In the context of personnel selection it is usual that psychological tests are employed for dichotomous classifications of applicants. In such cases, the conventional reliability coefficients, designed to estimate score reliability, are not suitable for estimating the accuracy of classifications. This paper introduces the Phi(Lambda) coefficient developed by Brennan and Kane (1977) in the framework of Generalizability Theory (Brennan, 2001) for estimating the reliability of a cutting point. In addition, a free software was developed to facilitate the estimation of the coefficient and its use is demonstrated through an empirical example, using a recruitment test.
