Interesting to contrast public schools now with public schools of the early 20'th century. I remember reading the book 'Truman' by David McCullough. Truman completed High School and could both read and write ancient Greek.
Fully seventy percent of all freshmen entering community colleges have to take remedial math and/or English classes before they can even think about taking college level courses that will count toward their AA degrees. That figure was per one of my community college professors when I went back to school to finish my prerequisite work for getting into engineering school.
And that was over ten years ago - I can't imagine that percentage is any lower today, and it's probably higher. So now we have colleges teaching kids what they should have learned in K-12, and according to this article, it's more and more up to employers to teach them what they should have learned in college!
But at least we can take pride in the fact that no one can put a condom on a cucumber better than our high school and college "graduates."
