Therefore, it is recommended that the Regional Education Bureau and the Woreda Education Offices should conduct training needs analysis on principal’s trainings, targeting at identifying the natures of the previous trainings; experience of the training participants, the skill gaps, and training needs; to make the training programs need based and attract interested participants.]]>
