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