- Summary:
-
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 versus first-timers only. The failure of the results to show uniformly and substantially more accurate equating under use of only first-time (nonrepeater) examinees casts doubt upon the practice of routinely excluding repeater examinees in deriving equating functions for this testing program. The overall pattern of results does appear to favor slightly the use of first-timers. But the relative accuracy of equating with first-timers versus total group also appears to depend partly on the specific equating method (Tucker Equally Reliable versus Levine Equally Reliable). Further research is needed to determine whether eliminating larger proportions of repeaters produces differences greater than those found. (PN)
