If at first you don’t succeed, hope for some help. In this case, after I posted the 2014 data thinking they were 2015, Steve Fuhrman emailed to say that VEA has the 2015 Required Local Effort (“RLE”) data posted. Indeed, they do. Indeed, so does VDOE. Somehow I pulled up the previous year’s data last time I tried.
Turning to the data, we again have some caveats: The RLE data again include both Emporia and Greensville County, Fairfax City and County, Williamsburg and James City County but the SOL data combine each of those pairs. I’ve deleted Emporia, Greensville, Williamsburg, and James City. The Fairfax RLE data are close (116 for the County, 103 for the City) and the County is so large that it should swamp any difference in pass rates so I’ve included the County RLE excess and the County+City pass rates.
As well, the VEA data show Lee County with no numbers and as “Resubmission Pending” so I’ve deleted Lee County.
To the good, we have Accomack County this time.
With those changes, here are the 2015 division reading pass rates plotted vs. the 2015 Expenditure for Operations excess over the Required Local Effort.
As a thank you to Steve, the green diamond is Charles City County.
The gold square is Richmond. The red diamonds are the Richmond peers, from the left Norfolk, Newport News, and Hampton.
The median excess RLE is 77%. The two high-spending, high-scoring divisions are West Point (284% excess RLE) and Falls Church (196%).
The least squares fitted line suggests that doubling the RLE increases the pass rate by about 2% but the 1.7% R2 tells us that the pass rate and excess RLE are essentially uncorrelated.
Here are the data for the remaining subjects and the five subject average:
Finally, with the omissions noted above, here are the five subject data. I made the upper case entries in the RLE list (e.g., Roanoke CO) to force it to sort the same way as the SOL list.
