Last fall, a top Denver Public Schools administrator sent an email to 10 secondary principals asking that high schools and sixth-12th grade campuses push their start times later this year—to 8 a.m.
It would have meant changes at many of the city’s secondary schools, most of which start between 7:15 and 7:45 a.m.
But most students and parents shouldn’t expect to see any schedule shifts this fall. Only one of the schools that received the email—Denver Center for International Studies-Baker—changed its start time, moving from 7:25 to 7:55 a.m.
A handful of Denver high schools, including the new Northfield High, Manual High and DSST charter high schools, also have start times of 8 a.m. or later this year, but such schedules were either already in place or planned prior to the email request.
While district administrators say there was never any mandate to push back start times at other schools, the email appears to be more than a casual suggestion.
Fred McDowell, the district’s former instructional superintendent for high schools, wrote in the email, “The data indicates a direct correlation to student levels of alertness and engagement. Therefore we are asking all high schools and 6-12 campuses to institute a start time of 8am beginning in the 2015-16 school year.”
Towards the end of the email, he wrote, “There will be ongoing discussion in order to work out the logistics and support needed to operationalize this across DPS (Food Services, Transportation, Athletics, After school Activities, and etc).”
The email went to principals at most of the district’s traditional high schools on Nov. 14. (See the full email at the end of this story.)
Nine months later, it appears miscommunication between top administrators and logistical obstacles stymied the late start proposal. McDowell resigned at the end of the school year and took a job in the School District of Philadelphia. He could not be reached for comment.
Greta Martinez, assistant superintendent for post-secondary readiness and McDowell’s supervisor, said the email miscommunicated the district’s intention, which was to launch conversations about later start times, not change to them this year.
Asked why McDowell sent the message, she said, “Fred’s not here so I can’t ask him. It’s all in interpretation. I can’t guess what he was intending with his message.”
Why are later start times better for teens?
- Sleep-wake cycles shift during puberty, making it hard for kids to fall asleep as early as they did in elementary school.
- Experts say it’s normal for teens to stay awake till 11 p.m.
- It’s recommended that teens get 8.5-9.5 hours of sleep a night.
- Research shows that students with early bell times get less sleep than they should, which is tied to lower achievement and higher rates of obesity, depression and car accidents.
Suzanne Morris-Sherer, principal of Thomas Jefferson High School, said she believes later start times are a great idea but aren’t currently feasible because of transportation constraints and sports schedules.
When she received McDowell’s email last fall, she forwarded it to her staff and asked for feedback to provide to central administrators. About a half-dozen staff members responded, most concerned about the issues she cited.
Morris-Sherer said she didn’t recall any follow-up from central administrators afterwards.
The debate about later start times in DPS and elsewhere is nothing new. But with recent calls for change from national health experts and some of DPS’s own leaders, the inertia is striking. It’s possible these kind of proposals may hold even less sway moving forward given the district’s embrace of decentralized decision-making, which gives principals’ significant autonomy for making building-level decisions.
Scott Mendelsberg, McDowell’s replacement, addressed the issue of decentralization, saying, “It wasn’t really about, ‘We don’t have to do what they’re asking.’ I think principals thought it would be an okay idea, but really did worry about the logistics of this.”
“It’s a little surprising that more didn’t go to this model, but I don’t think it’s a dead issue.”
Martinez agreed, saying there will be further conversations about moving start times with even more schools involved than the 10 targeted by McDowell’s email.
“I think we just needed a little better messaging about what this means and what this looks like,” said Mendelsberg.
The early side of late
While the 8 a.m start time McDowell requested last fall would have moved district high schools in the right direction according to research, it wouldn’t have gone as far as experts recommend.
A policy statement released by the American Academy of Pediatrics last fall recommended start times of 8:30 a.m. for middle and high schools. And in 2002, the Colorado PTA passed a resolution urging state and federal legislation for 9 a.m. secondary start times.
Cindy Daisley, the group’s president and the mother of two North High School graduates, said even 13 years later, it’s still a big issue.
“I would love to see something happen districtwide, even statewide, because I think it’s important for our teenagers to perform better,” she said.
When her twin boys were in high school, she said, “getting them out of bed in the morning was so painful for all of us because they just required that much sleep.”
There’s science to back up her experience. It indicates that teens need 8.5-9.5 hours of sleep a night and are hardwired to favor later bedtimes.
The American Academy of Pediatrics’ policy statement on start times noted that teens who get enough sleep are at reduced risk of being overweight or suffering depression, are less likely to be involved in car accidents, and have better grades and higher standardized test scores.
Generally speaking, no one disputes the research on teen sleep habits and later school start times. The sticking point is putting it into practice.
So what makes it so hard to change high school start and end times?
One of the biggest issues is the transportation jigsaw puzzle. Because middle and elementary school bus routes usually follow early-morning and early-afternoon high school routes, changes to the high school schedule can impact schools all down the line.
Even in DPS, where few high schoolers use district buses, transportation still matters. In part, it’s because special education students do rely on yellow buses to get to high school, so moving their start times could mean fewer district buses available to transport younger children.
Morris-Sherer said even with the current 2:50 p.m. dismissal at Thomas Jefferson, her special education students often have to leave their last class early to make it to the school bus in time. She worried that with a later dismissal time, they’d miss even more of their last class.
“It would just impact my instructional day,” she said.
Later start and end times could also cause transportation woes for general education students. For example, city buses currently make stops on Thomas Jefferson’s campus twice after school lets out. If the dismissal time were delayed, Morris-Sherrer said those students could miss the two on-campus buses and be forced to walk across the bridge over Interstate 25 for a later and more inconvenient off-campus pick-up.
Scott Mendelsberg said such issues, which might involve negotiating different on-campus pick-up times with the city bus system, must be addressed at the district level, not left up to schools to handle.
“There are solutions to…some of these concerns,” he said.
The other major challenge in changing start and end times revolves around after-school obligations including school sports, after-school jobs or family responsibilities like caring for younger siblings.
At the 2,500-student East High School, student athletes sometimes miss half of their last class to get to games on time even with the current 7:30 a.m. to 2:45 p.m. schedule. Principal Andy Mendelsberg, who is Scott Mendelsberg’s brother, said a later dismissal would mean an even bigger dent in class time.
At Northfield High, where the school day runs from 8:45 a.m. to 4:45 p.m., Principal Avi Tropper said most games will be scheduled for 6 p.m. on weeknights or on Saturdays. For sports like cross-country, in which multi-school meets are often scheduled around 2 p.m., students may have to leave early, he said.
Andy Mendelsberg said with East fielding four teams in almost every sport and limited daylight in late fall, it would be impossible to eliminate weekday afternoon games.
“There’s no way for us to work around that…We can’t play everybody on Friday and Saturday and get through the season.”
The schools that make it work
While late high school start times are hardly the norm in Denver or Colorado as a whole, they do have a small presence.
Manual’s 8:10 a.m. start time has been in place for years, said secretary Carol Grant, who’s worked at three high schools during her 20-year career in DPS.
She believes the later start makes it easier for students to get to school on time and that they’re more awake once there.
When she worked at West High School, she said, “I’d write a thousand passes in the morning” for the long line of kids arriving late.
But Thomas Jefferson Principal Morris-Sherer said the school’s 7:30 a.m. start time is not a problem for most kids.
“I don’t have kids falling asleep habitually in class,” she said. “It is what it is. You just adjust your life.”
Andy Mendelsberg said East allowed students to opt for an 8:20 a.m. start several years ago as part of an experiment that added a ninth period to the school day. Only 31 students took advantage of the option.
At the four high school locations of the Denver School for Science and Technology, or DSST, start times range from 7:55 a.m to 8:15 a.m.
The later-than-average start times were intentional, said Andrew Mendrop, manager of communications and development for the charter school network.
The physiology of teenagers was a key consideration, but there were competing priorities, he said. Network leaders didn’t want to push start times back so much that it would inconvenience parents dropping their children off before work or students with after-school activities or jobs.
Last year, the Harrison School District near Colorado Springs pushed back start times at all 20 of its schools after a committee studied the issue for two years. High schools now start at 7:45 a.m. instead of 7:20 a.m, and elementary and middle schools now start at 8:35 a.m. instead of 8:10 a.m. (On Mondays only, middle schools start at 10:05 a.m. and high schools start at 9:15 a.m.)
Northfield has the latest start time among comprehensive high schools in Denver, but at least one Colorado district has even later starts.
Middle-schoolers in the Cortez-Montezuma district start their day at 8:50 a.m. and high-schoolers at 9 a.m.
Some Denver students may dream about reporting to school so late, but for now they’ll have to keep setting their alarms.
