Apostello provides access to seminary level training for Christian leaders and ministers via the Capstone Curriculum. The Capstone Curriculum is a sixteen module training program designed to impart the most essential knowledge and skill learning necessary for effective urban ministry and church leadership. Modules are organized into four overarching themes: Biblical Studies (God), Theology and Ethics (Kingdom), Christian Ministry (Church) and Urban Mission (World).

Courses are taught online with a cohort discussion group meeting in person weekly (a virtual option is available for distance learners).
