The purpose of this correlation study was to identify a possible relationship between elementary teacher background in mathematics as measured by completed college math credit hours, district-provided professional development hours of training in Common Core math standards, and years of teaching experience, and teacher efficacy in math as measured by personal teaching self efficacy and outcome expectancy. The sample in the present study consisted of 69 elementary (K-5) math teachers in a medium-sized semi-rural district located within a southern state. The data was collected using the Mathematics Teaching Efficacy Beliefs Instrument (MTEBI), an online survey that was sent to the teachers through their district email. Additional questions were added to the survey to collect information about teacher background training. A non-parametric Kendall's Tau B analysis was conducted to assess the hypothesized relationship. A significant, positive relationship was found between years of teaching experience and teacher self efficacy, but not with outcome expectancy. Additionally, a significant, positive relationship was found between teacher self-efficacy and outcome expectancy. Results displayed no significant relationship between college credit hours or district-provided training hours with teacher self-efficacy or outcome expectancy.
