Welcome to Callidus!

We are an international high IQ society with more than 500 members from all over the world. Founded in 2014 by web developer and IQ test creator, Randy Myers, Callidus was created to bring gifted individuals from all over the world together under one roof.

We are a private social network for those whose IQ sits at or above the 98th percentile. That is an IQ of 130 sd.15, 132 sd.16, or 148 sd.24. To join you must first register at IQ-Test.ca and either take any of our admissions tests to qualify or submit evidence from other tests for review. All our in-house tests use a standard deviation of 15 meaning your minimum IQ score must be 130 to qualify for membership.

The cost of a lifetime membership is $25 US which includes an automated downloadable membership certificate with your name on it, your name listed in our members directory and lifetime access to our members only private social network.
