The pamphlets included in this volume are technical reports prepared as outgrowths of the Student Information Systems of the Western Nevada Regional Education Center (WN-REC) funded by a Title III (Elementary and Secondary Education Act) grant.

Pamphlets included in the volume are Student Placement in Mathematics Based on Previous Achievement, Overage Students and Students in Lowest Quartile, Using Student Data from Computer Printouts, Using Student Entry Data and Standardized Test Data, Secondary Courses Offered in the WN-REC Region, and Predicting Stanford Achievement Scores (National Percentiles) from Student Marks.
