"In the midst of the confusion about how to best measure teacher efficacy, an unpublished measure used by Bandura in his work on teacher efficacy has begun quietly circulating. Bandura (1997) pointed out that teachers’ sense of efficacy is not necessarily uniform across the many different types of tasks teachers are asked to perform, nor across different subject matter. In response, he constructed a 30-item instrument with seven subscales: efficacy to influence decision making, efficacy to influence school resources, instructional efficacy, disciplinary efficacy, efficacy to enlist parental involvement, efficacy to enlist community involvement, and efficacy to create a positive school climate. Each item is measured on a 9-point scale anchored with the notations: “nothing, very little, some influence, quite a bit, a great deal.” This measure attempts to provide a multi-faceted picture of teachers’ efficacy beliefs without becoming too narrow or specific. Unfortunately, reliability and validity information about the measure have not been available."
