Please note; European versions of tests that Intertel accepts can have different scores/percentiles than the American versions. The scores listed on our website only apply to the American versions. The percentile is the important criterion. Intertel will accept Mensa percentile reports as qualifying evidence.
Prospective members can send a copy of their Mensa test results report that specifies a 99 percentile (regardless of the numerical score) as their qualifying evidence for membership in Intertel.

More information here about joining American Mensa®, joining Mensa in the UK and joining other national Mensas.

We understand current members of American Mensa® who tested between April 1, 2001, and Dec. 31, 2010 can request their raw test scores from American Mensa's® Admissions Manager at no charge. We further understand lapsed members and past Offers of Membership will pay a $15 fee for their score report. A chart interpreting the raw scores is available at Mensans who incur a fee to obtain their test scores will receive a discount on their first year's dues if they use those scores to join Intertel.

RENEWAL PAYMENT OPTIONS are now available through Paypal.

Potential new members please use our standard Intertel Application Form (right click image/save/print/mail)

Intertel Application Form

With your application, you should enclose evidence of a qualifying score on a standard supervised test of intelligence. This evidence cannot be returned to you, but legible photocopies are acceptable. If the scores are maintained by a university or other service that cannot provide the results directly to you, request that they forward the evidence to this Committee, and attach a copy of your request to your application.

Please do not ask us to obtain the evidence for you. It is your responsibility to provide it to the committee.

Any test score you submit will be kept completely confidential.

Intertel does not provide testing services. If you have no evidence, and believe that you might qualify for membership, a supervised test may be given by a local university, psychological clinic, or private psychologist. Before taking such a test, please be sure it is one of those accepted by Intertel (see below)

You will be notified of the results of the Acceptance Committee's evaluation of your application. If you are found to be eligible for membership, you will be invited to join by sending in the dues payable for the current year. If you have any questions, write to the Acceptance Committee at the address given.

NOTE: No self-administered tests will be accepted.
