A CV, or curriculum vitae, is an overview of a person's professional life and skills. While more commonly referred to in Europe, the American equivalent is called a resume. A resume or CV is essential when job hunting. For some jobs, fluency in one or more foreign languages is necessary. There is a way to mention language skills on a CV to get better results.
Create a section on the CV entitled "Language Skills" or "Foreign Language Skills." Put the heading in bold type so it stands out. This is the section that follows the education section of the CV. The language skills section briefly describe your language skills -- reading, speaking and listening.
List the foreign language you are fluent in first. Include your level of proficiency. For example, write "Italian (fluent in speech, writing and reading)."
List other foreign languages you are skilled in and include level of skill. For example, write "Russian (proficient in speech, competent in writing and reading)."
Keep in mind there are a wide variety of ways to present your work history and skills in a resume.
Do not exaggerate you language skills. Be honest on your CV or resume because you may be tested.
