(Guest Post by Matthew Ladner)
So the data went live at midnight EST. The national data is basically flat on all four tests. Most single cycle differences are not statistically significant, so I’m looking at longer periods of time, but the 2015 to 2017 champ looks to be Florida. More details on this later but I’m resisting the temptation to bring Sally back pending further analysis…but only barely!
The short run (2015 to 2017) state level data doesn’t look terribly exciting. I’m still digesting the longer run state level data, but up top there’s a chart to tide you over. NCLB required all states to take math and reading NAEP starting in 2003, so here is the full period (2003 to 2017) gains for 8th grade math and reading by state. These are numerical gains subtracting 2003 from 2017 scores by state.
The 2003 to 2017 period is a natural one to examine, but so too is the post 2009 period, for a few different reasons. The 2009 NAEP happened both in the early days of the Obama administration and during the outset of the Great Recession. NAEP redid the 4th and 8th grade science exams that year. The inclusion of “non-tested” subjects is healthy in my view given concerns over curriculum narrowing. According to my bleary eyes two states have made statistically significant gains in all six exams for the entire available period- Arizona and Mississippi. For the 2009 to 2015 period it had been AZ alone. Arizona and Mississippi were also the only states to make statistically significant gains on all of the math and reading tests during the 2009 to 2017 period. Several states however had statistically significant gains in 3 out of 4 of the math and reading exams between 2009 and 2017-including California, Hawaii, Indiana and Wyoming. On the downside, I have not yet added up the number of significant statewide declines in scores during this period, but there are many of them.
Arizona had three flat aggregate statewide scores and a decline in 4th grade math between 2015 and 2017. At first blush Arizona and Colorado charter schools crushed the academic ball again in 2017, will dig further into details/subgroups but for now:
There is more good news in statewide charter sectors, haven’t touched the TUDA yet, stay tuned.
