This article extends the work by Armstrong and Shi on CUmulative SUM (CUSUM) person-fit methodology. The authors present new theoretical considerations concerning the use of CUSUM person-fit statistics based on likelihood ratios for the purpose of detecting cheating and random guessing by individual test takers. According to the Neyman-Pearson…

Computers can offer valuable assistance in the development and administration of personalized tests. This article provides an overview of different types of conventional and personalized tests and explores computerized adaptive testing. Also proposes a specific methodology for managing diagnostic adaptive tests and a hypertext system (HyperDelfi)…

Computerized adaptive testing allows us to create a unique personalized test that matches the ability and knowledge of the test taker. (Author)

Discusses computerized adaptive testing, which is designed to provide students with an individualized examination adjusted to their skill levels. Indicates that scores are derived by comparing correct answers with the answers' difficulty rating. Highlights the advantages and disadvantages of the system and provides guidelines for successful…

A description is provided of the experiences of three community colleges in implementing computerized adaptive testing to assess the entry-level skills of students. Chapter 1 provides background information on the project, which utilized The College Board's Computerized Placement Tests (CPT's), a battery of untimed, individualized tests of reading…

Discusses the future of computerized adaptive testing (CAT), i.e., experimental tests developed by the Educational Testing Service in response to criticism of the Standardized Aptitude Tests (SATs). CAT examinations are individually tailored to each test taker, and researchers believe they are more predictive than conventional SATs. (JJD)

This paper presents an explanation of the program design of the three separate Pascal-language programs which comprise UCLA's Diagnostic Testing Package "DX." The three parts of the DX test package are three closely interrelated programs--Editest, Runtest, and Summary. Editest serves the following functions: (1) the creation of a…

This paper describes a computer program in Microsoft BASIC which selects and administers test items from a small item bank. The level of the difficulty of the item selected depends on the test taker's previous response. This adaptive system is based on the Rasch model. The Rasch model uses a unit of measurement based on the logarithm of the…
