A common interpretation of achievement test results is that they provide measures of achievement that are much like other measures we commonly use for height, weight, or the cost of goods. In a limited sense, such interpretations are correct, but some nuances of these interpretations have important implications for the use of achievement test…

When using IRT models in Educational Achievement Testing, the model is as a rule too simple to catch all the relevant dimensions in the test. It is argued that a simple model may nevertheless be useful but that it can be complemented with additional analyses. Such an analysis, called profile analysis, is proposed and applied to the reading data of…

Changes to state tests impact the ability of State Education Agencies (SEAs) to monitor change in performance over time. The purpose of this study was to evaluate the Standardized Performance Growth Index (PGIz), a proposed statistical model for measuring change in student and school performance, across transitions in tests. The PGIz is a…

The concept of dynamic vertical scaling (DVS) from longitudinal point of view has been proposed as comparing to traditional vertical scaling or static vertical scaling (SVS) from cross-sectional perspective. The effects of differences between DVS and SVS on large-scale student achievements have been investigated. The potential application of DVS…

A structure for describing different approaches to testing is generated by identifying five dimensions along which tests differ: test uses, item generation, item revision, assessment of precision, and validation. These dimensions are used to profile tests of reading comprehension. Only norm-referenced achievement tests had an inference system…

The impact of achievement testing on a Spring-Spring vs. a Fall-Spring basis in evaluation of compensatory education programs is examined. The effects of the summer vacation period and crossing test levels were examined. Significant decreases in achievement test scores were found, at all grade levels, between Spring and Fall test administrations.…

The validity of the Comprehensive Tests of Basic Skills (CTBS) and problems associated with inappropriate norms were investigated in eleven senior high schools in Phoenix, Arizona. CTBS validity was assessed in three ways: (1) correlation between test scores and number of courses taken in that subject; (2) correlation between CTBS scores and…

Twelve common errors which can invalidate an otherwise sound evaluation are identified, and ways to avoid them are presented. The hazards are: (1) grade-equivalent scores; (2) inappropriate statistical adjustments with nonequivalent control groups; (3) administering norm-referenced tests at inappropriate times of the school year; (4) inappropriate…

The Dallas (Texas) Independent School District has developed an assessment system that is fully integrated into its learning system, which also includes planning, instruction, and accountability. This paper describes the learning system in Dallas in terms of a four-part model: planning, instruction, assessment, and accountability. Following this,…

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)

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. Revised estimates show support for the Wisconsin model. A revised model is even more powerful for explaining educational and occupational achievement.…
