Every October, I receive the same anxious message from parents: “Our son’s recommendation letter was reviewed by his Counselor, who said it was too generic and had no specific examples. We only found out in November. What should we do?”
My answer is always: “What the teacher writes depends on the details you gave them in the Brag Sheet back in May. Finding out in October is too late. What we can still do now is add a supplementary letter from another recommender.”
Parents become even more anxious: “Then what exactly should go into a Brag Sheet?”
The answer is: A Brag Sheet is not about “listing your achievements” - it is about “giving teachers concrete stories they can quote.” This article breaks down every detail of recommendation-letter guidance from an essay-consulting perspective.
A recommendation letter has two writers:
Writer | What is visible |
|---|---|
Teacher (visible) | Wording, tone, structure |
Student (invisible) | Materials provided in the Brag Sheet |
The truth: 90% of a recommendation letter’s “specificity” comes from the materials provided by the student. What the teacher does is integrate those materials in their own voice. So the more detailed the Brag Sheet, the stronger the recommendation letter.
Problem: The teacher cannot see “who this student is.” They can only write a generic “strong student” recommendation letter.
Value: After reading this, the teacher can quote specific details from any of these stories in the recommendation letter - “Mr. Lin shared with me his profound experience in mentoring a 3rd grader to write his first Scratch game...” - and that is what makes a recommendation letter strong.
This is the standard Brag Sheet template I give Dr. G. students:
This is the most important part of the Brag Sheet - it helps the teacher remember you:
unknown nodeDo not just list achievements. List “the effort and failure before the achievement”:
unknown nodeIf you have read other articles / papers written by the teacher, you can quote their “voice reference”:
unknown node→ The Brag Sheet is too simple, so the teacher can only write a generic “Strong student” letter.
→ A teacher you only met in 11th grade and have known for 8 months cannot write with depth.
→ Even if the Chinese version is strong, nuance can be lost in translation.
→ Some teachers are used to not overpraising. A moderate sentence like “He is a good student” is not strong enough.
→ The teacher is writing recommendation letters for 20 students at once and has no time to go deeply into each one.
The Counselor is not a subject teacher. They write about the “overall context”:
What the Counselor writes | What the Counselor does not write |
|---|---|
Your rank / percentile at school | Your academic depth |
Course rigor | Specific papers / projects |
Any special circumstance | Academic personality |
School context and your position within it | Your personal qualities |
Tactic: The Counselor Letter and subject-teacher recommendation letters should complement each other. Subject teachers write depth; the Counselor writes breadth.
If you expect your subject-teacher recommendation letters to be insufficiently strong, you can consider adding 1 Other Recommender.
Person | What they strengthen |
|---|---|
Research PI (lab head) | Academic depth + research ability |
Club Advisor | Leadership + continuity |
Coach | Discipline + team spirit |
Employer / internship supervisor | Work ethic + impact |
Do not assume that a PI / coach does not need a Brag Sheet. Every recommender needs one.
Some programs require school- or major-specific recommendation letters:
Scenario | Customization focus |
|---|---|
MIT EA | Emphasize STEM depth + research |
Wharton business school | Emphasize quantitative ability + leadership |
BS/MD 7-Year | Emphasize service + maturity |
Each additional customized recommendation letter requires 1-2 more hours from the teacher. Only ask the teacher to customize when it is truly necessary.
Fatal word | Why it is fatal |
|---|---|
"Adequate" | The teacher’s evaluation of you is extremely low |
"Quiet" / "Reserved" | AOs may read this as “does not like engagement” |
"Average" | An immediate death sentence |
"Sometimes" | Weakens the sentence |
"Tries hard" | “Works hard but lacks ability” |
"Hard-working" used alone | No concrete story supporting it → sounds generic |
Length | AO impression |
|---|---|
< 0.5 page | The teacher does not know the student (negative) |
0.5-1 page | Neutral |
1-1.5 pages | Positive, the standard for a carefully written letter |
1.5-2 pages | Strong recommendation |
> 2 pages | Too long, may backfire |
The more detailed the Brag Sheet, the more easily the teacher can write 1.5-2 pages.
Tool | Purpose |
|---|---|
Common App system | Shows whether Counselor / Teacher 1/2 has submitted |
Excel sheet | Track each recommender’s status yourself |
Email reminders | 9/1, 9/15, 10/1, 10/15, etc. |
Over the past 15 years, I have seen too many students assume that they can simply “ask the teacher to write it.” That is wrong. A recommendation letter is a “joint work by you and your teacher”: you provide the story materials, and the teacher integrates, quotes, writes, and signs.
My final reminder to Dr. G. students:
If you want a strong recommendation letter, you must do 3 things well:1. Ask in May of 11th grade, giving the teacher at least 4 months to prepare2. Prepare a detailed 5-8 page Brag Sheet: concrete stories + interactions with the teacher + the 3 main areas you want emphasized3. Proactively follow up in September / October + send a thank-you note after 11/1
A strong recommendation letter is not “luck” - it is “engineering.” The more detailed your Brag Sheet, the stronger the recommendation letter.
