(Guest Post by Matthew Ladner)
Yesterday we went over how states have done very little to improve in 8th grade math since 2009, but how many state charter sectors rocked it. Let’s see about reading, starting with the states:
There are more declines in scores than statistically significant gains in that first chart-some states more lost than others, but a lost decade nationally. Next let’s look at statewide charter sectors-these are the states with charter sectors large enough to make the sample in both 2009 and 2017 in 8th grade reading:
Once again, just as with math, Excel had to move the growth axis scale for several state charter sectors. You will appreciate this better when the following chart combines statewide averages and state charter sector averages:
So in this chart ideally you would like to see high scores and high gains, but there is no shame in just very high scores.
Can you dig it?
