The Dimensionality of Teacher Collegiality and the Development of Teacher Collegiality Scale

This paper reports on the development of a teacher collegiality scale (TCS) which was validated using a sample of public secondary school teachers in Pakistan. The TCS measures seven dimensions of collegiality: Demonstrating mutual support and trust; observing one another teaching; joint planning and assessment; sharing ideas and expertise; teaching each other; developing curriculum together; and sharing resources. The initial 66 item scale was refined using both exploratory and confirmatory factor analyses. Exploratory factor analysis (EFA) was applied to data from a sample of 118 public secondary school teachers from six schools in Karachi and Lahore. To further validate the scale, confirmatory factor analysis (CFA) was applied to a sample of 364 public secondary school teachers from 17 schools in Islamabad. Based on the CFA results, the scale’s items were modified. Analyses found that the 7-dimension scale consisting of 32-items was appropriate for measuring teacher collegiality among Pakistani school teachers. The reliability coefficients of the TCS dimensions ranged from .71 to .85.
