Each president has his education law that changes the previous administration's law, and the Obama administration's iteration allows a more local approach to data collection.
"K-12 education systems have been awash in data for years. Now, thanks to changes in federal and state policy, and coupled with millions in investment from funders over the years, educators are making better use of that data.

Other data systems gauge student progress toward reading on grade level by third grade, a metric that studies have identified as a key predictor of future academic success."--L.S.
