The Leadership Excellence Achievement Plan (LEAP) presented here is a way for principals to improve leadership ability with an emphasis on evaluation. It first recommends formulating a precise definition of the principal's job divided into three areas: technical competencies, administrative skills, and performance goals. Among the technical competencies listed as typical are providing instructional leadership, visiting classes, and preparing the school budget. The twelve areas of administrative skills considered appropriate include problem analysis, judgment, organizational ability, and decisiveness. Performance goals to achieve specific outcomes are to be established by the principal. The next step suggested is for the principal and the principal's immediate supervisor to draw up a work plan--a "development plan" (if job performance is already satisfactory) or an "improvement plan" (if job performance is not satisfactory). The progress review is recommended to monitor how things are going midyear. For the final assessment it is suggested that the most defensible report form would combine rating scales and narrative assessments. The report includes examples of step-by-step procedures on a time-line and typical evaluation forms to show how LEAP might operate. (Author/JM)
