What is the best recommendation letter strategy for applying to WashU?

For WashU, the strongest strategy is to submit recommendations from two core academic teachers who know you well and can speak in detail about how you think, learn, and contribute in class. A humanities teacher and a STEM teacher is often the best balance if both can write vividly about your work.

Pick teachers from junior year when possible, because they taught you most recently in a rigorous setting and can comment on your readiness for college-level work. The best recommender is not the teacher from the hardest class or the one with the biggest title, but the one who can give concrete examples of your curiosity, discussion style, writing, problem-solving, initiative, or growth. At a place like WashU, a detailed letter that shows intellectual engagement is usually much more useful than a generic letter from someone impressive.

If one subject is clearly central to your application, it is smart to have at least one recommender from that area. For example, a future engineering applicant benefits from a strong math or science teacher, while a prospective humanities student should strongly consider an English or history teacher. Still, balance matters, and two letters that show different sides of you are often stronger than two letters that repeat the same traits.

Only add an extra recommendation if it contributes something meaningfully new. An arts instructor, research mentor, or supervisor can help if they can document sustained impact, creativity, leadership, or character in a way your teachers cannot. If the extra letter just says you are responsible and nice, it usually does not help.

The practical strategy is simple: ask early, choose teachers who know your work firsthand, and give them a short brag sheet with your activities, academic interests, and a few specific moments from their class that mattered to you.
