eating, dressing, elimination, and hygiene as an 
adult, although an  extended period of teaching and 
time is needed for the individual to become indepen-
dent in these areas, and reminders may be needed. 
Similarly, participation in all household tasks can be 
achieved by adulthood, although an extended 
period of teaching is ne eded, and ongoing supports 
will typically occur for adult-level performance. 
Independent employment in jobs that require lim-
ited conceptual and communication skills can be 
achieved, but considerable support from co-work-
ers, supervisors, and others is needed to manage 
social expectations, job co mplexities, and ancillary 
responsibilities such as scheduling, transportation, 
health benefits, and mone y management. A variety 
of recreational skills can be developed. These typi-
cally require additional  supports and learning 
opportunities over an ex tended period of time. 
Maladaptive behavior is present in a significant 
minority and causes  social problems.TABLE 1 Severity levels for intellectual disability (intellectual developmental disorder) (continued)
