The Responsibility for Student Achievement Questionnaire (RSA) was designed to measure elementary or secondary school teachers' beliefs regarding their responsibility for their students' academic successes and failures. The 30 items were constructed in the alternative-weighting format; for each item describing student success or failure, the respondent assigns one number indicating the degree to which that event is caused by the teacher, and a second number indicating the degree to which the event is caused by factors outside the teacher's control. (Both numbers must total 100). The RSA was administered to 215 elementary and secondary school teachers who also indicated the grade level taught, number of years of teaching experience, and sex. Results showed that females assumed greater responsibility for the positive achievements of their students than males did. Differences related to years of experience or grade level taught were not significant. Test reliability was moderately high, and subscale scores assessing responsibility for success and for failure were distinct. (The similarity between teachers' RSA scores and students' Intellectual Achievement Responsibility Questionnaire scores is discussed, and the RSA questionnaire is included). (Author/GDC)
