Regarding the impact of the study variables, the results have showed that there is no statistical significance between the means of the sample estimations on the five dimensions that could be attributed to the gender, experience, and the number of training courses. There is a statistical significant at the level (0,5) between the sample estimations means that is attributed to educational region variable in the motivation dimension, After studying the literature of administration practices in light of emotional intelligence and after obtaining with the results of the field study, the current study suggested a number of recommendations and the most important is the necessity to conduct training courses and programs for school principals that contain skills of administration practices in light of emotional intelligence. It is also needed to conduct meetings and educational forums to raise principal awareness about emotional intelligence concept and the importance for the principals to possess emotional intelligence skills at work. It is also important to evaluate the employees in general and the school principals in particular on the basis of self-competency through their awareness of emotional intelligence skills and to what extent they implement these skills rather than evaluating them on their academic achievements.
