This paper discusses the formation of collaborative high schools in Ohio and presents several incentives that the state's General Assembly might offer to encourage the formation of these schools. A collaborative high school is a high school shared and operated by two or more city, local, or exempted village-school districts. The report explores why some districts have been attracted to the collaborative high school option and why none have moved beyond preliminary discussions. The following questions guided this report: What is the history of inter-district collaboration in Ohio? How would a collaborative high school be structured, governed, and funded? What are the perceived advantages and disadvantages of forming a collaborative high school? and What strategies or incentives might encourage the development of collaborative high schools? Some inducements that might foster more collaborative schools include increased state support for collaborative facilities; the prioritization of Ohio School Facilities Commission funding for collaborative facilities; a competitive grant for districts that form a collaborative high school; increased basic aid for districts establishing a collaborative high school; and increased awareness of the collaborative high school option. Schools that received money to expand or replace facilities were less inclined to join in collaborative ventures. (Contains 11 references.) (RJM)
