A CV (curriculum vitae) is a document that outlines an individual's educational and professional experience and skills. There are different formats for a CV, including chronological, functional, and chrono-functional. The chronological format lists experience in reverse chronological order and is commonly used in corporate settings. The functional format focuses on skills rather than dates and is useful for those with gaps in employment. An effective CV includes sections for contact information, education, work experience, research experience, honors and activities, and references. It should be tailored to the specific job or program being applied to and maintained regularly.
