Created in partnership with SWISD, CAST Schools and Palo Alto College, CAST STEM emphasizes preparing students for high-demand jobs in engineering and advanced manufacturing. Southwest ISD utilizes social media to keep our students, staff, and community informed by sharing important updates, positive news, school closures, and upcoming events.

• Advertise or promote products, services, or events unrelated to Southwest ISD.
• Solicit business, membership, or financial contributions for organizations unaffiliated with Southwest ISD.

• Use multiple identities or another person’s name to comment.
