No.

- predictive power grades peaks in early school years, weakens with time. (6-12, 0.6+

Ex: Less than 0.5+ sat correlation with better college grades first year, ??higher when adjusting for high scorers electing tougher classes??ASK, but by GRE, 0.4+

-intelligence scores correlate more closely with scores on later achievement tests (RELIABLE? ASK) - 0.81+

Ex;comparison of 70k english children's intelllgience scores at 11 w/ academic achievement or national exam scores at 16

Ex: football linemen- sucess correaltion between larger the range- 300lb tends to beat 200lb but when within professional range 280-vs-320 narrow range, negligiable correlation

Ex 2: elite uni takes only those with high aptitude scores, gives the restircite range of high grades, scores cannot predict much ASK EX

(true even if test has predicitive validity with more diverse sample of students)- grade inflation - now predict college scores no better than SAT?
