— IQ score interpretation

What does an IQ of 74 mean?

IQ Score

Band

Borderline

Rarity

bottom 4.2%

An IQ of 74 places you in the Borderline band — the bottom 4.2% of the adult population. On a standard IQ distribution (mean 100, standard deviation 15), this corresponds to the 4.2th percentile.

What this score actually means

An IQ of 74 is in the Borderline range — below the typical normal cutoff of 70 but above the intellectual disability threshold. People in this range often need additional support in abstract academic settings but can lead independent adult lives, hold steady employment, and form meaningful relationships.

How rare is IQ 74?

An IQ of 74 or lower occurs in roughly the bottom 4.2% of the population. In a typical room of 100 adults, you'd expect about 4 to score 74 or below.

Professions and IQ 74

Professions where the typical practitioner scores near IQ 74 include construction (~96), truck driving (~92), hospitality work, and trades that reward physical and procedural skill over abstract reasoning.

The limits of a single IQ score

A composite IQ score is useful but it conceals the underlying cognitive profile. Two people both scoring 74 can have very different strengths — one may excel at verbal reasoning and lag at spatial; another may be the reverse. Core Brain decomposes your score across six cognitive axes (pattern, numeric, verbal, spatial, logic, matrix), giving a more useful picture than the single number.

The score is also not destiny. Educational interventions, learning disabilities, sleep, motivation, and time of day all shift measured IQ. Standard error on a single test is typically ±3-5 points. Two tests taken months apart by the same person can differ by 5-10 points without anything meaningful having changed.

Frequently asked

Is IQ 74 good or bad?

An IQ of 74 places you in the Borderline range — 4th percentile. It is below the population average. Many successful people score at this level; outcomes depend much more on character and effort than IQ.

Can IQ 74 qualify for Mensa?

Mensa requires an IQ of 130 or higher on Wechsler-scaled tests (98th percentile). IQ 74 does not meet the Mensa threshold by 56 points.

How accurate is an IQ of 74 from an online test?

Online IQ tests are calibrated against normed distributions and approximate clinical tests reasonably well for healthy adults under timed conditions. The standard error is typically ±5 points. For high-stakes decisions, only a professional WAIS-IV or Stanford-Binet assessment is definitive.
