The North Carolina Advancement School was funded by the State of North Carolina in 1967 and charged with the task of conducting research into the causes of underachievement, and experimenting with approaches for its remediation. This is the sixth in the series of research reports. The subjects of the study were sixth-graders who participated in the residential and instructional program during 1969 and 1970. The results of various tests and evaluations show that students attending the 1969 fall term did not evidence the positive gains on achievement, attitudes, self-concepts, and achievement responsibility that were observed for the 1970 spring group. Underachievers had lower self-concepts, more negative views toward home, school, and teachers, and assumed less responsibility for their learning than "typical" students. Various recommendations are presented on what research needs to be done in the future. [For related reports, see ED 045 761-765, and UD 011 486.] (Author/JW)
