Extension and 4-H youth development programs are addressing a shortage of scientists, engineers, and other related professionals by promoting science, technology, engineering, and math (STEM). This case study illustrates how the Oklahoma 4-H Youth Development program trained youth-adult teams to design and implement STEM projects. The STEM Institute incorporated the 4-H Eight Essential Elements to structure programming. Using the Essential Elements framework helped ensure quality STEM programming, participant retention, and successful community projects lead by youth leaders. The most successful projects were youth driven and adult facilitated, used local partners, and took time to develop.
