(PKPM) An Excel program developed to assist researchers in the determination and presentation of confidence intervals around commonly used score reliability coefficients is described. The software includes programs to determine confidence intervals for Cronbach’s alpha, Pearson r–based coefficients such as those used in test-retest and alternate forms situations, split-half, and Cohen’s 2 × 2 unweighted Kappa. The general basis for the confidence interval computations and the program features are presented. Availability, at no cost, and conditions of use are described.
