What is the maximum age at which juvenile jurisdiction can be retained?

Juvenile jurisdiction typically applies to individuals who commit offenses prior to reaching a certain age, which is often set at 18 in many jurisdictions. However, some states allow for an extension of juvenile jurisdiction, allowing individuals to remain under juvenile court control until they reach age 21 or even higher, depending on the specific laws of that state.

Thus, the correct answer recognizes that while 18 is a common age limit for juvenile jurisdiction, many systems extend this limit to 20, 22, or even beyond. In this case, the maximum age of 22 reflects jurisdictions that have made provisions for young adults who still need support and services tailored toward their developmental needs, acknowledging that maturity can take longer for some individuals. This extension implies a focus on rehabilitation rather than punishment, aligning with the juvenile justice system's goals.

Understanding this maximum age is crucial for juvenile probation officers, as it influences their responsibilities and the resources available to the youth they supervise. The other options suggest different limits which may not align with the latest policies in juvenile justice, especially in states with a higher retention age.
