ANSWER: According to the WSPTA’s “PTA and the Law” handbook, “Auctions do not constitute a gambling activity. Under state law it is, nevertheless, generally unlawful for any person to act as an auctioneer without a license. However, there is an exception to this general rule for auctions conducted by or on behalf of a charitable organization if the person conducting the auction receives no compensation.”
However, if a PTA is planning a raffle as well during the event, this portion would be considered a gambling activity and the PTA would need to obtain a raffle license. There are specific guidelines established by the Washington State Gambling Commission on running raffles. Be sure to become knowledgeable on the rules and guidelines by going to their website.
