What is a Portfolio?
A portfolio is a collection of items organized in a notebook, file, or a similar format. Whether you are applying for a job, internship, or to further your education, you may be asked to provide a portfolio including writing samples. The goal of a writing sample is to measure your ability to write professionally, clearly, and succinctly. The best way to demonstrate this ability is by providing samples in an area relevant to the position for which you're applying. You should include short explanations of the work in your portfolio.
What To Save
Your portfolio will reflect your very best work. To achieve that aim, you will need to revise your work from the comments by your professor, and from your own careful re-reading of your work. You also need to grammatically correct and proofread each sample. Make sure to save a corrected copy in a portfolio folder on your computer.
