The following study explored the relationship between trust and collaboration in one Northeastern suburban district. In sum, 122 teachers responded to a trust and a collaboration survey. We hypothesized that the level of trust would be correlated with the level of collaboration. Bivariate and canonical correlations were used to analyze the findings. This study confirmed that trust in the principal was correlated with collaboration with the principal and that trust in colleagues was correlated with collaboration with colleagues. However, trust in clients (students and parents) was not correlated with collaboration with parents. The set of trust variables together explained 71% of the variance in the collaboration variables, with trust in clients being the most significant variable in predicting teacher-teacher collaboration. Collaboration with colleagues was the most potent of the collaboration variables. These findings suggest the importance of establishing a culture of trust in fostering collaboration between teachers. More research is needed to understand the complexities involved with parent collaboration. (Contains 3 tables.)
