> [GPAs a]re as predictive as or more predictive of future educational performance (usually first-year college GPA) than test scores, despite grade inflation (which isn't as extreme as some would have you think).

But in the context of this finding, the returns to grade inflation are limited by the fact that, when you report your GPA, you also report a standardized test score. This theoretically nullifies any potential benefit to grade inflation. (In practice, there's still a benefit.)

When there is no outside check on the reliability of GPAs, might they adjust by inflating a lot more than they already have?
