Requirements

Admission to STHIQ Society requires evidence of valid IQ scores obtained in at least 2 tests (chosen among the ones selected by our admission-staff): 1 “spatial test” and 1 “logical or numerical test”. Tests containing mixed items are valid for any category (spatial or logical-numerical).
No verbal test is accepted in STHIQ.

Note: our minimum requirements (top 0.1% for full membership, top 0.5% for prospective membership) must be reached in each test, individually (so the mean of the two scores is not taken into account).


Memberships and requirements:
  • full membership:   IQ belonging to 99.9th percentile  (146.4 sd15)
  • prospective membership:   IQ belonging to 99.5th percentile (138.6 sd15)
  • honorary membership:   presidents of some high IQ societies may join STHIQ as “Honorary
    Members”. Only well known and appreciated high IQ societies will be taken into account
    for this kind of membership.
