Creating a Career Portfolio. An ability to communicate your career skills and experiences is the foundation for obtaining employment. A career portfolio can provide tangible evidence of your experiences and competencies. This collection of artifacts may include a résumé, cover letter, and answers to sample interview questions. Letters of recommendation, research reports, presentations, creative works, and published articles for class projects or campus activities can effectively communicate your abilities. Describe an item from a class project or work setting that you might include in your career portfolio.
