4‑H (National 4‑H and state 4‑H Youth Development programs)

4‑H (National 4‑H and state Cooperative Extension 4‑H programs) is a nationwide youth development organization that runs major conferences (e.g., the National 4‑H Conference) and operates or partners in after‑school, school enrichment, and out‑of‑school‑time (OST) programming (often called 4‑H Afterschool or 4‑H Youth Development at the state level). While 4‑H is not solely an "after‑school conference organizer," it clearly organizes conferences and convenings and runs after‑school/enrichment programs, so it is a relevant match for conference-organizer needs in the afterschool/enrichment/OST space.
