Key takeaways

  • The foundation focuses its giving on Uvalde, Texas and the greater South Texas geographic area, funding children's interests, agriculture, Southwestern history, culture, art and literature, and health care, plus K-12 education and literacy through its EduKate programme, which prioritises rural, low-income or at-risk communities and evidence-based work.
  • A realistic request sits within its typical $10,000–$1,000,000 range, with half of its recent grants at $100,000 or less (median $100,000, largest $15,000,000).
  • Approach via a Letter of Inquiry submitted on a rolling basis; a strong LOI may be invited forward for a fuller proposal, though an invitation does not guarantee a grant, and previously funded organisations must submit an accounting and impact report before further funding is considered.
  • Only 6% of recent grant dollars went to organisations it had also funded before, suggesting room for new applicants, but the foundation will not generally fund 100% of a programme and does not cover administrative costs, debt reduction, fund-raising efforts, table purchases, or grant solicitations from individuals.
