Tennessee residency program trains new teachers and combats shortages

As the nation deals with severe teacher shortages, a new Tennessee residency program could be a potential solution to the crisis. The first-of-it-kind program allows teaching candidates to work full-time in the classroom while pursuing their degree — a win for future teachers and schools.

One of those teachers is Demetrius Winn, who works at Kenwood Middle School, an hour north of Nashville. Two years ago, the 42-year-old father of four spent his days mopping floors as a school custodian.

"It's definitely been a change," Winn told CBS News correspondent Meg Oliver.
