Career portfolios are used to plan, organize and document education, work samples and skills. People use career portfolios to apply to jobs, apply to college or training programs, get a higher salary, show transferable skills, and to track personal development. They are more in-depth than a resume, which is used to summarize the above in one or two pages. Career portfolios serve as proof of one's skills, abilities, and potential in the future.Career portfolios are becoming common in high schools, college, and workforce development. Many school programs will have students create, update, and use a career portfolio before moving on to the next level in life.
