To determine the occupational experiences of poorly educated disabled persons, 389 disabled adults serviced by a New York City private employment agency between 1960 and 1967 were interviewed. Each was medically able to work full-time, though vocationally handicapped due to his disability, and had fewer than 12 years of schooling. An index of vocational achievement, constructed to measure ability to function in the work situation with maximum rewards, included measures of employment status, changes in salary, and changes in job level since placement. Results at followup showed the following factors associated with vocational achievement: sex (men more successful than women), age (young more successful), and socioeconomic status (upper class more successful). Disability factors associated with achievement were onset of disability before age 45 and having a disability free from stigma. Work-related factors were interest in skilled manual jobs, high pay, avoiding formal job-seeking since placement, no specific job requirements when seeking last job, holding skilled manual positions, lengthy on-the-job training, and need to work as indicated by number of dependents.
