Join Jacksonville's premier society. To join, you must pass our qualifying test. Tests are scheduled periodically. For more information, please email us at mensajaxpres@yahoo.com or call (904) 693-4451.

Another way to join is by providing prior evidence. This would consist of proof of a qualifying score on one of many accepted tests that you took in the past. Often potential members do not realize that they already qualify for membership. To see which tests are accepted, please click here .

Membership dues are $52 per year. If you are already a Mensan, but live outside of the Jacksonville area, you may join us by "preferencing" into our group. We welcome American Mensans living anywhere in the world. Just call the national headquarters (1-800-66-MENSA) and ask to "preference" into Group 10-322.
