ABSTRACT

Objective: In education, the notion of competence has become central during the last four decades. The existing competence questionnaires for school principals are extremely limited. Despite the small number of available questionnaires, the particular one used by Kelly Glodt in Kansas in the USA in 2006 in order to determine the school principals’ perceived competence level in common administrative roles is considered a convenient, adequate and valid instrument. The aim of this study is to conduct an Exploratory Factor Analysis to the previously adapted, validated and applied Greek version of this questionnaire in order to identify a certain amount of sub-scales concerning the perceived competence level of elementary school principals and vice-principals in common administrative roles.
Rationale of the study: The identification of a certain amount of sub-scales could facilitate our future effort to extract findings regarding the comparison between the perceived competence level of elementary school principals and vice-principals in common administrative roles and some of their personality traits. The factors that will come up may result in outlining and preparing a full programme of professional development.
Methodology: During the preliminary analysis, we examine the correlations among items, the factorability of the particular dataset via the Bartlett’s test of sphericity and the sampling adequacy on the basis of the Kaiser – Meyer – Olkin (KMO) measure. We perform an exploratory factor analysis by applying Principal Component Analysis with Varimax rotation in order to rotate the factor solution to a more interpretable structure.
Results: The preliminary analysis shows that all items correlate significantly with all others (p<0.001) and none of the correlation coefficients are particularly large (more than 0.9); the values of the correlation coefficients range from 0.541 to 0.781. The procedure of the statistical analysis leads to the selection of a five-factor model with overall explained variance equal to 63%. During the procedure of extracting factors, there are eight items that are deleted. The communalities of the remaining items range from 0.516 to 0.811 with a mean of 0.63 and a standard deviation of 0.075. The reliability analysis shows that all factors are reliable, since the Cronbach’s Alpha is above 0.70 for all factors. Finally, the correlations between each item and the total score of the corresponding factor range from 0.569 to 0.824.
Conclusions – Discussion: We conduct an Exploratory Factor Analysis on the Greek version of the Principals’ Perception of Competence Survey (PPCS) questionnaire to identify any possible sub-scales. The study revealed that a five-factor model is proposed so that it can be used in order to compare this questionnaire with some others in the future.
