This study considers the use of repeaters when test equating. The subjects consist of five groups of applicants to a professional certification program. Each group comprises first time examinees and repeaters. The procedures include a common item linear equating with nonrandom groups, use of equating chains, and the use of total examinee group…

This study was designed to illustrate the use of the Rasch model procedure to equate the Dade County Compensatory Education Skills Test (DCCEST) to the State Student Assessment Test (SSAT) for both mathematics skills and communications skills. The SSAT was a test developed by the Florida State Department of Education to measure students' level of…

The current New Jersey high school graduation law requires that students pass a ninth grade test in reading, writing, and mathematics. Equating the writing test from year to year to be sure that passing scores remain identical, regardless of the test form administered, requires developing a scoring technique. A research study was developed based…

This paper examines how various equating methods are affected by: (1) sampling error; (2) sample characteristics; and (3) characteristics of anchor test items. It reviews empirical studies that investigated the invariance of equating transformations, and it discusses empirical and simulation studies that focus on how the properties of anchor tests…

This paper focuses on the questions which arise as test practitioners monitor score scales derived from latent trait theory. Large scale assessment programs are dynamic and constantly challenge the assumptions and limits of latent trait models. Even though testing programs evolve, test scores must remain reliable indicators of progress.…

A technical advisory committee assisted the Alabama State Department of Education in establishing passing scores and equating test forms of the Alabama High School Graduation Examination (AHSGE). The committee examined four methods of setting cutting scores: (1) Jensen's theoretical method--probability theory is used to set standards that are…
