Intertel is a high-IQ society founded in 1966 that is open to those who have scored at or above the 99th percentile, or the top one percent, on a standardized test of intelligence. It has been identified as one of the notable high-IQ societies established since the late 1960s with admissions requirements that are stricter and more exclusive than Mensa.

Intertel is open to those who have scored at or above the 99th percentile, or the top one percent, on a standardized test of intelligence. It has been identified as one of the notable high-IQ societies established since the late 1960s with admissions requirements that are stricter and more exclusive than Mensa.

Intertel was founded in 1966 by Ralph Haines, following the example of Mensa founders Roland Berrill and Lancelot Ware, who wanted to create an association adapted to the gifted needs without any specific restriction of admission (with the exception of a minimum IQ). Intertel thus became the second oldest organization of this kind, Mensa being the first.

Aligned with one of the goals stated in its constitution, Intertel's members participate in research on high intelligence.

In 1978, Intertel established the "Hollingworth Award" in memory of psychologist Leta Stetter Hollingworth, who specialized in research on gifted children. This award was annually presented until at least 1993, first sponsored by Intertel and then the Intertel Foundation.
