Mensa IQ Test Score Chart — Percentiles and Scale Conversions
How to read Mensa qualifying scores across WAIS, Stanford-Binet, and Cattell scales using percentile bands.
A Mensa IQ test score chart maps raw performance to percentile ranks — the statistic Mensa chapters actually use for the top 2% cutoff.
Reading percentiles vs IQ points
Percentiles are scale-independent: 98th percentile is the society threshold whether σ is 15, 16, or 24. IQ point equivalents differ by instrument.
WAIS-IV band (σ = 15)
Scores from 130–131 typically meet Mensa norms on Wechsler scales used in prior-evidence submissions.
Cattell Culture Fair (σ = 24)
A 148 on Cattell scales reflects the same rarity as 130 on Wechsler — never compare raw numbers across scales without conversion.
