This research is an Arabian Gulf contribution to the "International Study of Principal Preparation" (ISPP). It compares the perspectives of Arabian school principals regarding their leadership preparation, drawing on three sets of data collected from Oman, Qatar, and Kuwait. Data were collected using the Arabic version of the ISPP survey. The investigation included adequacy of leadership preparation, problematic aspects of leadership, and prior leadership learning experiences. Quantitative analyses (descriptive statistics) were conducted to calculate percentages of agreement related to these aspects. Findings revealed interesting commonalities and differences between the three samples. The study concludes with suggestions for improving future leadership preparation provision.
