> it's hard for me to see how you can raise graduation rates without lowering the bar.
That's easy, we live in a world where each generation is smarter than the previous. For IQ tests measuring abstract thinking todays teenagers score an average of 3 points higher than teenagers did 10 years ago.
This is due to better schooling, better edutainment of kids, and many other things such as increased focus on not leaving behind kids with learning disabilities.
The trend is starting to ease of in the developed world. But only in the last 10 years or so...
Whether the bar have been lowered is hard to disprove. But we know for fact that newer generations are far more book-smart than older ones where in their time.
Note. Some forms of pure generalized intelligence don't have the same trends. But analytical and abstract thinking, also commonly known as book-smart or good in school is trending upwords over the generations.
YES: kids today are actually smarter :)
