Our paper discusses the need for continued focus on ethical leadership and the importance and benefits of ethical leadership development. We propose integrating ethical leadership development, that uses cognitive development theory, into the Center for Creative Leadership's Assess, Challenge, and Support (ACS) leader development model to help address the continued failures of ethical leader development. Our extended framework includes values and morals as a component of the model, and ethical organizational culture as its backdrop, thereby incorporating an examination of ethical leadership into each component of the ACS model. We conclude with practical implications and suggestions for future research.
