Abstract:

The aim of this research is to develop a valid and reliable measurement tool that can measure the collaboration between stakeholders in schools. In the study, data were collected from two different groups for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to determine the construct validity of the scale. There are 600 teachers in the first study group and 960 teachers in the second study group. Participating teachers were selected by simple random sampling from those working at public primary school, secondary school and high school levels. The content validity of the research was provided in line with expert opinions. As a result of the analysis, a structure was obtained where the scale consisted of 38 items, explained 71.78% of the total variance, and the fit indices were at an acceptable level. Since the scale focuses on the level of collaboration between stakeholders in schools, the dimensions are named as "school principal-stakeholder collaboration", "teacher-colleague collaboration", "parent-teacher collaboration" and "school guidance service-stakeholder collaboration". The rotated factor load values of the items in the School Collaboration Scale ranged between .61 and .85. The item-total correlations ranged between .48 and .86. Cronbach's Alpha internal consistency coefficient for the 1st dimension is .96, the 2nd dimension is .95, the 3rd dimension is .94, and the 4th dimension is .95. The total Cronbach's Alpha value of the scale is .97. As a result of the analysis, it was concluded that the school collaboration scale developed is a valid and reliable measurement tool that can be used to measure the level of collaboration at all school levels.
