STEM SPOTLIGHT

We did it, Spartans! Thanks to the incredible support of our STEM community, we raised more than $78,000 for the Accelerator Fund! 🎉

Every donation, share, registration, volunteer, and cheer helped make this year’s fundraiser an incredible success. Thank you for showing up for our students and our school!

On Thursday, September 10, members of our KOSON team attended an appeal hearing with the Colorado State Board of Education regarding the proposed relocation of STEM High School.

Following the hearing and the State Board’s decision, CEO Matt Cartier sent an update to STEM families on Friday evening with additional information and next steps.

In case you missed it, click below to read Mr. Cartier's message.

We’d love to hear from you! Our 2027–28 Academic Calendar Survey closes at 11:59 p.m. this evening. Please take a few minutes to carefully review the calendar options and select the option you believe would work best for your family.

Please note: The survey is limited to one entry per person and will require you to log in before submitting your response.

Some families have reported experiencing issues when attempting to log in on a mobile device. Our IT Department is aware of the issue and has been working to identify a solution. In the meantime, families who have experienced the survey freezing on a mobile device have had success accessing it from a desktop or laptop computer instead.

We appreciate your patience and, most importantly, we’d love your feedback! Your input is an important part of this process and will help us better understand the priorities and needs of our STEM community.

Don’t forget—the survey closes tonight at 11:59 p.m.!

Important information regarding upcoming testing for students in grades 6–12, including schedule adjustments and late-start information, was sent to Secondary families on Friday.

If you missed the communication, please take a few minutes to review the important message from our Testing Coordinator linked below so your family is prepared for the upcoming testing days.
