Recommendation letters — building the relationships that produce them, years before they are needed.

Of all the elements of a U.S. college application, the recommendation letter is the hardest to fabricate at the last minute. Its quality depends almost entirely on how well the recommender actually knows the student. Many Taiwanese students do not begin to think about this until September of senior year, by which point it is generally too late — what they will receive is a serviceable but generic letter. This piece explains how to build the relationships that produce useful letters, starting much earlier.

Why recommendation letters carry weight

Admissions officers at top U.S. universities read tens of thousands of applications a year. Among the elements of any given file, the recommendation letter is one of the few that introduces an outside voice testifying on the applicant's behalf. A strong letter does what GPA and the activities list cannot: it describes the texture of how a student thinks in classroom discussion, how they handle setbacks, what their effect on classmates is, and the personal qualities that cannot be quantified but matter enormously.

A vague, generic letter — one that essentially repeats the transcript — adds nothing, and may carry a quiet negative signal. If this student is really so strong, why is this the best letter their teacher could write?

Who should write your letters

U.S. universities typically request two or three teacher letters plus one from a school counselor. A few principles for choosing recommenders:

Choose teachers who actually know you, not teachers with the most prestigious titles. A regular-subject teacher who has taught you for three years and can describe your growth in detail will write a more persuasive letter than an AP teacher who knows nothing about you beyond your grade.

Match the subject mix to your intended field. STEM applicants typically benefit from one STEM teacher and one humanities teacher. Humanities and social science applicants are often well served by one in-field teacher and one who can describe overall intellectual character.

Consider the teacher's English writing ability. Letters must be written in English (some schools accept Chinese letters with translation, but the English original is the standard). In Taiwan, some teachers' English writing may be limiting. Where this is the case, you can support the teacher (described below) or choose a different recommender.

Building a recommendation-worthy relationship

The quality of a letter is downstream of the substance of your interaction with the teacher. Some specific practices:

Engage seriously in class. Participate in discussion. Ask questions with real depth — not "how do I solve this," but "how does this idea relate to what we read in another unit?" or "is there a counterexample to this argument?" Make the teacher's understanding of how you think visible.

Visit after class. Stop by office hours or stay after to discuss the day's material or related reading. This is not a tactical maneuver — it is also how learning actually deepens. When a teacher later writes your letter, they are drawing on dozens of these exchanges, not on the grade column.

Let the teacher see your life outside class. If you are doing meaningful work in an area adjacent to this teacher's subject, share it. Not to brag — to give them substantive material to draw on in the letter.

Show real growth in your work. What teachers remember best are moments of genuine intellectual movement — a breakthrough on a difficult concept, a substantial step up over a year of papers. Let your learning be visible in process, not just outcome.

When and how to ask

Timing. The ideal moment to ask is at the end of eleventh grade, before summer. This gives the teacher the entire summer to think and write, while memories of you are still fresh. No later than early September of senior year.

Approach. Do not just email "I need a recommendation letter." Sit down with the teacher in person. Explain the kinds of schools you are applying to, the through-line of your application, and the specific qualities you hope the letter can illuminate. The conversation itself is part of how the teacher learns how to write a useful letter.

Provide a brag sheet. Give each recommender a packet containing your résumé, activities list, school list, and a one-page note on the moments or assignments in that teacher's class that you feel best represented you. You are not ghost-writing the letter; you are providing the raw material from which a specific, persuasive letter can be drawn.

A note for Taiwanese students

In the Taiwanese high school structure, teachers handle large numbers of students, and one-on-one interaction is harder to come by than at U.S. high schools. Taiwanese students therefore need to be more deliberate about creating the moments of substantive engagement that produce strong letters. Sustained, sincere effort over time is the only way to overcome this structural constraint.

For teachers whose written English is limited, offering a detailed Chinese-language draft of the substantive content — and then asking whether professional translation support would be welcome — can be helpful. Some U.S. universities, particularly those with significant Taiwanese applicant populations, are also open to bilingual letters.

In the end, a strong letter is a record of a real relationship. No technique can substitute for that. The earliest reasonable investment in these relationships is among the most consequential decisions a high school student can make for their application.
