This paper describes the Multiple Assessment Programs and Services (MAPS) Placement Research Service. Students entering nonselective colleges show a wide range of ability. The College Board offers these colleges a number of tests of reading, writing, and mathematics skills for use in placing students appropriately. The MAPS Placement Research Service is a new service available to colleges that use these tests. The service analyzes test score and criterion data supplied by the college and produces a report based on the data. The college can use the information to establish decision rules for placing students into courses or to counsel individual students in their selection of courses. The MAP Placement Research Service report consists entirely of tables, is organized by groups of students, and includes the score distributions of all predictors and criteria and the intercorrelations of all predictors and criteria in each group of students. The user can request a series of detailed analyses of the relationship between particular predictors and criteria. For each analysis, the user specifies the group of students, the predictor or predictors, and the criterion measure. Tables, smoothing procedures, and sample sizes are discussed. A sample MAPS Placement Research Service Report is appended. (PN)
