This research study reports on the effectiveness with which the New Educational Program (NEP), a modification and refinement of the Job Corps Programmed Learning System, can provide effective learning experiences for underachieving adolescents and adults in various settings, including two juvenile detention facilities, a ninth grade class of underachievers, an MDTA skills center, and two out-of-school Neighborhood Youth Corps Programs (NYC). Program achievement is measured by achievement tests, quality of participation, and other outcomes indicative of achievement. The results vary depending upon the site, but some significant measure of success is achieved in all sites. One the average, students gain 9 grades in reading and 7 grades in math during their first three months. The best results are reported from one of the NYC programs in which the gain is 1.9 grades in reading and 2.12 in math after nine months' participation. About 45 percent of the students in the NYC program either use NEP credits to gain a high school diploma, or have passed the GED while enrolled in this program. This project is found to be an effective educational component in a variety of programs concerned with academic underachievers. The curriculum changes made based on experience in the unmodified NEP version are found to increase the NEP's effectiveness. (AUthor/AM)
