The tests at High Range Tests are certified by the Callidus High IQ Society.

About Our Society

Callidus membership is open to very bright individuals that possess an intelligence quotient found in 1 out of every 50. Our society was founded in 2014. We have gathered members from all over the world since 2014. Our founder, Randy Myers, is the founder of many high IQ societies. It costs an extremely affordable $10 to join our society, with no recurring fees. All of our members, roughly 500 of them, communicate on our website forum and Facebook groups. Our members access their forum though their user dashboard, which has other features as well. New members are awarded a digital certificate and account information at no extra charge and are entitled to attend any future gatherings. Our members must abide by our society rules. We do not allow trolling(harassing other members). Our staff will warn the person, and if this problem continues, will ban the person. It is a society filled with intelligent individuals that enjoy engaging in intellectual conversation, but it is also a safe society. Do not hesitate to join us and enjoy the many benefits of being a Callidus member and meeting new people.
