Abstract:
The purpose of the study was to assess the contribution of supervisory development practices to
the effectiveness of supervision activities in primary schools of Ilu Aba Bor Zone. To achieve the
objectives, quantitative research method was employed. About 154 teachers, 10 basic teachers
association, and 10 cluster supervisors took part in the study. Quantitative data were gathered
through close ended questionnaire and analyzed using frequency, percentage, mean, standard
deviation, t-test, ANOV and linear regression It was revealed that the overall supervisory
development practices was weak in assigning proficient supervisor (M = 2.71, SD = 1.14), there
are no adequate supportive instruments (M = 2.55, SD = 0.86) that professionally support
supervisors. The effectiveness of supervisors in carrying out their role and function was lower
than average (in instructional development M = 2.65 SD = 0.80), curriculum development M =
2.96) and teachers development M =2.72 SD = 0.9). Supervisors are busy in administrative
routine activities and there is difference between teachers preference and supervisors
performance. Distance of schools from resource center, number of schools they serve, low level
of support from Woreda education office were among the major factor affecting effectiveness of
supervisors. It was concluded that unless professionally fit supervisors are in place to develop
both teachers and schools management; supervisors are free from challenges they face, quality
of education will remain in question. It was recommended that Woreda and zone education office
are advised to redesign supervisory development process, critically assess supervisors practice
on their work and provide adequate on job training.
