Average score change: How big is big? This paper discusses school-level changes in average ACT scores and highlights an interactive tool designed to facilitate score change comparisons.

States and districts have expressed interest in administering the ACT® to 10th-grade students. Given that the ACT was designed to be administered in the spring of 11th grade or fall of 12th grade, the appropriateness of this use should be evaluated. As such, the focus of this paper is to summarize empirical evidence evaluating the use of the ACT…

Views on testing--its purpose and uses and how its data are analyzed--are related to one's perspective on test takers. Test takers can be viewed as learners, examinees, or contestants. I briefly discuss the perspective of test takers as learners. I maintain that much of psychometrics views test takers as examinees. I discuss test takers as a…

This study of four national English language arts college readiness standards sets compares content alignment and level of alignment of the standards statements in three comparison sets to a benchmark set, the American Diploma Project (ADP), and analyzes the cognitive complexity of all four sets. Specifically, this report addresses two primary…

This manual contains information about the American College Test (ACT) Plan® program. The principal focus of this manual is to document the Plan program's technical adequacy in light of its intended purposes. This manual supersedes the 2011 edition. The content of this manual responds to requirements of the testing industry as established in the…

The benefits of item response theory (IRT) will only accrue to a testing program to the extent that model assumptions are met. Obtaining accurate item parameter estimates is a critical first step. However, the sample sizes required for stable parameter estimation are often difficult to obtain in practice, particularly for the more complex models.…

A procedure is described for estimating the reliability and conditional standard errors of measurement of scale scores incorporating the discrete transformation of raw scores to scale scores. The method is illustrated using a strong true score model, and practical applications are described. (SLD)

The American College Testing Program (ACT) is field testing a portfolio assessment model. The field test is designed to determine whether it is possible to implement a portfolio assessment model on a national level that will result in scores that are of sufficient reliability and validity that they can be used for decisions at the student level.…

A study was conducted at North Harris County College to determine the extent to which its Developmental Studies Program (DSP) was meeting stated goals and to assess the predictive reliability of the screening tests used to place incoming students in DSP courses. The study involved: (1) an assessment of the need for the DSP program as evidenced by…
