In honor of our very first graduating class, our amazing librarian Gretchen gathered graduation photos from our incredible staff to put on display! 🎓

Some of these photos are a little more recent than others 😜 but every cap, gown, hairstyle, and fashion choice represents an important stepping stone in the journey that built our Sage Family. ❤️

From graduates to educators, mentors, and leaders…we’re proud to celebrate the experiences that brought us all here. Congratulations again to the Class of 2026! 🎉

Our first graduating class is all grown up and ready to get those diplomas at Sage International Middleton’s very first graduation ceremony tomorrow night. Where does the time go? Congrats Class of 2026!

Middleton Diploma Program students completed their

Middleton Diploma Program students completed their community Creativity, Activity and Service (CAS) project to benefit the Idaho Humane Society. The Junior class, with the guidance and support of their CAS Coordinator Georgia Thies, raised over $200 dollars for the Idaho Humane Society through a community bake sale, and engaged younger students to make animal enrichment toys that were then donated.

The DP students celebrated their service with a trip to the Idaho Humane Society to cuddle some bunnies and learn how they can continue to advocate for animals in need. 🐰

Big thanks to the @idahohumanesociety for being an amazing partner and helping our students learn more about how to think and act local. ❤️
