A more thorough explanation:

An accredited law school is an institution that provides formal legal education and training. The standard program usually lasts for three years, and graduates receive a Juris Doctor degree. In order to take the bar examination in all states except California, one must graduate from an accredited law school.

Accreditation is granted by either the state and the Association of American Law Schools or the state and the American Bar Association. This ensures that the law school meets certain standards and provides a quality legal education.

For example, if a student wants to become a lawyer in New York, they must graduate from an accredited law school in order to take the bar examination. This means that the law school they attend has been approved by the state and either the Association of American Law Schools or the American Bar Association.
