“…Many researchers have reported academic achievement levels in reading and mathematics among adolescents with learning disabilities that are consistently low, 3 to 5 years behind actual grade placement at entrance to ninth grade (see Cobb & Crump, 1984;Levin, et al, 1985;Norman & Zigmond, 1980;Schaloch et al, 1986;Thornton & Zigmond, 1987 a;Warner, Alley, Schumaker, Deshler, & Clark, 1980;Zigmond & Thornton, 1985). Unfortunately, students with learning disabilities do not seem to recoup these basic skill deficiencies during their years of attending secondary school resource room programs (Zigmond & Thornton, 1985;Gregory, Shanahan, & Walberg, 1986) and, in fact, the gap between achievement scores and grade expectancy level actually seems to widen as students with learning disabilities progress through high school (Norman & Zigmond, 1980;Warner, Alley, Schumaker, Deshler, & Clark, 1980).…”
