This thesis describes a research study that examined how collaborative reflective practice with three staff members in a middle years school affected their psychological constructs of what constitutes a good school. Using an action research design, the study made use of personal construct psychology and the methodology of repertory grid technique. Repertory grid results were analyzed using methods developed from personal construct theory (cluster analysis, principal components analysis and messy change grid analysis). This permitted insight into the nature and processes of changes that occurred. These processes were examined in light of Leithwood’s work on teacher development and Fullan’s thoughts on educational change. Using these models as an analytical framework, an evaluation was made of the potential uses and value of repertory grid technique in middle schools. The technique aligns well with the Leithwood and Fullan models and has notable benefits and advantages to offer the field of educational leadership.
