Recommendation Letters: Who to Ask, How to Ask, and How to Follow Up (2026 Consultant Field Guide)
Published on March 20, 2026
Recommendation letters are the one document in the Common App that you **cannot fully control** - but you can control who writes them, what information you give teachers, and how you follow up. This article breaks down 12 strategic decision points from 15 years of hands-on experience.
Recommendation Letters: Who to Ask, How to Ask, and How to Follow Up
Published on May 14, 2026
Every September, I receive anxious messages from parents: "The teacher said, 'I'll write the recommendation letter' - but now it's October and it still hasn't been submitted! What should we do?"
My answer is always: "A teacher saying 'I'll write it' and a teacher submitting it on time are two different things. You should have started tracking it on September 1. If you wait until October, you are already late."
Parents get even more anxious: "Will my daughter's physics teacher write a weak letter if they are not that close?"
The answer is: the quality of a recommendation letter written by a Taiwanese teacher depends on how much information you give them. Drawing on 15 years of field experience, this article breaks down 12 strategic decision points for recommendation letters.
1. The Structure of Common App Recommendation Letters
Common App recommendation letters fall into 3 categories:
Category
Required
Quantity
Counselor Letter
Required
1
Teacher Evaluation
Required
2

Other Recommender
Optional
0-2
The truth: the 3 recommendation letters account for roughly 5-10% of the application evaluation - less than the Personal Statement and Activities, but they have a "bimodal effect":
Strong recommendation letters -> significantly elevate the quality of the application
Weak / mediocre recommendation letters -> reduce the perceived quality of the application
Your overall performance at school (GPA, course rigor)
The school's background (size, characteristics, average academic performance)
Your relative standing among classmates ("top 5 in class of 200")
Your personality / extracurricular activities
Any "context" (if your grades dropped, or if your family had difficulties)
2.2 The Counselor Role in Taiwanese High Schools
School Type
Counselor Setup
American school / international school
Dedicated college counselor (works with 60-100 students per year)
International division
Some have dedicated counselors; some rely on homeroom teachers
Regular high school
Usually handled by a homeroom teacher or administrator (no dedicated college counseling)
The truth: Counselors at Taiwanese public high schools often have never written an English recommendation letter - this is one of the biggest obstacles in U.S. applications.
2.3 What If There Is No Dedicated Counselor?
Option
Details
Ask the homeroom teacher who knows you best
Draft the content in Chinese -> translate into English -> teacher signs
Hire an external Counselor
Consulting firms such as Dr. G. provide counselor service
Ask the principal / director
Suitable when the school has a special background or context
Important: The Common App system automatically identifies "what position the Counselor holds at the school" - so using a "Vice Principal" or "Director of Academic Affairs" carries more weight.
3. Teacher Evaluation: 2 Subject Teachers
3.1 Who Should You Ask?
My 4 principles for Dr. G. students:
A teacher who taught you in 11th grade: 12th-grade teachers have known you for too little time; 9th-10th grade teachers knew you too long ago
A core subject teacher: STEM applicants should ask Math / Physics / Chem / CS teachers; humanities applicants should ask English / History teachers
Related to your intended major: CS applicants should ask a Math teacher; Pre-Med applicants should ask a Bio teacher
A teacher in whose class you performed well: not "the teacher you are closest to," but the teacher "best able to explain why you are excellent"
3.2 How to Pair the Two Teachers
The most common mistake: both teachers are from the same field.
Intended Major
Teacher 1
Teacher 2
CS
Math (high-rigor course)
English (do not ask a second Math teacher)
Engineering
Physics or Math
English / History
Pre-Med
Bio or Chem
Eng Lit / Eng Lang
Business
Math AB/BC or Econ
English / History
Humanities
English Lit
History / Foreign Lang
Pre-Law
History or English
Math or Econ (avoid two humanities letters)
Why must you cross fields? AOs want to see your combined "STEM + humanities" ability - recommendation letters from only two STEM teachers will be read as "lopsided strengths."
4. When and How to Ask for Recommendation Letters
4.1 Timing: May of 11th Grade
The standard timeline I give Dr. G. students:
Time
Action
April of 11th grade
Decide internally on the 2 teachers you want to ask
May of 11th grade
Formally ask the teachers to write
June of 11th grade
Give teachers the "Brag Sheet" information
July of 11th grade
Teachers can write slowly over the summer
August of 11th grade
Send teachers the invite link after Common App opens
September-October of 11th grade
Follow up and confirm progress
11/1 of 11th grade
ED deadline: teachers submit
Why ask in May? Because:
Teachers have time to write during summer break (they are too busy during the semester)
Your 11th-grade performance is still fresh in the teacher's mind
Giving 6 months of advance notice is basic courtesy
4.2 What to Say When You Ask
Wrong example:
Teacher, I want to apply to U.S. colleges. Can you write me a recommendation letter?
Correct example:
Teacher, I plan to apply for undergraduate programs in the U.S. You taught me physics this year, and I was also your TA in chemistry the year before last, so you are the teacher who has taught me the longest and understands my academic ability best. Would it be possible for you to write a recommendation letter for me by September 1? I will prepare a complete information packet for your reference.
Key points:
State the specific deadline
Mention specific shared experiences (to help the teacher remember you)
Promise to prepare materials (so the teacher knows you will reduce their workload)
Leave time for the teacher to consider / decline
5. Brag Sheet: The Key Information Packet for Teachers
The biggest secret: the more information you give teachers, the stronger the recommendation letter will be.
5.1 What Should a Brag Sheet Include?
Section
Content
Basic Information
Your name, student ID, GPA, target school list
Interactions with the Teacher
Courses taken, projects completed, specific conversation memories
Academic Achievements
Competitions, self-study, research in the field
Extracurricular Activities
Activities related to the teacher's field
Personality Stories
1-2 specific events that show your character
Goals
What major you want to study and why
Special Context
Family, culture, health (if there is a special need)
5.2 Brag Sheet Template

6. How Long Should a Recommendation Letter Be?
Typical recommendation letter length:
Length
AO Reaction
< 0.5 page
"This teacher does not know the student at all" -> negative
0.5-1 page
Neutral; this is where most teachers land
1-2 pages
Positive; the standard for a serious letter
2-3 pages
Strong recommendation; the teacher truly loves this student
> 3 pages
Too long and may backfire
Main point: 1-2 pages is the sweet spot. The more complete the Brag Sheet, the easier it is for the teacher to write 1-2 pages.
7. English Letters from Taiwanese Teachers: How to Handle Them
Many Taiwanese high school teachers are not comfortable writing in English - but the recommendation letter must be in English. There are 3 ways to handle this:
7.1 Teacher Writes in Chinese -> You Translate -> Teacher Signs
This is the most common method. Note: your translation cannot change the teacher's original meaning, or it violates Common App rules.
7.2 Use AI-Assisted Translation + Teacher Review
Teacher writes in Chinese -> use ChatGPT to translate -> print it for the teacher to review -> teacher signs only after approving it.
7.3 Hire a Professional Translator
Consulting firms such as Dr. G. provide recommendation letter translation and editing services.
The truth: AOs know that many international students' recommendation letters are "translated versions" - as long as the content is truthful, it is OK. The Common App system even has a checkbox for "translated documents."
8. Other Recommender: Supplemental Recommendation Letters
Common App allows 0-2 Other Recommender letters - recommenders who are not subject teachers.
8.1 Suitable Other Recommenders
Person
Suitable Scenario
Research supervisor
You completed summer research / an internship
Club advisor
The supervisor for your club / volunteer activity
Coach
Sports / orchestra / competition coach
Employer / internship supervisor
You have real work experience
Pastor / religious leader
You are active in a religious community
8.2 The 3 Principles for Other Recommenders
Do not seek famous people just for prestige: "Nobel Laureate who does not know you" < "Lab PI who has known you for 2 years"
They must add an angle not covered by subject teachers: for example, leadership, research depth, or personal character
Do not exceed 2 letters: 3 or more letters = "trying too hard to squeeze in recommendations" = backfires
9. The 3 Follow-Up Points for Recommendation Letters
A teacher agreeing to write does not mean the teacher will submit on time. This is the follow-up schedule I give Dr. G. students:
Time
Action
September 1
Send the teacher the Common App invite link + remind them of the deadline
September 30
Send a polite email: "Dear Teacher, this is just a reminder that the ED deadline is 11/1"
October 15
If the teacher has not moved, go to the office in person to confirm progress
October 25
If the teacher still has not submitted, ask the Counselor to help follow up
11/1
Final deadline - most schools allow teachers to be 1-2 days late
The truth: 30% of Taiwanese teachers will delay recommendation letters. Proactive follow-up is the student's responsibility, not the teacher's responsibility.
10. What If the Recommendation Letter Is "Too Generic"?
If you see a teacher's draft recommendation letter (Common App policy prohibits students from seeing the final version, but there are exceptions involving the Counselor / FERPA Waiver) and feel that it is too generic, you can:
Solution
Details
Add new information
Give the teacher 1-2 recent specific achievements
Switch teachers
November is too late to switch, but September is still possible
Ask another teacher to serve as the 3rd Other Recommender
Strengthen another side of your profile
The most important thing: For the FERPA Waiver, you should select "I waive my right to view the recommendation letter" - when AOs see "student waived the right to view," they will trust the letter more.
11. What If You Get Rejected? What If the Teacher Refuses to Write?
In a small number of cases, teachers will refuse. Possible reasons:
Reason for Refusal
How to Handle It
The teacher has no time
Ask another teacher
The teacher has never written an English recommendation letter
Provide a Brag Sheet + translation support
The teacher thinks your grades are not strong enough
Reconsider this teacher - they may write negative content
The teacher feels they do not know you well
Use the Brag Sheet to refresh their memory
Warning sign: If a teacher says, "I can write it, but I may not be able to write it well" - switch immediately. It is better to find another teacher than to submit a recommendation letter with a cautionary tone.
12. Conclusion: Recommendation Letters Are Documents You "Cannot Control, But Can Influence"
Over 15 years, I have seen too many parents worry that "we cannot see what the recommendation letters say" - but in reality, 80% of what teachers write depends on the materials you provide + your relationship with the teacher.
My final reminder to Dr. G. students:
A recommendation letter is not about you "asking the teacher for a favor" - it is about you "giving the teacher enough material so they can write the strongest possible version". The more complete the Brag Sheet, the earlier you ask, and the more proactive your follow-up, the higher the quality of the recommendation letter.
Ask in May of 11th grade. Do not wait until September, and definitely do not wait until October.
