A competency based model of affective teaching is proposed for training teachers of students with Hispanic background in the southwestern United States. The GAC (generic affective competencies) model is described in terms of the adjustment needs of Hispanics in public school. Three competency clusters are outlined: creating the affective climate; managing conflicts, crises, and the classroom; and using positive classroom management practices. A brief study report confirms the validity of the GAC procedures. It is concluded that the GAC model is potentially significant in such areas as motivating students to achieve, rewarding students for correct responses and adaptive behavior, and modeling optional ways of coping with stress and managing social problems.
