A portfolio is a collection of your work, the representation of what you’ve accomplished in your field. As such, portfolios can be used in school, work or for hobbies. A college application might require a portfolio, and a job application in an artistic field will almost certainly require a portfolio. PowerPoint is useful in collecting visual portfolio media in a format that can be shared easily. If your portfolio consists of pictures, video or audio clips, then making a portfolio in PowerPoint can showcase your skills.
