Peer reviewedPlake, Barbara S.; Impara, James C. – Educational Assessment, 2001
Examined the reliability and accuracy of item performance estimates from an Angoff standard setting application with 29 panelists on 1 year and 30 in the next year. Results provide evidence that item performance estimates were both reasonable and reliable. Discusses factors that might have influenced the results. (SLD)

Judgmental standard setting methods, such as the W. H. Angoff (1971) method, use item performance estimates as the basis for determining the minimum passing score (MPS). Therefore, the accuracy of these item performance estimates is crucial to the validity of the resulting MPS. Recent researchers, (L. A. Shephard 1994; J. Impara, 1997) have called…

Impara, James C.; Plake, Barbara S.; Hertzog, Melody; Giraud, Gerald; Spies, Robert – 1998
Judgmental standard setting approaches rely on the perceptions of experts about examinee performance on a test. Traditional standard setting methods ask panelists to estimate how well a randomly selected hypothetical examinee who is representative of a well-defined target group, usually a minimally competent candidate (MCC), will perform on each…

Buckendahl, Chad W.; Impara, James C.; Plake, Barbara S. – 2000
Many states use a statewide assessment strategy to evaluate districts on common measures. Because districts in Nebraska are not measured on common instruments, comparisons of district performance are difficult. The accountability model described in this paper contains three components related to school district performance on academic content…

Judgmental standard setting approaches rely on the perceptions of experts about examinee performance on a test. Traditional standard setting methods ask panelists to predict the probability that a randomly selected, hypothetical minimally competent candidate (MCC) will correctly answer test questions. Item performance predictions are difficult for…

Buckendahl, Chad W.; Impara, James C.; Plake, Barbara S. – 2000
Because districts in Nebraska are not measured on common instruments, comparisons are difficult. This study examined a district evaluation strategy that classifies districts into school performance ratings (SPR) based on a combination of three factors. Student performance and non-cognitive indicator data for three grade levels and two content…
