This report presents questionnaires that were used in three phases of a longitudinal study of career aspirations and attainments among low income youth and of their mothers' aspirations for them. The subjects were interviewed in 1969, when they were in the fifth and sixth grades, in 1975, and in 1979. Participants were members of three low income subcultures: rural white Applachians, rural Southern blacks, and Southern inner-city urban blacks. Also interviewed was a small sample of poor urban whites in one Southern state. An introduction describes the instruments and discusses the components studied, which included the following: (1) occupational and educational aspirations and expections; (2) significant others; (3) academic and achievement motivation; (4) self-concept; (5) child's perception of mother's degree of communication and independence training; (6) mother's behavior as perceived by the child; (7) IQ; (8) parental values--characteristics of children valued; (9) mother's achievement value orientation; (10) alienation or anomie; (11) locus of control; (12) family background and social particpation; (13) work experience, and job and salary history; (14) job search patterns and barriers; (15) importance of job aspects and job satisfaction; (16) educational attainment and barriers to aspired level; and (17) educational satisfaction and encouragement from parents.
