Post-Behavioral Science is one of the approaches to educational administration. Building of the strengths and shortcomings of the past, three powerful, interrelated concepts of school improvement, democratic community, and social justice emerge(Murphy, 2002), which form the development of the next era of the profession: the post-behavioral science era. This view is reinforced with increased emphasis on emergent nontraditional perspectives(variously labeled neo-Marxist, critical theory, and postmodernism).
