This study was initiated in 1964 under the sponsorship of the Cooperative Research Program of the Office of Education to develop and supply data useful to policy makers and planners of training programs for research, development, and diffusion personnel in education. The first task was the construction of a logical structure to account for the formally defined institutional roles, from which a picture of the research community in 1964 could be drawn and future demand projected. Chapter 2 provides a general description of the community in 1964, analyzing it by institutional settings and researchers' roles, estimating the actual number of researchers and the number being added to the community. Chapter 3 deals in detail with the procedures used, funding projections, and personnel projections. Chapter 4 considers the effects of curtailment of funds for ESEA Title IV research training programs which will reinforce the existing pattern rather than enable new centers for training and roles for researchers to be established. Finally an attempt is made to define the roles which could be expected to emerge under the new research, development, and diffusion funding programs, namely director and staff of outside-funded development programs, technical support personnel, development project personnel, training personnel, and stimulators and coordinators of activities. Eight appendixes give additional documentation. (MBM)
