The purpose of this study was to investigate the relationship between teacher efficacy levels and fifth grade Virginia SOL Mathematic achievement. This study sought to determine the extent to which personal efficacy, general efficacy, and total efficacy account for fifth grade Virginia Standards of Learning Mathematic achievement over and above that explained by teacher experience, teacher education, and class size. A critical review of the previous research methodologies and findings on teacher efficacy demonstrated the need for further research in this area. This study hoped to provide school officials in educational leadership with data necessary to plan professional development to improve classroom instruction, teacher efficacy, and student achievement. This study utilized a quantitative survey which measured personal, general, and total efficacy levels among fifth grade teachers in 11 elementary schools located in central Virginia. Twenty-one of the 27 (78%) 5th grade teachers that were surveyed, completed and returned the survey used in the study. Other data, such as teacher education, teacher experience, class size, and student achievement scores were collected from the division with the permission of the division's superintendent.
