Analysis 1 Results and Interpretation: What do the two tables indicate about whether NCLB increased the rates of growth of NAEP reading scores?
Study 1. Conclusions about the comparisons of rates of gain for roughly five years before NCLB started in 2002 with the rates of gain during the NCLB years.
Table 9: Gain Rate Comparison Summary era with rates during NCLB years: Rate differences < [0.3] points per year = 0: Rate differences >0.3 favoring Post NCLB = +. Rate diff. > 0.3 favoring Pre NCLB = -.
Table 10. Estimated gains or losses in NAEP scores from 2002-2012 derived by extrapolating from 2002-2007 data compared to NAEP scores rates of gain from 1998-2002. The numbers are grade levels (gl). The number -0.4 gl means that students would gain 4/10s of a grade level less from 2002-2012 if they continued at their 2002-2007 gain rates than they would if they gained at the 1998-2002 rates.
