IQ testing by age band
The right answer depends on age. Children, teens, adults, and seniors each get something different from the test, and each runs into different pitfalls. Choose the one that fits.
IQ test for kids
What the Stanford-Binet Online is built to capture in a child.
- The factor profile — where a child is strong, where they need support
- What the test measures at 5–11, and when ages 10+ is the sweet spot
- How the five-factor model informs teaching style
IQ test for teens
Adolescents are the easiest population to test well.
- Why teen scores are unusually reliable
- College admissions, Mensa, and academic decisions
- What the five-factor profile reveals about a teen’s learning style
IQ test for adults
Why most adults take the test for self-understanding.
- Self-understanding vs. credentials — what the score is for
- What stays stable and what shifts after 25
- What 35–45 minutes of the Stanford-Binet Online actually tells you
IQ test for seniors
Cognitive assessment after 60 — what stays, what goes.
- What stays sharp after 60 (knowledge, vocabulary)
- What naturally slows (Innate Intelligence, processing speed)
- When a score should send you to a doctor instead
Not sure which fits? 18 and over: pick adults. A 12-year-old with academic concerns: kids. A 17-year-old applying to college: teens. When in doubt, the adult guide is broadest.
