This report documents the fifth year of follow-up of mentally retarded school completers in the Pittsburgh (Pennsylvania) area, begun with parents/ guardians of students who completed their special education programs in 1985-86 (N=73) and in 1986-87 (N=60), 1990 (N=102), and in 1991 continued with completers (N=95), when a preliminary follow-up study was done. Findings for the first two groups are reported in terms of living arrangements, work situations, competitive employment, physical and emotional disabilities, expectations and outcomes (a retrospective), and the hard core idle. The 1990 cohort is discussed in terms of living arrangements, work situations, competitive employment, training and placement, transition planning and outcomes, and comparison of work and living arrangements of three cohorts 1 year after completion. Initial follow-up data for the 1991 school completers are presented for living arrangements, work situations, job placements, post-school training placements, transition planning, and comparison with the 1990 cohort. Conclusions on the oldest group include more movement into a variety of competitive and sheltered work situations, entrenched patterns of idleness by 14 percent of the group, and no progress for those with multiple disabilities. Conclusions for the 1990 cohort include substantial similarities with experiences of the older group at the same stage. Findings for the 1991 cohort included a higher proportion with no work placement. (DB)
