Research studies for use in planning, administering, and improving the in-school, summer, and out-of-school programs of the Neighborhood Youth Corps (NYC) were reviewed. Findings were analyzed from those studies that surveyed individual NYC projects or specific elements and those that attempted to develop and test ways to solve problems. Some major conclusions were: (1) NYC researchers and enrollees believe that the program has been beneficial to underpriviledged yough, (2) Although NYC gives students a chance to avoid another failure, it does not generally provide needed remedial education and counseling, (3) Job placement and development are not integral parts of most of the projects studied, (4) The out-of-school projects in urban areas are not reaching impoverished white youth in proportion to their numbers, and (5) Although participation in out-of-school programs reduces rate of arrests, youth are not equipped for jobs that pay enough to make criminal activity less attractive. Abstracts of 12 research studies are included. (SB)
