This report describes a study conducted in response to a request for help in establishing decision rules for exempting prospective teachers from a proposed statewide testing requirement in Indiana. Having decided to use Scholastic Assessment Test (SAT) scores as a basis for exempting prospective teachers from the Pre-Professional Skills Test (PPST), the Indiana Professional Standards Board had to decide how high a score to require on each portion of the SAT as a condition for granting exemption. Data were obtained for nearly 35,000 examinees who took the PPST and the SAT. The statistical technique used to estimate the conditional probabilities was logistic regression. The estimated conditional probability of passing PPST reading and mathematics scores for prospective teachers with SAT verbal and mathematics scores ranging from 300 to 700 was determined. These probabilities are presented in table form. (SLD)
