Cal. Education Code § 51430

(a) Notwithstanding any other law, a high school district, unified school district, county office of education, or the governing body of a charter school may retroactively grant a high school diploma to a person who has not received a high school diploma if they meet any of the following conditions: (1) The person was interned by order of the federal government during World War II and was enrolled in a high school operated by the school district or under the jurisdiction of the county office of education immediately preceding their internment and did not receive a high school diploma because their education was interrupted due to their internment during World War II. (2) The person is a veteran of World War II, the Korean War, or the Vietnam War; was honorably discharged from their military service; was enrolled in a high school operated by the school district or under the jurisdiction of the county office of education immediately preceding their military service in those wars; and did not receive a high school diploma because their education was interrupted due to their military service in those wars.

In making an evaluation as to whether to award a high school diploma to a pupil who meets the conditions of this paragraph, a school district, county office of education, or charter school shall consider any coursework that may have been completed by the pupil outside of the United States or that may have been completed by the pupil through online or virtual courses.
