Indiana’s A-to-F school grades may say a little about whether schools are effective, but they appear to say a lot more about how many poor children attend the schools.
The 2013 grades, approved recently by the Indiana State Board of Education, track pretty closely with the percentage of children who qualify for free and reduced-price school lunches. The fewer poor kids, the higher the grades, and vice versa.
This is no surprise. Matthew Di Carlo of the Shanker Institute showed it was the case with his analysis of Indiana’s 2012 school grades. And a look at the 2013 grades shows not much has changed.
Like Di Carlo, I divided Indiana schools into four equal-sized groups according to their percentage of free and reduced-price lunch (FRL) students, then looked at the number of As, Bs, etc., in each group. (He used only elementary and middle schools; this analysis includes all schools with grades and FRL data).
A few highlights:
- Among low-poverty schools, nearly three-fourths got As and almost nine of 10 got As or Bs.
- Low-poverty schools were three-and-a-half times as likely to get an A as high-poverty schools.
- Barely 2 percent of low-poverty schools got Ds and Fs; among high-poverty schools, 42 percent got Ds and Fs.
- Low-poverty schools were nearly 40 times more likely to get an A or B than a D or F; high-poverty schools were more likely to get a D or F than an A or B.
- 79 percent of all Fs went to schools in the high-poverty group.
