Welcome Back, T.F. South Families!

Dear Parents and Guardians,

As we open the doors for a brand-new school year, I am thrilled to welcome you and your family back to T.F. South High School. This year’s theme—Built on Tradition, Driven by Progress—reflects our deep-rooted commitment to academic excellence, community, and continuous growth.

School begins Monday, August 18th, and we can’t wait to see your student walk through our doors, ready to learn, grow, and thrive.

We are proud to celebrate some extraordinary achievements that embody this theme:

  • 87% of last year’s 9th-grade students finished on track, the highest rate of achievement for a freshman class at T.F. South in the last eight years, demonstrating resilience and strong transitions into high school life
