Stanford University's Opportunity Explorer is an interactive map which allows you to explore how your school, school district and county compare in educational attainment. The map uses data from over 350 million standardized test scores to show average test scores in areas across the United States and also school learning rates and trends in test scores.
If you click on a school district on the map you can view the district's average test scores and average learning rates and how these two scores compare to the national averages. You can also view in the map side panel the trend in school test performance in the district from 2009-2016 and the average socioeconomic status in the district and how that compares to the national average. An interactive chart also allows you to see how the district compares to national average test scores and the average socioeconomic status.
As well as allowing you to view school test scores at the district and county level the map can also show you learning rates and trends in test scores at the school district and county level. Learning rates show how much students learn each year relative to the national average and the trends in test scores show how students' average test scores changed in grade levels over time.
The Opportunity Explorer also allows you to see how test scores differ in schools, school districts and counties for different types of student. You can explore test scores in schools by race, sex and for poor and non-poor students. Being able to explore the data by race and socioeconomic status helps to reveal how minority students are concentrated more in high-poverty schools, which tend to perform less well than lower-poverty schools.
