This study was conducted to examine the preparation of principals to deal with incompetent or marginal teachers. There is some concern that principals may not be current on effective teaching techniques, may not have sufficient time during the day to deal with management demands as well as teacher observation and assistance, and may not have sufficient resources available from the school district for training/retraining. It is also a concern that administrative certification programs may not provide adequate training in appropriate methods of evaluation and conferencing; consequently, stress may be created when an administrator deals with an unsatisfactory teacher. A survey created for this study using "The Administrative Attitudes Toward Unsatisfactory Teachers" instrument, was administered to 722 elementary and secondary public school principals in Pennsylvania. According to survey results, principals perceive that they use sound instructional leadership practices; report that they are fairly effective in dealing with unsatisfactory teachers; do not experience a great deal of psychological stress in dealing with unsatisfactory teachers; and find time management, supportive resources, and administrative certification programs are major problems. Four tables are appended. (Author/LL)
