This seminar, sponsored by the Oregon Council for Continued Professional Development and the Oregon Department of Education, brought together 60 educational leaders from all sectors and from all regions of Oregon to discuss staff development issues. Fostering collaborartion between elementary/secondary and postsecondary institutions was a central theme. The proceedings are divided into four parts corresponding to the four study areas of the seminar: (1) guiding principles and assumptions regarding staff development, (2) school-based staff development, (3) a state-wide support system, and (4) a plan of action for implementing collaborative staff development support systems. Each part begins with a summary of the background readings and the presentation made at the seminar. This is followed by a summary of the participants' reactions to the statements about staff development. Each summary statement has three parts: the reaction statement, a tally of the "agree-disagee" ratings of the participants, and a summary of their written reactions and comments. An epilogue summarizes areas of agreement and includes reactions by the editors. (TE)
