Almost half of Detroit district schools don’t have a gym teacher. Next year, that may change.

Since 10-year-old Hezekiah Haynesworth moved to his new school in the Detroit district, he’s always up out of his seat, talking to classmates and getting into trouble.

His mother, Victoria, says he wasn’t always like this. She believes he has nowhere to burn off excess energy because Bagley Elementary doesn’t offer students enough time for gym class or recess.

Bagley Elementary is one of 50 schools in the district without a gym teacher. Out of the 106 schools in the district, only 56 have at least one certified, full-time physical education teacher, according to data obtained by Chalkbeat.

The district employs 68 certified full-time physical education teachers for its student population of 50,875. More than 15,000 Detroit schoolchildren attend a school without a full time physical education teacher.

In Michigan, there are no laws requiring schools to offer recess. As for physical education, schools are required to offer the class, but the amount of time isn’t specified, which means some kids, like Hezekiah, might only go once a month or less.

“He’s had behavior issues, but if he had the gym time there’s different activities he would do to burn off energy,” she said. “They would get that anxiety and fidgetiness out of them.”

Haynesworth might get her wish. Superintendent Nikolai Vitti announced earlier this month that there’s money in the budget to put gym teachers back in schools, along with art and music teachers and guidance counselors next school year, though the budget plan has not yet been approved.

“Not every student is provided an opportunity for physical education or gym” right now, Vitti said at a meeting earlier this month.

The district has almost 200 teacher vacancies, and giving schools money for a gym teacher doesn’t mean a school will be able to hire one.

But Vitti said he has several efforts in the works, like more recruiting trips and better hiring practices, to address the difficulties of finding and bringing in new employees.

Detroit is not the only district that has cut back on physical education teachers in recent years. At a time when schools are heavily judged by how well students perform on math and reading exams, some schools have focused their resources on core subjects, cutting back on the arts and gym and cutting recess to make more time for instruction and test prep. But experts say that approach is short-sighted.

Research on the importance of physical activity in schools has reached a consensus — physical education improves children’s focus and makes them better students.

“Available evidence suggests that mathematics and reading are the academic topics that are most influenced by physical activity,” according to a 2013 federal report.

The link between physical education and improved reading is especially important for the Detroit district. Educators are working in high gear, in part pushed by Vitti, to prepare for the state’s tough new law that will go into effect in 2020, requiring third-graders who don’t read at grade level to be held back.

This year, the Michigan Department of Education has started to include data on physical education in schools into its school scoring system, which allows parents to compare schools. A separate score for physical education might push schools to hire physical education teachers.

Whether the state’s new emphasis on gym class or Vitti’s proposal to place a gym teacher in each district school is enough to put physical activity back in the schools is unclear, but Hezekiah’s mom Victoria desperately hopes it happens.

Hezekiah is given 45 minutes to each lunch, and if he finishes early, he’s allowed to run with the other children who finished early. If he doesn’t eat quickly enough to play, Victoria says she can expect a call about his disruptive behavior.

“I used to think that my son was just a problem — that it was just my problem,” she said. “But it’s a system problem. They don’t have the components they should have in the school.”
