At what age can a person be tried as an adult?

In Massachusetts, the legal age at which a person can be tried as an adult in criminal cases is 18 years old. This means individuals who are 18 years or older are subject to the adult criminal justice system rather than juvenile court. While a 17-year-old may face certain legal ramifications or charges that could lead to adult court proceedings, they are still considered a minor under the law until they turn 18. Therefore, the correct response aligns with the statutory framework that defines the transition from juvenile to adult jurisdiction in the Commonwealth. Understanding this distinction is crucial for professionals working in psychology and law, highlighting the complexities of juvenile justice and the age of majority.
