Colloquy is an internet-based organization of individuals who have qualified for membership by virtue of performance on IQ tests and other accepted standardized tests including the ACT, GRE, PSAT and SAT. In online literature the group claims "Colloquy is, to the best of our knowledge, the first high-IQ society based entirely on the Internet."
Through its membership criteria, Colloquy accepts individuals with an intelligence quotient measured in the top 99.5 percentile. Contrast this with the more popular Mensa International, accepting members in the top 98th percentile, and more "selective" organizations such as the Triple Nine Society, the Prometheus Society and the Mega Society that accept members in the 99.9 percentile and higher.
As of January 1, 2006, Colloquy maintains an online discussion through Yahoo Groups.
