Welcome to Start School Later
Southeastern PA (RASNC)!
The SSL Southeastern PA Chapter represents the schools and communities that are part of the Regional Adolescent Sleep Needs Coalition (RASNC) of Southeastern PA. Formed in March of 2016, the mission of RASNC is to raise awareness of the nationally identified public health issue of chronic adolescent sleep deprivation and promote optimum teen sleep health. A major area of our focus is supporting school districts as they explore adopting “healthy school hours" for all students as per the recommendations of multiple national medical organizations such as the American Academy of Pediatrics and the American Medical Association.
We provide resources, guidance, support and networking opportunities for school communities who wish to explore making change.
Our Coalition has had representation from over 35 School Districts across six PA counties, multiple Leagues of Women Voters (LWV), Intermediate Units, and other PA SSL Chapters. We have recently expanded to include interested stakeholders from New Jersey and Delaware. Participants include: School Board Members, School Administrators, Teachers, Students, Health Professionals, Parents, LWV Members and other concerned citizens.
We welcome you to join us
Is a Move to Permanent Daylight Savings Time Good or Bad
for Public Safety and Health?
March 2022: US Senate passes the Sunshine Protection Act making Daylight Savings Time permanent.
Start School Later OPPOSES the Sunshine Protection Act
and SUPPORTS Permanent Standard Time instead.
and SUPPORTS Permanent Standard Time instead.
Start School Later and many medical organizations and public health experts concur, based on medical research,
that seasonal time changes are detrimental to public health and safety.
HOWEVER, the solution is NOT permanent daylight savings time.
that seasonal time changes are detrimental to public health and safety.
HOWEVER, the solution is NOT permanent daylight savings time.
“Daylight saving time increases our morning exposure to darkness and evening exposure to sunlight, the most powerful timing cue for the human body clock,” said Dr. Shannon Sullivan, chair of the American Academy of Sleep Medicine Public Safety Committee and clinical professor of sleep medicine at Stanford University School of Medicine. “The time change causes misalignment between the body’s daily rhythm and the clock, making it harder to fall asleep at night, disrupting sleep quality, and leading to sleep loss which can negatively impact health and safety. DST results in more darkness in the morning hours, and more light in the evening hours. Adopting permanent DST also would undo the benefits of delaying start times for middle schools and high schools.”
Start School Later opposes Permanent Daylight Savings Time and supports Permanent Standard Time.
Here are position statements and research from organizations such as the American Academy of Sleep Medicine and others that inform the Start School Later position:
- Ditching the daylight saving time change for better sleep, health and safety (AASM)
- Daylight saving time: an American Academy of Sleep Medicine position statement (JCSM)

- End Daylight Saving Time and Restore Permanent Standard Time Nationwide (Resistbot)
- Daylight Saving is a Trap (The Atlantic)
- How daylight savings time poses a host of health concerns, according to a neurologist (PBS)
US Legislation: Standard Time vs Daylight Savings Time
- The U.S. tried permanent daylight savings time in the 1970's then quickly rejected it (NPR)
- House Leaders want to take up Daylight Savings Time Bill - Later (The Hill)
- In a blink of an eye, Senate passes time-change bill with no dissent (The Washington Post)
- Some Senators Want Permanent Daylight Saving Time (NPR)
- Some Senators Introduce a Bill to Make Daylight Savings Time Permanent (CNN)

Managing Adolescent Sleep in a Pandemic Culture
Survey: Reflections on Healthy School Start Times During Stay-At-Home Orders
The Regional Adolescent Sleep Needs Coalition created a brief survey to ascertain sleep patterns and school schedules during the Spring/Summer 2020 stay-at-home orders. The survey was completed by parents or guardians of students who were in grades 6-12 during the 2019/2020 school year. Click on the file below to download the summary of the survey findings.

PA School Start Times Study Resolution Report
Sleep Deprivation in Adolescents: The Case for Delaying Secondary School Start Times
The report is in response to Senate Resolution 417 of 2018 Sleep Deprivation in Adolescents: The Case for Delaying Secondary School Start Times. The Pennsylvania Senate unanimously approved the resolution and directed the Joint State Government Commission to establish an advisory committee to conduct a study of issues, benefits and options related to instituting a later start time to the school day in secondary schools.
Adolescent Sleep Health Research Studies and Articles
FACT: Teens need about 8 to 10 hours of sleep each night to function best. Most teens do not get enough sleep — one study found that only 15% reported sleeping 8 1/2 hours on school nights. Biological sleep patterns shift toward later times for both sleeping and waking during adolescence -- meaning it is natural to not be able to fall asleep before 11:00 pm. (National Sleep Foundation - Teens and Sleep)
NOTE: Research featured has been used by school districts in Pennsylvania investigating sleep health and school start times

Student Sleep Survey Instrument Examples
Sleep researchers advise school districts to seriously consider administering a validated student sleep survey to their adolescent students for two important reasons. One is to get a research documented assessment of the true state of sleep among their students. The second is to use that resulting data as a baseline measure against which to measure the effectiveness of any sleep interventions the school district initiates.

Bedtime Calculator & Healthy Hours
Medical organizations, like the American Academy of Pediatrics, “urges middle and high schools to aim for start times that allow students to receive 8.5 to 9.5 hours of sleep a night. In most cases, this will mean a school start time of 8:30 a.m. or later”.
Use the National Sleep Foundation Bedtime Calculator to find out what time to go to bed or wake up for your sleep health.
