Rigorous

College-Prep Curriculum

The robust core subject offerings and specials offered at STA prepare students for the academic challenges of college and beyond. The Center for Academic Achievement and School Counseling Department are great resources to foster academic skills while gaining knowledge about college admission processes. Through our program, graduates develop the skills to be critical thinkers, independent learners, and effective communicators.

In addition to enrichment offerings year-round, STA students have a seasonal term to explore and dive deep into courses that spark their interest. Financial Management, Scuba Diving, Japanese Culture, and Comparative Vertebrate Anatomy are just some of the many unique courses that ignite every student’s passions and gifts.

A high school that enriches and inspires.

“Our daughter was ‘welcomed home’ as if she always belonged at the school. She integrated with her classmates seamlessly, formed immediate bonds with her teachers, and joined many after-school activities. She jumps at the opportunity to volunteer for community service events and understands that being a part of STA means having a responsibility to the community.”
