    Frequently Asked Questions

    Is this an official IQ test?

    Our test follows official IQ testing standards and methodology. While 'official' clinical IQ tests must be administered by licensed psychologists, our assessment uses the same CHC cognitive model and provides comparable results for personal insight.

    How does this compare to WAIS or Stanford-Binet?

    We use similar question types and cognitive domains as official tests like WAIS-IV. Our test has been validated against clinical assessments with a correlation of 0.85+, making it one of the most accurate online alternatives.

    Will my results be recognized officially?

    Online IQ tests are not recognized for clinical, legal, or educational purposes. However, our test provides an accurate estimate of your cognitive abilities for personal development and self-understanding.
