From the rule book.... I would email Marc Lipp at the NRA TPC page and ask.
2.1.10 Invitational: At the discretion of the Match Director persons who do not meet TPC eligibility requirements may be allowed to participate. These may include volunteer match officials, match sponsors, and firearm industry representatives. Invitational competitors are not eligible for awards, plaques or prizes. Recorded scores are normally maintained and published separately from regular competitors.
