For over 50 years, school leadership preparation and development has been a priority in the United States; however, since the turn of the century, school systems, universities, and professional associations around the world have become more interested in developing programs to prepare aspiring school leaders and support newly appointed and experienced principals. This increased global attention to leadership development has arisen because public or government school leaders are being held accountable for improving student learning outcomes for an increasingly diverse set of learners. Because school leadership studies have been dominated by American researchers, global program providers tend to rely on Western perspectives, concepts, and theories, which may not accurately reflect local and national cultural norms and values. As such, calls for expanding research studies in non-Western societies are increasing. Despite relying on Western-based leadership concepts, leadership preparation programs outside the United States differ substantially. Cultural norms and values, infrastructure support, and social and economic conditions influence the availability and types of programs afforded to aspiring and practicing school leaders. As a result, there is a continuum of leadership development systems that range from: (a) mandatory, highly regulated, and well-resourced comprehensive programs for preservice qualification, induction for newly appointed principals, and in-service for practicing school leaders to (b) non-mandatory, minimally regulated, and moderately resourced programs to determine eligibility for positions and induction to the role to (c) non-mandatory, poorly regulated, and under-resourced programs, which are offered infrequently, require long distance travel, and participants costs are not covered.
