This booklet describes a junior high school reading laboratory located in Urbana (Illinois) Junior High School, Fisher Campus. The student population in the school numbers approximately 950. Students have individual schedules, with six instructional classes of fifty minutes per day. Students enrolled in the lab attend each day for a regular fifty-minute period. The lab is an elective for all students and in all but a few cases does not supplant the regular English classes. Instruction is individualized, prescriptive, and effective. Both remedial and developmental contracts are prepared for each student. The basis for this prescription is the Stanford Diagnostic Reading Test. The mean expected increase in reading achievement as measured by this test after two semesters in the lab is one year and three months. However, nearly 50% of the students in the lab may be expected to show an increase of one year or more each semester, with gains of 3-5 years per semester for some students. These data are consistent from year to year. (TS)
