As we consider future school calendar options, we want to ensure that any decision we make reflects the needs of our families, students, and staff. Your input is an important part of this process, and we value the perspectives of our entire STEM community.

We ask that you take a few minutes to carefully review each of the calendar options provided in the survey and consider what would work best for your family. Each option has different benefits and considerations, and your thoughtful feedback will help us better understand the priorities and needs of our community.

Thank you for taking the time to share your perspective and for partnering with us as we work to make an informed decision that best supports our students, families, and staff.

Please complete the Parent Calendar Survey and select the option that you believe is best for your family.

We know our STEM parents and families want to be involved, and we love having you on campus! Our Elementary School currently has several volunteer opportunities open and ready for families to sign up.

Lunchroom Volunteers: Help our students during lunch by opening drinks and packages, assisting with cleanup, helping keep the lunchroom running smoothly, and lending an extra hand where needed.

Driveline Volunteers: Help our staff safely welcome students from their vehicles to the building in the morning or help students get from the building to their vehicles during afternoon dismissal.

Whether you can volunteer once or become a familiar face around campus, we’d love to have you join us! Use the button below to view available opportunities and sign up.

Our Boosterthon Accelerator Fund Color Party is almost here! Get ready for an afternoon filled with color, music, fun, and plenty of Spartan spirit! 💙💛

Secondary Event Day Schedule

Our goal is to hold four Color Party sessions to give students plenty of room to celebrate! Four sessions will be held if we have enough students qualify to participate by raising the minimum $25 donation.

If participation supports four sessions:
1–1:25 p.m. | High School Color Party
1:35–2 p.m. | High School Color Party
2:15–2:40 p.m. | Middle School Color Party
2:55–3:20 p.m. | Middle School Color Party

If we do not have enough students qualify for four sessions:
1:35–2 p.m. | High School Color Party
2:55–3:20 p.m. | Middle School Color Party

📍 Location: Secondary Playfield

Students who have raised the $25 minimum will be able to participate in the Color Party during their scheduled time. Students will run, dance, move, and celebrate while being showered with color throughout the event!

A Few Event Day Reminders

Color powder can get into eyes, noses, mouths, hair, and clothing. Students with sensory sensitivities are encouraged to bring goggles, a mask, or other protective items that will help make the experience comfortable. Students may also choose to stay toward the side of the event where there is less exposure to color.

Want to Volunteer?

We would love to have parents join us and help make the Color Party a success! Volunteers will help throw color at designated times, keep students organized, and bring lots of energy to the celebration.

Bonus: If you have a battery-powered leaf blower, bring it along with a fully charged battery! We’ll use them to help blow excess color off students before they head back inside.

If you would like to volunteer during the Secondary Color Party, sign up using the link below.
