The multilevel characteristics of test item data are considered as a method for examining the characteristics of standardized norm-referenced tests. A theoretical rationale for examining multilevel characteristics is presented. It can be used as an aid to understand why program and instructional effects on measures constructed from…

Computer generated data are used to show that Slinde and Linn's criticism of the usefulness of the Rasch model for equating (EJ 189 585) may have been the result of an artifact produced by the manner in which the samples were chosen in their study. (CTM)

Ten studies investigating the relationship between instructional time and achievement on elementary school reading and mathematics tests were reviewed. The studies involved general classroom research, instructional time research, and attention research. The review indicated that the relationship between academic achievement and instructional time…

This paper analyzes Jencks et al's (1983) and Hauser et al's (1983) reports of their research on the Wisconsin status attainment model. For example, the meaning and interpretation of "unmeasured" family background are discussed and the charge that the status attainment model ignores social structure is examined. (Author/IS)

The Elementary and Secondary Education Act Title I Evaluation and Reporting System is a method for giving a federally funded project in reading or math an overall score on its cognitive effectiveness.

Data from Project Talent are utilized to assess the representativeness of the samples used in the Wisconsin and the Exploration in Equality of Opportunity (EEO) surveys. Adequacy of the measures of academic aptitude and aspiration used in the surveys are examined, and problems with the Wisconsin model are briefly discussed. (RM)

An analysis of the Wisconsin model of achievement asks how powerful this model is in accounting for social influences, aspirations, and attainment when measurement error is taken into account.
