Guide to Enrolling in CAST Schools for 2020–2021

CAST Schools is a nonprofit organization that partners with school districts to develop and support public high schools that get students ready for in-demand careers in San Antonio. The CAST Schools campuses are accepting applications for enrollment for the 2020–2021 school year. We have put together a guide to help you learn more about CAST Schools including CAST Tech High School, CAST STEM High School, and CAST Med High School, to help you enroll your child for the next school year.

About CAST Schools

Since its founding in San Antonio in 2017, CAST Schools has focused on partnering with businesses and school districts to create campuses that offer state of the art, relevant education that gets students ready to launch successful careers. 

CAST stands for Centers for Applied Science and Technology. The common elements of every CAST school include project-based learning and work-based learning; also, many of the programs have a STEM focus. At CAST Schools, students learn about careers and have access to mentors who work in those fields. Partnerships with universities and relevant local businesses create access to college credit courses and certifications, as well as internships that offer real world experiences.

Each CAST campus has a different focus and set of partners. 

  • CAST Tech opened in 2017 and offers pathways in business, technology, and user experience (UX). Students prepare for careers in coding, cyber security, gaming, entrepreneurship, business, and more.
  • CAST STEM opened in 2018 and focuses on careers in engineering, advanced manufacturing, energy and power, and global logistics. 
  • CAST Med opened in 2019 and offers pathways in biomedical research, medical professions, and public health. CAST Med is a dual language school.
  • CAST Lead will open in 2020 focusing on retail leadership, hospitality and tourism leadership, and e-commerce leadership.

The process for families to enroll their children at CAST Schools is slightly different for each district partner.

Facts About CAST Schools

To learn more about the CAST Schools model, we toured CAST Tech with Mentor Coordinator Amir Samandi. The mentoring component brings career role models into students’ lives. Also, by staying in close contact with people who work in technology, the curriculum stays relevant and students are better prepared to enter the workforce at a high level.

CAST Tech students get to work on projects for real clients. It’s low-cost labor for the businesses—just the opportunity cost of the time spent supervising the students—and helps the students build a portfolio. The students get to “job shadow”—like going on a field trip, but to visit a business. CAST teachers also do externships to learn from the businesses and bring that knowledge back to the classrooms. 

Meeting with mentors helps students learn soft skills like how to welcome a guest, using email (rather than a messenger app) to schedule a meeting, and how to listen and ask thoughtful questions during a group session. 

The architecture at CAST Tech is more professional than academic. There are still classrooms, but there are also lots of flexible meeting spaces for small groups. A large foyer is filled with wide stairs that can turn into an impromptu auditorium. 

On the bottom floor of CAST Tech, the teachers who specialize in cutting edge technology have classrooms and labs to fit the students’ needs. Students on the technology pathway work in a classroom with a raised floor, like you would see in a commercial data center. They work on racks of servers and study for certifications like Red Hat Linux. Students on the user experience (UX) pathway work in a classroom that looks like a design studio with artwork and prototypes on the walls. On desktop computers, they work on projects involving game design and web design.

CAST Schools offer free transportation to students through their school district partners.

A branch of BiblioTech, Bexar County’s all-digital library, will open near CAST Tech in 2021.

The CAST Schools campuses have so many partnerships with businesses and universities that it’s a challenge to summarize, but one key partnership is TechBloc and CAST Tech. Also, H-E-B and the Charles Butt Foundation have been consistent supporters of CAST Schools.

Advanced Learning Academy (ALA) in San Antonio ISD is also part of the partnership with CAST Schools. Learn more about ALA in our enrollment guide to San Antonio ISD choice schools.
