A vital part of successful schools is the well being of school staff. Yet burnout and depression are common and many fail to thrive in the profession they entered with great hope, dedication and commitment. Teacher distress can lead to low morale which in turn undermines teaching effectiveness. Despite the important role of schools in the healthy development of youth, there has been little research into how schools can create a supportive climate, reduce teacher stress, and increase their effectiveness. Reducing Teacher Stress and Building a More Effective School Culture will study one promising approach that addresses the problem of staff distress with the implementation and evaluation of a program of Acceptance and Commitment Training (ACT).
