Ask a Psychiatrist and Get Answers to Mental Health Questions ASAP
Good evening, and welcome to JA.
I have been conducting cognitive evaluations for over 20 years now (even before being licensed independently 15 years ago). If you have 2 or more results that suggest a range of 120 (and you quote the statistics on correlations with the WAIS and Ravens) then in all likelihood, you have an IQ at least one standard deviation (+15) above the norm (100). There is a strong possibility, given that you suggest your performance was in the hi-120s, that you might actually be above two standard deviations (+30) above the norm (100).
I will be frank with you, however, if you are trying to have your IQ validated for some purpose, you will be required to have it assessed using legitimate sources. (In other words, you'll probably have to take the test they recommend/require and/or meet with a Clinical Psychologist for a private evaluation.)
Nevertheless, your performance on these others assessments would suggest that we could predict, with 95% accuracy, that you would perform in the hi-120s (and perhaps lo-130s) on such an assessment.
I hope this is helpfull.
