This study investigated the adult adjustment of a statewide random sample of 737 Iowa individuals with learning disabilities, 59 individuals labeled behaviorally disordered, and 142 individuals labeled mentally disabled, all graduates of special education resource teaching programs. Results are reported in terms of: (1) general status information, such as marital status and living arrangements; (2) information about those competitively employed, such as wages, hours worked per week, and percent of living expenses paid; and (3) comparison of competitively employed versus unemployed individuals, in terms of high school vocational training and work experiences. Information is also provided on the postsecondary education and training of those interviewed, as well as on overall"successful" adult adjustment. Data are compared across the three disability areas and across gender, where relevant. The study found that about 90% of the graduates in each disability area were single, and two-thirds were living with parents or relatives. The largest proportion of competitively employed persons was found within the learning-disabled group (77%), followed by the mentally disabled (62%) and the behaviorally disordered (58%).
