Education Week released a collection of articles focused on data use and the tools that facilitate this use. While little was said of OTCD design concepts relating to data systems and their reports, there were some related insights. For example, after working with educator focus groups to improve the helpfulness of their feedback reports, postsecondary enrollment growth in the state of Kentucky rose from 50.9% in 2004 to 61.4% percent in 2010 (Ash, 2012). Also, on the note of data use in general, a study of 59 districts in 7 states indicated students in districts where teachers utilized data-driven decision-making outperformed control-group districts' students by approximately 8 percentile points in math and 5 percentile points in reading (Zubrzycki, 2012).
