Part of the learning process is reflecting on your work. Many teachers in high school, as well as professors in college, will ask you to write a reflective letter or essay at the end of a semester or before graduation. The goal of this letter is to demonstrate not only what you have learned in a course or throughout your time at that school, but also to demonstrate that you have a clear understanding of the quality of the work you have produced. Another goal of the reflective letter is to discuss where you must continue to improve after the course is finished or after you have graduated.
