Editorial review: strengths, limitations and current access conditions.
OpenPsychometrics provides an educational Full Scale IQ Test with six sections covering memory, reasoning and verbal abilities. It presents an overall estimate and component scores, with references and clear warnings about online-test limitations.
This is one of the more useful new additions for exploring several cognitive abilities without a paid-result funnel. Its transparency deserves credit, while the older interface, lack of verified formal certification and online sampling limitations keep the rating below a professional assessment. Task counts differ by section, so the directory displays a variable count rather than an invented number.
The rating reflects suitability for this directory, including transparency, accessibility and useful feedback. It is an editorial comparison score, not the percentage accuracy of an IQ result. The service should be considered alongside its stated limitations and current payment terms.
This review uses public product information and provisional editorial scores, updated on 12 October 2026. Unknown criteria receive a conservative estimate and are identified in the assessment table. We did not purchase reports, audit security or independently validate the scoring algorithm for this update.
