Key Insights
This shows the breakdown of the around 2000 schools that were given in the data sets into elementary, high, and middle school. As you can see the number of elementary schools far outweighs the number of high or middle schools by about four times as many schools. However, both the number of high and middle schools in Virginia are extremely similar, both hovering around 300.
The distribution of Free/Reduced Lunch for Virginia schools is normalized about 50%, with there being a few more schools with a percentage less than 50 than those with a higher percentage. The percentage of students on a free or reduced lunch plan is important to understanding inequality in Virginia’s school system because if a school has a higher percentage of students on free or reduced lunch, then it most likely means that the area surrounding that school are less affluent.
Viewing the accreditation status of schools broken up by level acts as an overview for overall school performance across Virginia. A majority of schools maintain a fully accredited status, hovering around 80% for all levels of schooling. The percentage of partially accredited schools is about 20% across all levels. Finally, the percentage of schools who were denied accreditation is overwhelmingly small, with it being close to only 3%. This chart shows that schools in Virginia have differences in there performance in all levels of schooling.
