A career portfolio includes a letter of introduction, a detailed resume and a list of professional references. A portfolio also includes samples of the job applicant's work.
The letter of introduction includes personal information about the applicant, an explanation of his skills and the reasons he's qualified for the job. An effective resume showcases the job applicant's past work experiences and recent accomplishments. The references included in a portfolio must be people who are able to confirm the applicant's experience and quality of his work. A portfolio presented to gain employment should also include written or visual samples of the applicant's work.
