EXCEPTIONAL INTELLECT • ARISTEIA

Apply for Membership

Aristeia High IQ Society recognizes individuals who demonstrate exceptional intellectual ability, with membership beginning at an IQ of 140 on the SD15 scale.

Admission to Aristeia

Aristeia High IQ Society is a community for people whose intellectual ability places them among the higher ranges of the population.

Membership is available to individuals who demonstrate an IQ of at least 140 SD15. Applicants may establish qualification by submitting results from an accepted intelligence assessment for review.

The admissions process is straightforward. Submit your qualifying result and supporting documentation for review. Once your qualification has been approved, you can complete your membership.

Aristeia Qualification

The minimum admission level for Aristeia is:

IQ 140+
SD15

Submitted results must correspond to an IQ of 140 or higher on the SD15 scale.

Because assessments use different scoring systems and normative frameworks, submitted results are reviewed individually.

Submit Existing IQ Results

If you already have a qualifying IQ result, you may submit it to Aristeia for consideration.

Submitted results should clearly identify the assessment taken, the resulting IQ score, the applicable scoring scale, and the testing conditions.

  • The result must correspond to an IQ of 140 or higher on the SD15 scale.
  • The assessment must provide sufficient evidence of intellectual ability.
  • The submitted result must be attributable to the applicant.
  • Supporting documentation should be provided whenever available.
  • Aristeia may request additional information when necessary.

Accepted Proctored Assessments

Aristeia recognizes qualifying results from established intelligence assessments administered under appropriate professional or proctored conditions.

The following assessment families may be submitted for consideration.

Results Review

Meeting or exceeding a numerical score does not automatically guarantee admission. Submitted results are reviewed to determine whether the assessment and result provide sufficient evidence for Aristeia qualification.

Aristeia reserves the right to request clarification or additional documentation before approving an application.

Applicants should provide their name, the name of the assessment, the reported score, the applicable scoring scale, and documentation showing the result.
