What it means in practice
Mensa admits the top 2% — about IQ 130 on a test with a standard deviation of 15. A score of 145 clears that line, so it would qualify on most tests Mensa accepts.

No test measures IQ exactly. A typical standard error is about 5 points, so a result of 145 really means "somewhere between 140 and 150" — and a second test on another day can land anywhere in that range.
For a child the number compares them with others of the same age, not with adults. IQ scores are age-normed, so a 10-year-old and a 40-year-old with the same score are each equally far ahead of their own age group.
