In the United States, a CV is almost exclusively limited to professions in academia, science and medicine. In the case of academia, the main focus of the CV should be to identify yourself as a scholar. The added length, should be filled with proof of your skills as a teacher, scholar, and your knowledge of education. A CV should be thought of as a living document, and it will change frequently based on the updates in your education and career.
Work Experience. This section should include all relevant paid work experience, including internships. Volunteer or charity work should not be included in this section, or often at all (see below). Make the title of this section a reflection of your paid experience: “Work Experience”, “Employment History”, and “Work History” are all appropriate titles. This should be listed above “Education” unless you are a recent college graduate, since that information is most pertinent to employers.
