The purpose of this study was to determine the validity of school and district dropout data and, if possible, to establish an accurate dropout rate for the Dade County Public Schools. Several key school files and documents were examined; prior dropout data were examined; and a survey of school personnel was conducted. The general conclusion of the study was that, given (1) the current state definition of a dropout, (2) the existing district procedures for defining dropouts and calculating dropout rates, and (3) the extent to which staffs at some schools are knowledgeable of and correctly follow these procedures, there is reason to question the accuracy of the district's and schools' dropout data. Further, the extensiveness of the problems in these three areas is such that determining an accurate dropout rate would not, at this time, be feasible. Specifically, the resources that would be required to produce accurate data would be better spent in revising existing definitions and procedures, developing computer programs to monitor and summarize school-level data, and providing inservice programs to schools' clerical and administrative staff regarding the revised definitions and procedures.
