Five yet-to-be determined high schools across New Jersey will be experimenting with later start times.

Gov. Phil Murphy signed a law Friday, requiring the schools to start after 8:30 a.m.

The move follows years of debates for later high school start times.

Advocates cited major health benefits for teens.

The five schools taking part in the experiment are not yet known, as the law requires the state to select at least one urban, suburban and rural high school from different regions.
