Administrators must be knowledgeable in curriculum and instruction, must be skillful in data gathering and analysis, must be able to set goals, must be skillful in conducting effective conferences, must have team building skills and conflict resolution skills, and must have mentoring and coaching skills.   The Advancing Educational Leadership (AEL) training addresses all of these skills and provides practical tools for participants to implement.  This 3 day, researched based and engaging training is now required for teacher appraisers who are T-TESS evaluators unless you are already ILD certified.
