An intro fellowship is a program in which a dedicated group meets several times to learn about effective altruism. Typically, intro fellowships consist of weekly readings and discussion groups for a period of 6-10 weeks, in groups of 3-10 people. Fellowships are a high-intensity and high-fidelity way of learning about EA, and many local EA groups run an intro fellowship as an early/middle part of their funnel. 

Intro fellowships are sometimes called introductory programs, seminar programs, scholar’s programs, and more.

EA Virtual Programs runs regular intro fellowships; anyone can apply to participate.
