Educational achievement is a very important issue for parents, teachers, and the government. An accurate measurement plays a very important role in evaluating achievement fairly, and, therefore, analysis methods have been developed considerably in recent years. Education based on long-time learning processes forms a fruitful base for item tests,…

Issues regarding confidence and tolerance intervals are discussed within the context of educational measurement. Conceptual distinctions are drawn between these two types of intervals; and examples, under various error and true score models, are used to compare such intervals. It is shown that there tend to be only small differences in tolerance…

Proposes new method for calculating probability that student meets eligibility criteria for special education which avoids the distortion of dichotomous classification, uses multiple sources and measurement error in a meaningful manner, and promotes the accurate use of test data in eligibility decisions.

A 15-MONTH EVALUATION RESEARCH STUDY OF THE 1965 SUMMER HEAD START PROGRAMS WAS CONDUCTED THROUGHOUT THE STATE OF TEXAS. A SCHEMATIC MODEL OF INTERACTING FACTORS OPERATING THROUGH HEAD START PROGRAMS TO PRODUCE AND PREDICT CHANGES IN EDUCATIONAL DEVELOPMENT AND IN OUT-OF-SCHOOL ENVIRONMENT WAS DEVELOPED. THIS MODEL GENERATED THE EMPIRICAL…

A defense of the System of Multicultural Pluralistic Assessment (SOMPA) in response to previous articles in this issue of this journal is presented by the test developer. The defense is detailed and addresses each previous article. (JKS)

This set of policy statements is intended to provide guidance to those who evaluate and select assessments, prepare students for those assessments, administer and score the tests, and interpret and use assessment results to make decisions about students and schools. The focus is on large-scale assessments that have consequences for students 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…

A review of the literature on automated psychological testing shows that most research and development in this area is based on a one-test, one-psychologist model. In this model, the functions of test administration, scoring, and interpretation are thought out in terms of specific tests presented on an individualized basis. However, more complete…

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)

To what degree testing can become adaptive is considered in three ways: from a formal methodological perspective; from a human process, stability, perspective; and from a sub-system or component view within an adaptive instructional system (AIS). With the advent of large computer-based training systems, the opportunity to broadly implement…

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.…
