IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults.

According to Weiten, "IQ tests are valid measures of the kind of intelligence necessary to do well in academic work. But if the purpose is to assess intelligence in a broader sense, the validity of IQ tests is questionable." [92] Some scientists have disputed the value of IQ as a measure of intelligence altogether.
They conclude that "in contrast to most studies on the association between childhood IQ and later health," their findings suggest "a high childhood IQ may prompt the adoption of behaviors that are ...
Coding (primary, FSIQ) – children under 8 mark rows of shapes with different lines according to a code, children over 8 transcribe a digit-symbol code using a key. The task is time-limited. Symbol Search (primary) – children are given rows of symbols and target symbols, and asked to mark whether or not the target symbols appear in each row.
