Located downtown in two freshly-renovated buildings on the Fox Tech campus, the school will work hand-in-hand with industry partners to prepare students for careers in technology and business, fields where the demand is high for talented workers.

Some features of the unique program include hands-on projects and real world problems to solve, as well as job shadowing, mentorships, internships and job opportunities upon graduation.

CAST Tech will use computer-based learning to allow students to progress more quickly in areas where they have mastered concepts, allowing them to dive more deeply into projects and areas of great interest. College coursework is embedded in the program, and students can graduate with an associate's degree, industry certifications and portfolios that feature long-term projects and other examples of their work.

Industry partners for CAST Tech include: H-E-B, Tech Bloc, Whataburger, CyberFortress, Geekdom, AT&T, USAA, Frost Bank, DOCUmation, and City of San Antonio, Bexar County.
