The Standards of Learning (SOL) is a public school standardized testing program in the Commonwealth of Virginia. It sets forth learning and achievement expectations for core subjects for grades K-12 in Virginia's Public Schools. The standards represent what many teachers, school administrators, parents, and business and community leaders believe schools should teach and students should learn. The Virginia Department of Education, schools, and school systems routinely receive essential feedback on the effectiveness of implementation and address effective instructional strategies and best practices.
