The purpose of this study was to examine the impact that perceived administrative support and stress had on special education teachers' self-efficacy. A survey was used to gather quantitative data from 244 special education teachers in Central California's Tulare and Fresno counties. Using correlation and regression analysis, this study found a significant relationship between perceived administrative support, stress, and teachers' self-efficacy. The findings suggest that administrative support is critical in maintaining teachers' self-efficacy and stress levels. Implications include developing policies to help administrators increase their capacity to support special education teachers.
