School Reviews

5 10/10/2025

I've been volunteering at Thornton Elementary for the past four years, and I highly recommend this school. The teachers are excellent. The school has music, art and PE for exploratories. My only complaint is the students do not spend enough time on computers. It is essential for elementary students to become computer literate. I am a retired Media Specialist from Aurora Colorado.
