The League of Schools in southeast Idaho described in this report is a staff development consortium consisting of 15 local school districts, the College of Education, and the College of Liberal Arts at Idaho State University. Initiated in the belief that the ongoing training needs of classroom teachers could best be addressed by a coalition of trainers and practitioners working as a team to deal with common concerns, the League develops and maintains a permanent regional system of cooperative inservice planning, delivery, and evaluation. Districts are provided with technical assistance in all areas of staff development (e.g., long range planning, training of personnel, and program management). Resources are pooled for staff development purposes. This program is an effective vehicle that yields benefits for all members in shared resources and talents. It works because of the constant contact with the field. Activities are developed to meet specific needs, and deliberate efforts are made to help teachers determine needs. Services in technical assistance and organization of plans for activities are largely provided by a League inservice coordinator who has staff development responsibilities in each of the institutions. The League concept addresses not only staff development but also the large issues of school/university cooperation, structural relationships, and inter-institutional responsibility.
