Baby Baby DARLING You’re the WEST!

So I decided to see how the charter sectors of the Top 10 rated charter laws in the National Alliance for Public Charter Schools would look in a cohort gain chart compared to the Cactus Patch. The top ten (in order) are Indiana, Colorado, Washington, Minnesota, Alabama, Mississippi, Maine, DC, Florida and Kentucky. The above chart shows 4th grade math and reading scores from 2013, and then 8th grade math and reading scores from 2017-when the 4th grade cohort from 2013 were 8th graders.

Sadly of these states NAEP only reports charter student scores for Colorado, DC, Florida and Minnesota. You have to have a minimum number of students before the NAEP will report scores, and mind you that you can find male Asian scores in some states. It’s a mixed bag with the non-reporting states- some of the laws are old and just not very active in producing “charter schools” (Indiana) and others are young and not very active at producing charter schools (Washington, Alabama, Mississippi, Maine and especially Kentucky). When they do open schools they are going to be AMAZING– as in I’ll have to extend the axis scales on these charts. For now I’ve included them clearly in the above charts as very dark dots. What? Can’t see them? Not to worry just squint hard and use your imagination.

I’m fond of the charter sectors in all of the remaining top 10 states (i.e. the four with actual schools) in different ways. Colorado is a fellow member of the Wild West, Florida is an honorary member, DC charters clearly do better than DC districts despite getting about half of the funding and few of the families with both parents having law degrees, and Minnesota kicked off the charter school movement.

I think that all of these charter sectors have majority minority student populations with the exception of Colorado. I’ll let you decide whether Colorado’s higher 4th grade scores or Arizona larger gains and higher 8th grade scores qualifies as most impressive, but either way darlings you’re the west best!

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?

Can you dig it?!?

CAN YOU DIG IT?!?!?!?!
