This study aims to investigate the extent of teachers' satisfaction with principals' demonstrations of instructional leadership practices in credited primary schools in Egypt (Asyut) and excellent primary schools in Kuwait. A total of 346 participants selected through stratified random sampling, 185 from Egypt (Asyut) and 161 from Kuwait, completed a questionnaire scored on a 4-point Likert scale. The results support the proposed hypothesis that both countries share more common features of school instructional leadership than they hold differences as it confirmed that principals in both countries were actively involved in practising instructional leadership in seven domains. However, principals in Egypt (Asyut) showed slightly higher mean scores than those in Kuwait for most survey items. The study recommends that concepts such as ‘decentralization of school administration', ‘collaborative practice', and “instructional leadership", need to be adopted in both countries. The study recommends the improvement of school principals' current practices of instructional leadership.
