The Vergers Guild of the Episcopal Church offers a comprehensive training course for vergers: "A Course of Training for a Verger." The course enriches the development of a verger with information about the roles, responsibilities, interpersonal relationships, and practical aspects of being a verger.
To purchase the training course you must be a member of the VGEC. If you purchase the course and are not a member, you will be granted a 6-month free trial membership.
The cost of the course is $65. This covers course materials and the administration of the course. The course is delivered as a password protected PDF attachment to an email. Actual enrollment in the training course is processed with the enrollment form on page 10 of the course and requires clergy endorsement.
