We have spent 10s of trillions on War on Poverty and Education in the last 50 years and they are worse than ever.
33 points? Ouch.
It would be nice if the educrats actually posted the sample sizes so we can uncover whether the decline is statistically significant, but nah, that would involve actual research.
With a sample of 1 million students, you’d have an error of plus minus a point. If you multiplied the number of students by 10, you’d have plus minus .6 points.
To explain a decline of 33 points, you’d need sample differences of 10 million to 500 people taking the test.
The decline is real, no matter what the educrats would have you believe.
