Enacted by Congress in August 1977 to provide employment and training opportunities for youth and to provide for other improvements in employment and training programs, this act is cited as the Youth Employment and Demonstration Projects Act of 1977. It has three titles. Title I--Young Adult Conservation Corps--amends the Comprehensive Employment and Training Act of 1973 by adding this title to establish the corps to provide employment and other benefits to youths who would not otherwise be currently productively employed, through a period of service during which they engage in useful conservation work and assist in completing other projects of a public nature on federal and nonfederal public lands and waters. Title II--Youth Employment Demonstration Programs--amends Title II of the Comprehensive Employment and Training Act of 1973 by adding a part C to establish a variety of employment, training, and demonstration programs to explore methods of dealing with structural unemployment problems of the nation's youth. Subparts cover youth incentive entitlement pilot projects, youth community conservation and improvement projects, and youth employment and training programs. Title III contains miscellaneous provisions including transfer of funds and waivers of fund limitations. (JT)
