7-10 Grades at UCA Band Clinic

Nearly 100 musicians from schools in our Upper Columbia Conference and Alaska Conference met for band clinic at Upper Columbia Academy Jan. 30 - Feb. 1. TCAS was one of the largest schools in attendance, bringing 34 band members. A big heartfelt thank you to the staff and parents for chaperoning our large group. If you missed out on the performance, you can watch online here!

Penny War

Thanks to everyone for supporting our Penny War. The kids had a great time and we were able to raise money for both the TCAS Mission Trip to Taiwan and Real Restoration – a Christian organization that rescues girls from human trafficking and then works to educate, heal, and restore their lives. Combined we raised $1400 so GOOD JOB EVERYONE! The 3rd & 4th Grade classroom generated the most points per student so
they will be receiving a special treat for the entire classroom after Christmas Vacation.

Veterans Day

We celebrated the service of our veterans on November 11 with a special breakfast and program in their honor. Our students and staff served breakfast and performed songs proclaiming our freedom in this land we love. Thank you veterans!
