An integral part of Title I of the Elementary and Secondary Education Act programs has been the evaluation of these programs in terms of attainment of increments of gain in reading and mathematics. One of the most widely used methods of analyzing pre and post test norm referenced data has been the six-step historical regression procedure. This procedure compares the rate of growth of children within a Title I program with the predicted rate of growth they would have achieved without the Title I program. This predicted rate of growth is based upon the students' previous rate which is established by a grade equivalent score on a norm referenced test. The first five steps of the procedure demonstrate how to calculate, for a given student with a grade equivalent score, a predicted score after a certain number of months (usually between six and ten). The tables which comprise this document offer a shortcut way of calculating predicted scores and thus allow the evaluator to avoid the tedious task of calculating predicted scores for each youngster in the program. Limitations to using the tables are given. (RC)
