2014 LET Performance of Schools in the Philippines: An Analysis of Roughness

Abstract

This paper presents an analysis of roughness of the performance of the Teacher Education Institutions (TEIs) in the Philippines in the August 2014 Licensure Examination for Teachers (LET). The scores in the 2014 LET of the TEIs in the Philippines exhibit roughness based on the results of the histograms and the fractal spectra.  The histograms show that the behavior of the scores of the takers in the elementary and secondary levels are more or less the same as they bend more on the lower scores. A comparison between the two sets of scores revealed that examinees in the elementary level performed better than the secondary level. The fractal spectral analyses affirm that there is greater variability in the higher scores and uniformity in the lower scores. The fractal spectra show the heavy-tailed processes of the fractal dimensions that indicate self-similarity properties of the percentage of scores both in the elementary and secondary levels. Self-similarity property of the 2014 LET scores is evident in the lower scores, and the behavior is consistent to both the elementary and secondary levels in the 2014 LET performance of schools. The variations in the performance of the TEIs in the 2014 LET can be attributed to some factors inherent to the schools’ characteristics like the selection, admission, and retention policies and accreditation status.
