For reference, Virginia uses the Standards of Learning (SOL) tests to evaluate the quality of public school education. This test measures students' academic achievement in reading, writing, math, science, and social studies, and is used as a key criterion for assessing each school's performance.

Additionally, the Virginia Department of Education (VDOE) monitors students' academic progress through the Virginia Assessment Program, which determines the accreditation status of schools based on this data. These assessment results are made public to parents and the community, serving as important references for school choice and educational policy decisions.

You can easily check the evaluation results of local schools on the websites of each local school district. For example, visiting the websites of Fairfax County Public Schools or Prince William County Public Schools will provide you with detailed information.

Through this evaluation system, Virginia continuously monitors students' academic achievement and strives to maintain and improve the quality of education in schools.
