This study employed multiple regression modeling to examine the success of 63 California elementary schools in terms of (a) school-community social capital, (b) student academic performance, (c) student behavioral incident rate, and (d) teacher turnover rate with respect to the extent of school-community partnership programs. Also of interest to this study was whether the impact of school-community partnership programs on school success varied with respect to selected control variables, which included (1) teacher experience, and (2) school social economic status. Findings suggested the number of 5-year partnerships in a school were positively associated with (a) increased school-community social capital and (b) increased student academic performance, although this association decreased when control variables were entered into the regression. However even when all control variables were entered into the regressions, "effective" partnerships of parent/community involvement was found to be significantly associated with (a) increased school-community social capital, (b) increased student academic performance, and (c) decreased teacher turnover rates. These results indicate that that school-community partnerships build school-community social capital, strengthen family, school, and community ties, and promote norms that improve the school environment, which supports increased student achievement and decreased teacher turnover. The study's findings have potential benefits for educational reform efforts, demonstrate how social capital may be developed in elementary school settings, and offer further validation of both social capital theory and the Community School Model.
