The your regional membership is all you need. Since the WAC isn't a formal organization itself, but rather a support tool of the four regions, so there is no need for an additional membership.
We do ask that you join at least one of the following regional groups.
- SWAP - SouthWestern Association of Planetariums
- GPPA - Great Plains Planetarium Association
- RMPA - Rocky Mountain Planetarium Association
- PPA - Pacific Planetarium Association
Each group has their own membership, rules, and leadership. These are your organizations, and they rely on your generous support of time, talent, and treasure.
Additionally, we encourage involvement and membership in IPS, the International Planetarium Society.
