Intellectual Level Scale (ILS-19) for School Administrators: Validity and Reliability Study

Abstract

Background/purpose – In addition to many competencies of school administrators, the level of intellectuality can increase the commitment of educational actors to the organization in schools with sociocultural diversity, which is considered as a wealth of Turkey. Considering the sociocultural developments of the present day, it is important to know the intellectual level of school administrators. The aim of this research is to develop a valid and reliable scale to determine the intellectual level of school administrators.

Materials/methods – In the development of the Intellectual Level Scale (ILS-19), which consists of 19 items, 500 data were collected from teachers and analyzed using IBM’s SPSS statistical program. In this context, exploratory factor analysis (EFA) was conducted for construct validity and confirmatory factor analysis (CFA) for construct verification.

Results – According to the results of the exploratory factor analysis, the Eigen value of the scale consists of two subdimensions greater than one, and which was found to explain 66.743% of the total variance. The factor loading values of the scale items ranged from 0.610 to 0.864. According to the results of the confirmatory factor analysis, the chi-square value, AGFI (Adjusted Goodness-of-Fit Index), GFI (Goodness-of-Fit Index), NFI (Normed Fit Index), and RMSEA (Root Mean Square Error of Approximation) values of the model were found to be at an acceptable level, whilst the IFI (Incremental Fit Index) excellent and RMR (Root Mean Square Residual) values were found to be at an excellent level.

Conclusion – The developed Intellectual Level Scale is a measurement tool that can be used to determine the intellectual level of school administrators. Subject to adaptation, the scale may be applied as a measurement tool in studies to determine the intellectual level of any adult group.
