Partnering Together To Reinvent How Students Learn

A committee of industry leaders, school superintendents and workforce development experts proposed the CAST model after studying innovative high school models across Texas and the nation.

In June of 2016, Charles Butt and H-E-B announced they would provide startup funds to develop the CAST Network and its first school, CAST Tech, in partnership with San Antonio ISD and Tech Bloc, a technology economy advocacy movement, as well as a core group of local employers. San Antonio College and UTSA rounded out the partners.

The CAST Schools Network is now 5 high schools and 1 pre-k through 12th Academy in 3 different independent school districts. CAST Teach, the network’s 6th school, will open in August 2022 in partnership with Northside ISD.

The Importance of Partnering with Public Schools


CAST Schools are built in partnership with public schools. Today, CAST Schools are a network of 5 schools in three (3) different school districts, East Central ISD, Southwest ISD, and San Antonio ISD. The network’s sixth school, CAST Teach will open in August of 2022 in Northside ISD. Former San Antonio ISD Superintendent Pedro Martinez was the very first to take a leap of faith in CAST Schools. During our first annual CAST Champions event, Superintendent Martinez shared why he was the first superintendent to believe in CAST Schools.

Working with Industry to Create Authentic Learning Experiences

Working with industry provides students at CAST with the opportunity to gain authentic learning experiences, connect to jobs, and have hands-on learning in fields that are fast-changing.

Leveraging the Schools’ Advisory to Provide Experiences Beyond the Classroom


Dr. Melissa Alcala, CAST Tech Principal, shares how the school’s industry advisory board, and the over 100 partners at each CAST School, help extend experiences for students beyond the four walls of the classroom.

Helping Transform San Antonio

Mr. Weston shares how CAST is helping transform San Antonio as a place to work, live and play.

Investing in the Future


As Chief Information Officer for H-E-B, Gavin Gallagher never missed a meeting when CAST Tech was being built. Mr. Gallagher shares why he dedicated so much time to the creation of this flagship high school and why H-E-B is such a committed supporter of CAST Schools.
