Mensa test can be administered by third-party services or local schools and colleges. Just make sure that before you take the test at one of these places, that you do your due diligence and find out if they are Mensa certified. Unless you are taking the test for your own personal knowledge, it would be a shame to spend all that time and effort in taking an in depth intelligence test just to find out that it was not recognized due to lack of certification by your testing facility. Contact American Mensa Ltd. at American Mensa Home they will be able to lead you to the proper test site in your area. If you are not in the United States or would like to find a site in another country you can contact Mensa International for your country's specific information.
