In some settings, the reliability of test scores must be approximated even though no examine has taken the complete instrument. Rather, one group of individuals has taken one fraction of the items, a second independent group has taken a different, non overlapping fraction of the items, and so on. Ultimately, a representative sample of examiness will take the complete test, but at the time when the estimate of reliablity to required, no such sample is available. Formulas are developed in this article to cope with these situation. The choice of one formula over another is contingent on the degree of similarity between or among the part - tests. Different estimator are developed for past - tests that are judged to be classically parallel, tau - equivalent or congeneric. Standards are proposed for differentiating among these three models for the part - tests.
