Start School Later Bloomfield, NJ

Bloomfield Public Schools · Bloomfield, New Jersey
Dear Superintendent Goncalves, Mr. Fleres, Principal Jennings, and Members of the Board of Education,
We are physicians and healthcare professionals writing to urge Bloomfield Public Schools to move Bloomfield High School's start time to no earlier than 8:30 a.m. This is the standard unanimously recommended by every major national medical authority, and a standard Bloomfield currently falls 45 minutes short of. We write not as advocates for a scheduling preference, but as clinicians who see the consequences of inadequate adolescent sleep in our practices and our community.
During puberty, adolescents undergo a well-documented, hormonally driven shift in their circadian rhythm. Sleep onset and natural wake times are delayed by two to three hours — not because of poor habits or device use, but because of neurobiological changes that cannot be voluntarily overridden. A teenager who cannot fall asleep before 11:00 p.m. and must wake at 6:00 a.m. for a 7:45 a.m. school day will consistently obtain six to seven hours of sleep — well below the eight to ten hours recommended for adolescents.
Chronic sleep deprivation in this range is not a minor inconvenience. It is associated with:
They are the documented, measurable outcomes of the schedule Bloomfield students currently operate under.
The medical community reached consensus on this issue more than a decade ago. Every major national health organization recommends that middle and high schools begin no earlier than 8:30 a.m.:
A 2019 consensus statement signed by more than 120 experts in medicine, sleep science, pediatrics, psychiatry, and public health described the evidence on early school start times as "unequivocal and extraordinarily consistent." A 2022 meta-analysis in Pediatrics journal, synthesizing data from 28 studies encompassing more than 1.7 million participants, confirmed that later start times produce longer sleep, lower sleepiness, and improved mood — and that 8:30–8:59 a.m. produces meaningfully better outcomes than 8:00–8:29 a.m.
Bloomfield High School's 7:45 a.m. start time is not a borderline case. It falls well outside the boundaries the medical community has defined. We stand firmly alongside the NJAAP Task Force letter, and we reinforce its recommendation without reservation.
We want to address directly one of the most common concerns raised against later start times: that athletic programs will suffer. The evidence points in precisely the opposite direction.
Sleep is the most powerful performance-enhancing resource available to a young athlete, at no cost. Research has consistently shown that improved sleep in adolescent athletes produces faster reaction times, greater accuracy, reduced injury rates, and faster recovery from training and competition. A landmark Stanford University study (2011) found that extending sleep among varsity athletes produced significantly faster sprint times and improved shooting accuracy. Ridgewood, NJ, which shifted its high school start time from 7:45 a.m. to 8:20 a.m., has reported stronger athletic outcomes since the change, not weaker ones.
Later start times do not hurt athletic programs. Sleep deprivation does.
Districts across New Jersey and the country have successfully implemented later start times while maintaining strong academic and extracurricular programs. Bloomfield's own middle school begins at 8:35 a.m., later than the high school. The logistical framework for a later high school start has been examined and modeled, and the NJAAP Task Force has offered to present implementation strategies from communities that have made this transition successfully.
Momentum at the state level reflects the same medical consensus. New Jersey Assembly Bill A3867, which would require middle and high schools statewide to start no earlier than 8:30 a.m., is advancing in the legislature. Bloomfield has an opportunity to lead ahead of that standard — to act on established evidence now rather than wait to be required to.
The question is not whether the science supports this change: it does, overwhelmingly.
We respectfully urge Bloomfield Public Schools to:
The students of Bloomfield High School deserve to learn at a time that does not compromise their health before the school day begins. We are available to support this district however we can, and we urge Bloomfield's leadership to meet this moment.
Respectfully submitted,
The undersigned physicians and healthcare professionals
