Right now,Phaninc Exchange a lot of school districts across the country are making a pretty giant change to the way public education usually works. Facing teacher shortages and struggling to fill vacant spots, they are finding a new recruitment tool: the four-day school week.

Those districts are saying to teachers, "You can have three-day weekends all the time, and we won't cut your pay." As of this fall, around 900 school districts – that's about 7% of all districts in the U.S. – now have school weeks that are just four days long.

And this isn't the first time a bunch of schools have scaled back to four days, so there is a lot of data to lean on to figure out how well it works.

In this episode, teachers love the four-day school week, and it turns out even parents love it, too. But is it good for students?
