Quick answer: GKS recommendation-letter requirements vary by track and application cycle. For example, the 2026 GKS-U application requires one recommendation letter. Choose someone who genuinely knows your academic ability or character, ask early, give your recommender useful material to work with, and follow the current official instructions for signing, sealing, and submission.
For how the recommendation letter fits into the wider application packet, see the GKS Required Documents Checklist. You can also review the GKS Personal Statement Guide and GKS Study Plan Guide to understand how your supporting documents work together.
Important: Recommendation-letter requirements can change between GKS cycles and may differ by application track. The guidance on this page explains the usual process and common requirements, but your current year’s official GKS guidelines and embassy or university instructions always take priority.
Who Should Actually Write It
The strongest recommender isn’t necessarily the most impressive title — it’s someone who can describe your actual work, habits, and character in specific detail.
Good choices generally include:
- A professor or academic advisor who taught or supervised you directly
- A high school teacher, for undergraduate applicants, who knows your work well
Generally best to avoid:
- A professor at the specific Korean university you’re applying to, if they don’t actually know you — this doesn’t strengthen your application and can read as an attempt to name-drop rather than a genuine recommendation
- Someone with only brief or surface-level contact with you, even if their title is impressive
A recommender who can write specific, detailed observations is more valuable than one whose name simply looks good on the page.
How Many Letters You Need
The number can vary by GKS track and application cycle. For example, the 2026 GKS-U application checklist requires one letter of recommendation. Always check the current year’s official application guidelines and checklist for your specific track before asking your recommender to prepare the document.
What the Letter Should Actually Cover
The official recommendation form generally asks recommenders to address qualities like:
- Ability to work independently or as part of a team
- Intelligence and academic aptitude
- Attitude toward learning and challenges
- Potential for future contribution in their field
- Capacity for cultural adaptation
You won’t write this letter yourself, but understanding what it’s meant to cover helps you choose the right recommender and give them useful material to work with.
How to Ask for a Strong Letter
- Ask well before the deadline. A rushed recommender, even a well-intentioned one, tends to write a shorter, more generic letter than one given real time.
- Ask in person or with a genuine, specific message, not a mass request. Explain briefly why you’re applying and why you’re asking them specifically.
- Give them material to work with: a short resume or CV, a summary of your academic or career goals, and — if you’re comfortable sharing it — a draft or outline of your Personal Statement, so their letter can complement rather than repeat it.
- Provide the deadline and submission instructions clearly, including whether the letter needs to be sealed, signed, and returned to you, or submitted separately by the recommender.
- Follow up with a reasonable reminder as the deadline approaches, without being pushy — a short, polite check-in is normal and expected.
- Thank them, regardless of outcome. They’re doing you a genuine favor, and a brief note of thanks costs you nothing.
Submission Requirements
Recommendation letters are only one part of the application packet, so check the GKS Required Documents Checklist before preparing your final documents.
- The applicant fills in their own information at the top of the official form and gives it to the recommender
- The recommender completes the required recommendation form and letter according to the current application instructions.
- If the current application instructions require a sealed recommendation letter, the recommender should date and sign it and follow the specified sealing procedure, including signing across the back flap where required.
- If your current application instructions require a date, signature, or sealed envelope, missing any of those requirements can make the document invalid.
Some cycles or embassies may instead request electronic submission directly from the recommender. Don’t assume one method applies without checking your specific instructions.
Official Document
The recommendation letter form is one of the numbered forms in NIIED’s official GKS Application Forms packet (the exact form number can shift slightly between cycles).
What it is: A form with a section for the applicant’s basic information and the recommender’s details, followed by space for the letter itself or instructions to attach one.
Why it matters: Use the current official recommendation form and instructions required for your GKS application rather than an old or unofficial template.
When to use it: Give it to your chosen recommender as early as possible, ideally weeks before your actual deadline.
Where to get it: Through the GKS Notice section of the Study in Korea website (studyinkorea.go.kr), or your embassy’s current GKS application packet — linked here rather than reproduced, since the exact form and instructions can change between cycles.
- Official GKS Application Forms: The current GKS application forms are published by NIIED through the official Study in Korea GKS Notice. Applicants should download the form for their current application cycle and follow the instructions provided there.
Common Mistakes
Asking too late. A recommender given only a few days often ends up writing a shorter, less specific letter than one given real lead time.
Choosing someone who doesn’t know you well. A prestigious title attached to a vague, generic letter is weaker than a detailed letter from someone less well-known.
Not giving the recommender enough context. A recommender working with almost no information about your goals is more likely to write something generic. A short resume and goals summary genuinely helps.
Missing the sealing or signature requirement. If your current cycle requires a sealed and signed envelope, failing to follow that instruction can make the recommendation letter invalid or result in the document not being accepted.
Assuming last year’s submission method still applies. Submission requirements can change between cycles — confirm the current process rather than relying on what a friend did in a previous year.
