Even in the area's highest performing districts, test scores can vary widely among students, particularly when grouped by income. These charts show the extent to which poverty (based on free/reduced lunch eligibility*) relates to proficiency rates on state exams (chart 1); and compare how lower income students perform relative to their more affluent peers within individual districts and charter schools (chart 2).

* In the first chart, for most districts and charter schools, the free/reduced lunch rate listed is based on the percentage of reportable test-takers receiving subsidized lunches. For several high-poverty schools, the exact percentage of students who qualify was not available for the the 2014-2015 school year because those schools adopted the federal Community Eligibility Provision, which allows all students in a school to receive free lunches. Because household applications to determine subsidized lunch eligibility were not collected, the free/reduced lunch rate listed in those districts and charter schools is from the 2013/2014 school year. In the second chart, because all students in CEP districts receive free lunch, there is no peer group to compare them to.
