ScoreAllcalculates the item response theory maximum-likelihood and Bayesian scores for tests administered by paper-and-pencil. The output from ScoreAll contains the number-correct score, simple formula score, Bayesian-modal and maximum-likelihood ability estimates, and EAP Bayesian ability estimate for each examinee. Requires both examinee response data and a, b, and c item parameters as input. ScoreAll is ideal for testing programs that administer tests via paper and pencil, and score using IRT.
