What age must the onset of intellectual disability occur by to qualify for services?

To qualify for services related to intellectual disability, it is essential that the onset of the disability occurs before the individual's 22nd birthday. This time frame is established in order to ensure that those who are experiencing developmental challenges during their formative years receive the assistance they need throughout their transition to adulthood.

The rationale behind this age cutoff is rooted in the understanding that early intervention can dramatically affect long-term outcomes for individuals with intellectual disabilities. Services are designed to address developmental needs that are most pronounced in childhood and adolescence, which is critical for educational and social integration. After the age of 22, individuals are typically considered adults, and the support systems may shift or change, which is why the focus on earlier onset is pivotal for accessing the necessary resources.
