Certified tests from IQexams.net are currently accepted as admission criteria by the following High-IQ Societies:

Note that you must order a Certified result to be listed in any of the societies below. The automatic email score report that you will get is NOT a Certificate.


(We have been accepted by other IQ Societies as well, most likely many more will accept, just check.)

Order certificate
1. Please send a separate E-mail to [email protected] and let us first check if you have a valid test attempt.
2. We kindly ask you to also attach a certificate from at least one other IQ-test with a somewhat similar IQ score, or if you provide us with a link to another scoreboard.
3. If you are approved, we can proceed with the certificate. The price is set after membership level, please see: Membership & Prices
4. PLEASE NOTE! You must have done the test in a proper way to be approved, the test engine easily detects anomalites and indicate this to the IQexams admin. It is not fun for us to say no to certification, but sometimes we have to.

Note that unlike most untimed high range tests, we base our norms on much higher numbers of test submissions, normally we set the first norm at around N=70. Very few other test authors use tools when working with psychometrics and seems to base their norming on score pairs means only. IQexams uses PSPP or SPSS to carefully calculate the norms about 3-10 times with deep quality inspections of the norms before we are satisfied with the 1st official norm. Mean and rarity at several levels and correlations to proctored or psychometrican made tests are carefully checked and optimized to be as close to 1 as possible. We remove tests that can not measure the real g-factor IQ good enough. An items analysis is always made in SPSS to check so that there are no weak items that can downgrade the quality and If the total reliability is not high enough, we normally withdraw the test. We have normed about 100 IQ tests do far and has a extensive knowledge about this. Our tests are executed up to 2000 times per month.

Most "serious" IQ societies accept HRTs with no psychometric data at all and with only with simple score pair matchings made at N=30. If they refuse to accept certificates from IQexams (any author) Please send the text above as information how the norm is set by us.
