On receipt of the application, your sponsors will be notified and asked to submit a written recommendation for your membership. When these sponsor letters have been returned, the completed application will be reviewed by the Membership Committee. The Committee reports on the applications at the next meeting where applications are presented for approval by the Board of Directors and subsequently the general Membership.

All members, except Student and Members Emeritus, pay annual dues of US $60/year. As a Member of any classification, you will recieve C.A.T. mailings, and have access to online Proceedings of the tri-annual meetings.  At the present time, dues are assessed only after the Board and general Membership have approved your application. You will also receive a yearly Membership Roster listing all members and their addresses.

Also available to members is the option of participating in a Proficiency Program with samples prepared by participating members.
