Abstract:
The three southern border provinces are seen as the areas of local identity. Education
administration should be therefore implemented in accordance with their lifestyle, culture, tradition and
cultural diversity. In order to upgrade learning achievement, teachers performance is significant for
educational management. The aim of this research was to study factors affecting the competency of
teachers in bilingual schools in the three southern border provinces. The samples were 146 bilingual
teachers. Simple random sampling was employed to select the samples. Questionnaires of factors
affecting the competency of teachers were used as the instrument. Statistics used in this research were
mean, standard deviation and multiple regression. The results were as follows: The factors which could
predict the core competency with the statistic significance at .05 were teacher-student relationships (X
3),teachers academic performance (X5) and teachers motivation (X2) whereas attitudes towards teacherprofession (X1) and teachersmorale (X4) were not statistically significant. Effectiveness of all factors in
prediction of the core competency was 74.20 (Adjust r-square=.742).The factors which could predict the functional competency with the statistic significance at .05 were teachers academic performance (X5),teacher-student relationships (X3) and teachers motivation (X2) whereas teachers morale (X4) and attitudes towards teacher profession (X1) were not statistically significant. Effectiveness of all factors inprediction of the functional competency was 67.20 (Adjust r- square =.672).
