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.

ACT reporting categories and ACT Readiness Ranges are new features added to the ACT score reports starting in fall 2016. For each reporting category, the number correct score, the maximum points possible, the percent correct, and the ACT Readiness Range, along with an indicator of whether the reporting category score falls within the Readiness…

Over the past decade, there has been greater recognition by educators, employers, and policymakers of the importance of behavioral skills and navigation factors (e.g., dependability, cooperation, interests, and goals) for education and career success. A growing body of research shows that these factors contribute to diverse positive outcomes in…

Composite scores are often formed from test scores on educational achievement test batteries to provide a single index of achievement over two or more content areas or two or more item types on that test. Composite scores are subject to measurement error, and as with scores on individual tests, the amount of error variability typically depends on…

Data from 181 college students were used to assess whether math reasoning item response times in computerized testing can provide valid and reliable measures of a speed dimension. The alternate forms reliability of the speed dimension was .85. A two-dimensional structural equation model suggests that the speed dimension is related to the accuracy…

If numerical reasoning items are administered under time limits, will two dimensions be required to account for the responses, a numerical ability dimension and a speed dimension? A total of 182 college students answered 74 numerical reasoning items. Every item was taken with and without time limits by half the students. Three psychometric models…

Because it is often impractical or impossible to obtain school transcripts or records on subjects, many researchers rely on college students to accurately self-report their academic record as part of their data collection procedures. The purpose of this study is to investigate the validity and reliability of student self-reported academic…

This study tests a process model of learning in which trainer and trainee traits are simultaneously considered as endogenous variables of learning outcomes. The article builds on a social view of training and similarity-attraction paradigms. In this context, the authors hypothesize that trainer-trainee similarity in personality (agreeableness)…

We examine the history of VMI's use of the Major Field Test as an assessment tool for its Department of Economics and Business. Further, we chronicle how the information gathered from a decade and a half of use has shaped the curriculum, faculty composition and policies within the Department. There is evidence that the policies surrounding how and…

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.…

The stability of selected indices for detecting differential item performance (item bias), from one randomly equivalent sample to another, is addressed. Some recent research has criticized these indices as too unreliable for utility in measuring bias in achievement test items. Using data from a national testing of the ACT Assessment, however, this…

The High School Course/Grade Information Section (CGIS) of the American College Testing (ACT) Assessment registration folder collects detailed information about the courses students have taken or plan to take in high school, and the grades they have earned in courses they have completed. In this study, data provided by students on the CGIS were…

This paper examines the accuracy of student-reported demographic characteristics, activities, and accomplishments provided through the American College Testing (ACT) Assessment Program. The accuracy of five background characteristics, nine extracurricular activities, and 15 special accomplishments reported by students completing the ACT Assessment…

Prepared by the Research and Development Division of the American College Testing (ACT) Program, this handbook contains information pertaining to the ACT Career Planning Program, a guidance program for students considering and entering post-high school career education programs. The primary instrument of the Career Planning Program is a Career…

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)
