The Educator’s Supplement is a professional development resource which can be effectively used by current and aspiring leaders to increase leadership capacity in extraordinary organizations. For each Law of Leadership, this resource includes The Principles of the Law, Questions for Further Review , an Action Plan , and a Self-Evaluation . Another useful item in the supplement is the Crosswalk Document combining the Interstate School Leaders Licensure Consortium (ISLLC) Standards for School Leaders with The 21 Irrefutable Laws of Leadership . Lastly, this Educator’s Supplement includes a Leader Evaluation Instrument with suggested Conference Questions . The Educator’s Supplement is a professional development resource suitable for use with individuals, pairs, small groups, and large groups. Throughout the development of this project, several leaders experienced success using the resource to model life-long learning, to initiate critical thinking regarding school leadership, and to encourage and facilitate enthusiastic and passionate discussion. Other leaders have experienced success using this resource to develop individual growth and professional development plans by connecting the Action Plans in each law to the ISLLC Standards for School Leaders. Each Action Plan includes measurable objectives which can be given a timeframe for follow-up to enhance a leader’s growth and development. The resources within the Educator’s Supplement can be used together or separately, depending on the needs of the organization.
