This study sought to provide data regarding the use of infusion of gerontological materials throughout curriculums to enhance students' attitudes toward older adults, their knowledge of aging-related issues, and their perceptions of gerontological social work. A quasi-experimental design was used to compare outcomes for graduate social work students who were and those who were not exposed to gerontological infusion. Results indicated that exposed students experienced a greater improvement in their view of aging-related career opportunities and in their belief in the importance of gerontological social work. Treatment group students also showed greater gains in self-rated aging knowledge. Both treatment and control group students had significant gains in a test of aging-related knowledge. Pedagogical implications are discussed.
