A framework to address issues in collaboration between public schools and higher education is developed in this report. The relationships among social conditions and motivations are discussed, specifically, how the four social conditions are related to the five motivational factors and the "liability of newness." Four collaborative models based on the "liability of newness" framework are described: time allocation, incidental collaboration, joint governance, and consortium center. A conclusion is that the nature of a cooperative relationship depends on specific goals. The concluding section relates the framework and motivations to the four collaborative models, discusses specifics of the models in relationship to the four factors of "liability of newness," and relates 10 principles for collaboration from the literature to motivational conditions. Four figures are included. (31 references) (LMI)
