The purpose of this study was to examine the relationship between teacher religiosity and teacher self-efficacy. The present study builds upon previous research which has shown purposeful work in everyday living fosters intrinsic motivation, religious orientation affects daily living, and teacher self-efficacy beliefs predict student achievement. Religiosity and self-efficacy data were gathered from public school teachers from a suburban school district in North Texas and from private Christian schools in Western Washington. The Age Universal I-E scale (a measure of religious orientation intended to capture how one lives out his/her religiosity), Teachers' Sense of Efficacy Scale, and a teacher characteristic form were used to collect data. In a multiple regression analysis, independent variables included teacher age, gender, grade level taught, experience level, campus type (public or private religious), and teacher religious orientation (intrinsic or extrinsic); the dependent variable was the score for teacher self-efficacy. The regression analysis resulted in an equation that explained only slightly more than 9% of the variance in the score for teacher self-efficacy. Three significant variables were identified--grade level taught, teacher age, and intrinsic religious orientation. Teacher age and teacher intrinsic religious orientation were the two most important contributors according to a comparison of beta weights. Intrinsic religious orientation contributed to the equation, but it acted as a suppressor variable in the study, having little predictive value by itself but contributing to the predictive value of the model. Based on the data collected, recommendations for future research and suggestions for field application are offered.
