Recommendations are offered to help administrators successfully implement mastery learning (ML). It is stated that: (1) ML requires watching both the achievement and satisfaction of learners; (2) consideration of teachers' knowledge and attitudes when training them in ML principles is critical; (3) a high level of skill and commitment is required of all involved administrators; (4) the administrative skills necessary for training teachers in ML are the same as the teaching skills necessary for working with children in the classroom. A 16-item checklist outlines desirable behaviors in three areas of administrator responsibility: staff development, instructional leadership, and school climate management. For each item, a desirable behavior is paired with an extreme example of an undesirable behavior. The emphases of the behaviors are: maintenance of an individualized model of staff development, making an effort as instructional leader to observe outcomes, and creating a school climate which provides for human resource development through caring behavior. It is suggested that the checklist first be used to rate the administrative staff as a whole, then to rate the individual. Scoring instructions for the checklist are given. (DC)
