achievement Test (MAT), 1978 edition are discussed. Four major variables were used to describe the sample: socioeconomic status; school district enrollment; public vs. nonpublic; and geographic region. Both forms and all grade levels of the Survey Battery…

This user's manual contains the major products of the data collection of the Anchor Test Study, a 34 volume report equating scores of eight widely used reading tests for grades 4, 5, and 6 in reading comprehension, vocabulary, and total reading. This manual provides: (1) equivalency tables which allow transformation of raw scores on one reading…

The Follow Through experience is beginning to provide compelling evidence bearing upon important policy issues in compensatory education. This evidence, coming as it does from a naturalistic quasi-experiment, cannot draw its plausibility from the conventional statistical inference appropriate to probabilistically-constructed true experiments. The…

Evaluation objectives were to assess the quality of the Bethel Alaska Regional Library/Media Center as an exemplary operation (the Center was established by the Bureau of Indian Affairs' Bethel Agency in 1971 to serve federally operated schools in Southwest Alaska) and to measure the impact of the Center's services on its Eskimo elementary student…
