Columbia River Mensa is a local chapter of American Mensa whose boundaries cover a large portion of the state of Washington, from Oregon in the south to the Canadian border in the north. Our ranks are growing ever stronger, as more and more interesting people test for and accept membership into our group. Our local group was the proud recipient of the prestigious Prodigious Owl award in 2003, awarded to the group with the most growth for the year. If you are interested in joining, please visit our Testing Page for information on upcoming tests in your area.

American Mensa has over 50,000 members who come from all walks of life and all levels of society. However, they share one trait - high intelligence. To qualify for Mensa, one must score in the top 2% of the general population on a standardized intelligence test. Five million Americans are eligible for Mensa membership. As an organization, American Mensa provides intelligent individuals an opportunity to meet other smart people at the local, regional, and national levels.

Mensans interact at entertaining events and exchange ideas through a variety of publications. Mensa members also work to help others in their communities by providing scholarships and volunteering for community-oriented activities.

Columbia River Mensa holds monthly dinner meetings on the fourth Saturday of the month, with other events, such as games nights, social get-togethers, plays and festivals, etc., scheduled throughout the year. Encompassing such a large geographical area, we try to cover a lot of ground. If you would like to suggest or host an event anywhere in our area, please contact the local secretary.

American Mensa has 136 local chapters throughout the 50 states, District of Columbia, Puerto Rico and the Virgin Islands. These chapters range in size from 15 members to more than 2,200 members. American Mensa's national office is in Arlington, Texas.
