This manual contains technical information about the ACT® college readiness assessment. The principal purpose of this manual is to document the technical characteristics of the ACT in light of its intended purposes. ACT regularly conducts research as part of the ongoing formative evaluation of its programs. The research is intended to ensure that…

This manual was written to provide technical information regarding the General Educational Development (GED®) test as evidence that the GED® test is technically sound. Throughout this manual, documentation is provided regarding the development of the GED® test and data collection activities, as well as evidence of reliability and validity. This…

Equating is an essential tool in educational assessment due the critical role it plays in several key areas: establishing validity across forms and years; fairness; test security; and, increasingly, continuity in programs that release items or require ongoing development. Although the practice of equating is rooted in long standing practices that…

This handbook outlines procedures for sharing student data between schools and the Ministry of Education, and answers questions pertaining to provincial examinations. It supports the work of both educators and the Ministry, which works with schools to produce transcripts and administer provincial exams. The following are appended: (1) Forms; and…

The purposes of this paper are five-fold to discuss: (1) when item response theory (IRT) equating methods should provide better results than traditional methods; (2) which IRT model, the three-parameter logistic or the one-parameter logistic (Rasch), is the most reasonable to use; (3) what unique contributions IRT methods can offer the equating…

Based on the experiences of four equating studies conducted by the Austin (Texas) Independent School District, a practical "cookbook" approach to test equating is presented. Three types of equating procedures are discussed: choosing a cutoff score on a new instrument, predicting Y from X, and symmetric equating of X and Y. (BW)

This chapter helps the general reader to understand the test equating issues associated with test disclosure. It also helps the testing practitioner to recognize situations in which equating is necessary, and to understand how to accomplish various kinds of equating. (Author/BW)

The central idea in building and maintaining an item bank is to calibrate all the items onto a "common variable." The arithmetic involved in the calibration process is presented. It is recommended that an analysis of fit be done in every application to verify that the estimates of item difficulties are in fact sample-free. These…

In Rasch terminology, two or more tests are linked when they are joined into a pool related to a single scale. When the same item calibrates at a low level on one test and a high level on a second test, it indicates that the item is low on the first test because the other items on that test are higher, and is high on the second test because the…

Criticisms of norm referenced standardized tests are contrasted with the assumption and claims of proponents of Rasch model testing and item banking. The Rasch test theory model is based on the assumption of equal interval curriculum referenced scales for both students' abilities and test item difficulties. The Portland school district has…

A minimum standards amendment to the New Jersey Public School Act of 1975 requires the testing of public school students to determine proficiency in the minimum basic skills of reading and mathematics, under the auspices of the New Jersey State Department of Education's Educational Assessment Program. To meet the mandates of this amendment, the…

The Basic Occupational Literacy Test (BOLT) measures basic skills of educationally disadvantaged adults in four content areas: reading comprehension, reading vocabulary, arithmetic computation, and arithmetic reasoning. Alternate forms of each subtest are available at each of three or four levels of difficulty. The Wide Range Scale is used to…

Out of level testing is defined and reasons for administering out of level tests, especially in compensatory education programs are explained: (1) to achieve optimum test reliability; (2) to test student achievement--provided out of level test scores are interpreted in terms of the appropriate in-level population; (3) to avoid carelessness and…

The Basic Occupational Literacy Test (BOLT) was developed as an achievement test of basic skills in reading and arithmetic, for educationally disadvantaged adults. The objective was to develop a test appropriate for this population with regard to content, format, instructions, timing, norms, and difficulty level. A major issue, the use of grade…

This manual contains preliminary information, largely of a technical nature, about the enhanced American College Testing (ACT) Program introduced in October 1989. It focuses primarily on the tests of educational development, the component of the program that has been substantially revised. Although one-third of the ACT Interest Inventory Items has…
