The Summer Internship Program exists to help emerging leaders explore their calling to vocational ministry by developing character, capacity, and foundational leadership competency. Interns receive intentional training, mentoring, and hands-on ministry experience while serving within a defined ministry track. The program also prepares future leaders for the ongoing growth and expansion of The Tree and the broader Church. The Summer Internship is a 10-week immersive experience designed to introduce interns to ministry leadership and the rhythms of staff culture.

The Tier 2 Internship is the intermediate phase of the Leadership Development Program. It is designed for individuals who have demonstrated leadership potential through prior ministry experience and are seeking deeper confirmation of calling, increased responsibility, and practical leadership growth. This experience is gained through ministry tracks such as worship, production, creative, discipleship/care, hospitality, groups, young adults, children's ministry, and youth ministry.

The Staff Residency is the capstone phase of the Leadership Development Program. It prepares emerging leaders for potential full-time ministry through advanced leadership responsibility, pastoral maturity, and the ability to lead and multiply other leaders. Residents model staff culture, carry systems-level leadership, and help shape the development of future leaders. Residents continue serving within a ministry track while expanding leadership scope and influence.
