“…The results include updated rankings of special education departments and a multiple regression model identifying doctoral program characteristics that are closely linked to the rankings. Examples of these program characteristics are faculty performance, such as research productivity (Conrad 8c Blackburn, 1985;Cox 8c Catt, 1977;Drew, 1975;Drew 8c Karpf, 1981;Guba 8c Clark, 1978;Hagstrom, 1971;Jones et al, 1982;King 8c Wolfle, 1987;Knudsen 8c Vaughn, 1969;Saunier, 1985;Tan, 1990); outcome measures, such as number of graduates, (Astin 8c Henson, 1977;Conrad 8c Blackburn, 1985;Elton 8c Rodgers, 1971;Elton & Rose, 1972;Jones et al, 1982;Solmon & Astin, 1981); and institutional and departmental characteristics, such as specialization and faculty inbreeding (Cartter, 1966;Conrad & Blackburn, 1985;Glower, 1980;Jones et al, 1982;Solmon 8c Astin, 1981).…”
