The following is a guide to assist the Faculty Adviser and Registrar in qualifying students for membership while complying with National and Chapter Bylaws:
The culling process for inviting students can be fairly complex for a given College or University.
If a chapter inducts undergraduate, graduate, and doctorate students, the query should consist of separate steps for each: one for Juniors, one for Seniors, one for Graduate students and one for Doctorate students..
While this is comprehensive, it will be thorough.
Your invitation letter can eliminate existing members with graceful wording. Or, the requested mailing labels could be manually culled to remove existing members. Ideally, the member's school record has been tagged to identify DMD membership and the tag can be exempted during the selection.
There can be exceptions to the residency requirement - where the transfer credits were earned at a school having a DMD chapter or which has 4-year ACBSP accreditation. This would likely have to be handled on a case-by-case basis.
