Minimizing the Impact of Snow Days   

Seattle Public Schools and Seattle Education Association are working together to explore using technology so students can continue to learn from home during inclement weather/snow days.

Minimizing the Impact of Snow Days   

Seattle Public Schools and Seattle Education Association are working on innovative solutions that will minimize the possibility of extending the 2022-23 school year into July, while still meeting the state-required 180 days of student-centered learning.

Together, we are exploring using technology so students can continue to learn from home during inclement weather/snow days. 

We cannot predict or control the weather, but we can maximize our response to it. Every SPS student has access to a laptop or an iPad along with options for internet access. This means we now have a proven way to engage with students even when snow or other extreme weather makes it unsafe to go to school buildings.

Approval and Planning School Year Dates

The school calendar is developed collaboratively with SEA and the dates are agreed upon in the Collective Bargaining Agreement (CBA). The formula to schedule key dates in the CBA states that the first day of school will be the first Wednesday of September.

The key dates formula was originally bargained in the 2015-18 CBA as a tool for staff and families so there would be consistency around calendars and dates weren’t arbitrarily set.

During the 2019 bargaining period, multiple joint workgroups between SPS and SEA were established, with one specifically organized to address inclusive considerations related to religious and cultural observations and practices. This workgroup developed supplemental materials and guidance to go along with the traditional school year calendar.

While not all religious/cultural events can be accommodated for, this guidance was created to serve as a reference for schools, families, and communities to be aware of potential schedule conflicts and excused absences and/or to make appropriate accommodations and supports for students and families on days of religious/cultural observances.

The religious and cultural observances identified in both the 2021-22 and 2022-23 Religion and Religious Accommodations documents, also highlights observances and traditions which involve fasting, which may have an impact on students’ abilities to perform at their highest level or be a reason for an absence from class.
