Also referred to as a cover letter, a letter of introduction includes information about the portfolio's creator, pieces in the portfolio and the purpose of submitting the portfolio. The letter points out to potential employers the job-relevant skills and abilities that the writer demonstrates in the portfolio's pieces.
When writing a letter of introduction for a portfolio, the writer may explain each piece individually to show the background of the piece's creation, what its meaning is (for literature) or the outcomes of the project. For example, the writer may submit a research project and tell in the letter of introduction what questions the project sought to solve and what the outcome was. Some tips are to be specific when discussing a piece, link the pieces to specific goals and keep the letter positive.
