The Corporation for National and Community Service (CNCS) sponsors numerous training events for its AmeriCorps VISTA members, including a variety of In-Service Training (IST) events, which will typically focus on a particular theme related to community service and volunteer development. Occasionally, the Corporation State Office may contact you about an IST event that your members may be required to attend.
