The six tables in this report rank the combinations of reading materials used in the classrooms of 34 elementary schools of Washington, D.C., during the 1976-77 academic year. The data are based on teacher reports about first through sixth grade students for whom there were both pretest and posttest scores. The tables indicate that a wide variety of combinations of materials were used in teaching students to read at each grade level. While the basal reader was the predominant material used, the variety of combinations of particular materials suggests much individualization. (RL)
