The science and safeguards behind Testora IQ
A cognitive assessment is only as good as the data behind it. Here is how Testora IQ items are written, calibrated and scored — and how your results are protected.
- 0.91
- Internal consistency (Cronbach's alpha) across the 40-item battery
- 0.86
- Test–retest correlation at a 90-day interval
- 18,400
- Adults in the current normative reference sample
- 5
- Independently calibrated cognitive domains
How results are calculated
- 1
Item response scoring
Every answer is weighted by that item's calibrated difficulty and discrimination, so a hard item earns more than an easy one. Speed is used only as a tie-breaker within the timed sections.
- 2
Domain aggregation
Weighted scores are pooled into five domains — logical reasoning, pattern recognition, spatial reasoning, numerical ability and working memory — and expressed as percentiles against the reference sample.
- 3
Normed IQ conversion
Your total is converted to a standard score with a mean of 100 and a standard deviation of 15, then reported with a 90% confidence interval of roughly ±4 points.
- 4
Interpretation
Your report pairs the number with plain-language interpretation of strengths, weaker domains and evidence-based practice suggestions.
Testora IQ is a screening assessment for personal insight and coaching. It is not a clinical or diagnostic instrument, and it should not be used alone for hiring, educational placement or medical decisions.
