All NCLB did was start this unnecessary focus on "data points". Under NCLB, teachers began teaching a little and assessing a LOT. We had to adopt a "research-based assessment" that had to be given to every student in the class three times a year (a one-on-one assessment, by the way). Even the kids that you KNOW will score off the charts - you still have to take time that could be used to teach so that you can get their data points down.
Common Core is NCLB on steroids.
