Core Values






Core Beliefs

 At San Antonio Prep, we will set the standard for what is possible for our students, and our vision is guided by two unwavering and bold beliefs: 

(1) We believe that all students, no matter economic status, race, family educational levels, zip codes, or home languages can achieve at high levels.

(2) We believe that all students deserve a high-quality, college preparatory education, with a focus on literacy and mathematics in middle school, college preparatory work in high school, and the development of 21st century digital literacy skills in all grades.

About the Lead Founder

Stephanie Hall Powell


Stephanie is passionate about equity in education and providing quality school options to families. She started teaching in the United States Air Force as a military training instructor. Stephanie spent 10 years in the military before deciding to homeschool her three children. She became a teacher when, while homeschooling her own children, she realized how important a good education with purposeful leadership was for children. She joined IDEA Public Schools in 2014, serving as a middle school teacher and high school teacher before becoming the school’s Assistant Principal of Instruction in 2017. In that role she managed a team of teachers, coaching and facilitating their professional development to drive assessments results. In her role as proposed school founder and leader, Stephanie is persistent in serving as an agent of change, “Children deserve a quality education and it is my responsibility to provide equity and excellence.” Stephanie holds a Bachelor of Science in Psychology from the University of Maryland University College and a Master of Education Administration from Concordia University Texas.
