I agree. Some of this is about the number of people taking it. But the average grade rising is supposedly a sign of increasing results. One more point. My friend at UCLA who studies IQ has said that normal is always a median of 100. However the curve is moving left meaning the average is going down.
SAT Comprehensive scores peaked and have never recovered since 1972. And yet grades have gone up!!
This data causes cognitive dissonance. Pick one. I pick that generally those entering in college college are not as smart as the cohorts in the 70′s
