Abstract Consider any scoring procedure for determining whether an examinee knows the answer to a test item. Letx i = 1 if a correct decision is made about whether the examinee knows the ith item; otherwisex i = 0. Thek out ofn reliability of a test isρ k = Pr (Σx i ≥k). That is,ρ k is the probability of making at leastk correct decisions for a typical (randomly sampled) examinee. This paper proposes an approximation ofρ k that can be estimated with an answer-until-correct test. The paper also suggests a scoring procedure that might be used whenρ k is judged to be too small under a conventional scoring rule where it is decided an examinee knows if and only if the correct response is given.
