What are the basic requirements for license renewal in Virginia?

Regular licenses must be renewed every five years. To renew the license, the individual must obtain at least 180 points through a series of 10 professional development options. License holders without a master's degree must earn at least 90 points by completing a three-semester-hour course at an accredited two or four-year college in the content area listed on the license. During one five-year cycle, the license holder may be granted approval to take course work in special education, English as a second language, gifted education, or technology education in lieu of the three-hour content course. In addition, professional development activities designed to support the Virginia Standards of Learning, Standards of Accreditation, and Assessments may be accepted in lieu of the content course for one renewal cycle.
