Recent developments of person-fit analysis in computerized adaptive testing (CAT) are discussed. Methods from statistical process control are presented that have been proposed to classify an item score pattern as fitting or misfitting the underlying item response theory (IRT) model in a CAT. Most person-fit research in CAT is restricted to…

Computerized adaptive tests (CATs) pose major obstacles to the traditional assessment of differential item functioning (DIF). This paper proposes a modification of the SIBTEST DIF procedure for CATs, called CATSIB. CATSIB matches test takers on estimated ability based on unidimensional item response theory. To control for impact-induced Type I…

An important problem facing institutions of higher education is the number of students reporting that they are not adequately prepared for the difficulty of college-level courses. To meet this problem, a computerized adaptive testing package was developed that permitted remote placement testing of high school students via the World Wide Web. The…

This publication presents guidelines for parents and educators in making appropriate decisions about participation in the Massachusetts Comprehensive Assessment System (MACS) tests for students with disabilities, and it describes commonly used test accommodations. State law requires the participation in MCAS of all students who are educated with…

This manual presents information and instructions for test administrators in administering the 1998-99 version of the writing session of the Maine Educational Assessment (MEA). Sections of the manual present a checklist for test administrators; changes and reminders to the MEA for 1998-99; responsibilities of test administrators (scheduling,…

This manual presents information and instructions for principals and test coordinators in administering the 1998-99 version of the writing session of the Maine Educational Assessment (MEA). Sections of the manual present a checklist for principals/test coordinators; changes and reminders to the MEA for 1998-99; instructions for test coordinators…

A computerized adaptive test (CAT) administration usually requires a large supply of items with accurately estimated psychometric properties, such as item response theory (IRT) parameter estimates, to ensure the precision of examinee ability estimation. However, an estimated IRT model of a given item in any given pool does not always correctly…

College admissions tests provide a standardized and objective measure of student achievement and generalized skills. Unlike high school grades or rank, admission tests are a common measure for comparing students who have attended different high schools, completed different courses, received different grades in courses taught by different teachers,…

This paper focuses on a version of sequential mastery testing (i.e., classifying students as a master/nonmaster or continuing testing and administering another item or testlet) in which response behavior is modeled by a multidimensional item response theory (IRT) model. First, a general theoretical framework is outlined that is based on a…

This document focuses on assessment portfolios and examines the advantages and challenges of using an assessment portfolio system inclusive of English language learners as a district-wide assessment tool. Advantages of including English language learners in the assessment program include increased school accountability for all students, a shared…

Discusses concerns relating to the preparation of internal and external practical examinations in microbiology at the university degree or diploma level. Outlines the basic objectives, initial organization, and major considerations in preparing the laboratory examination. (JR)

Authors describe a measurement technique which processes item data so as to indicate logical relationships among items. (HB)
