Development of Curriculum Practices Proficiency Scale for School Principals: A Study of Validity and Reliability

Abstract

The main aim of this study is to test the construct validity of the scale of school principals' self-efficacy perceptions in managing curriculum implementation through confirmatory factor analysis (CFA). The study group consisted of 297 school principals working in primary, secondary and high schools affiliated to Trabzon Provincial Directorate of National Education. The data of the study were obtained by using the Self-Efficacy Perceptions of Managing Curriculum Implementation Scale. In the CFA analysis conducted to test the scale structure, χ2/sd ratio was calculated as 1.68; RMSEA: 0.05; SRMR: 0.04; IFI: 0.95; TLI: 0.94; CFI: 0.95; GFI: 0.88; AGFI: 0.86; RMR: 0.02. These values indicate an acceptable fit. Cronbach Alpha value for the entire scale was measured as 0.94. Alpha value indicates that the reliability level of the scale is high. The Confirmatory Factor Analyses suggest that the scale assessing school principals' perceptions of self-efficacy in managing curriculum implementation, comprising 28 items across 4 factors, demonstrates construct validity.
