Gains and Not So Much, II

Delving further into Jim Weigand’s report that his Super is bragging on the year-to-year SOL performance in Lynchburg: The problem is the absence of data on the new retest rate that raised pass rates by about 4% in 2015.  So let’s look at the 2014-2015  changes in pass rates v. the state average, which at least discounts the Lynchburg score gains by the statewide equal opportunity for grade inflation.

Here, for a start, are the five-subject pass rate changes by race and economic disadvantage (“Y” = economically disadvantaged as reported in the VDOE database; “N” = not).

On the five-subject average, the Super gets bragging rights for the non–ED white kids, with a 1.4% score gain over the state average; otherwise he has some explaining to do, especially as to the ED white students, who improved by 3.9% less than the state average.

On the reading tests, the opportunity for bragging rights doubles by the addition of the black, economically disadvantaged students.  But the score gain by the white, ED population lags by 2.5% and the black, not-ED by 2.9%

Finally, on the math tests, the Lynchburg Super gets full bragging rights, especially as to the black, ED students.

Looks to me like Lynchburg needs figure out what its math teachers are doing and spread some of that to the teaching of the other four subjects.
