POSTECH LOGO

There is no prescribed format for the Medium of Instruction (MOI) letter. To be considered for an English proficiency test exemption, the MOI letter must be issued by the applicant’s high school and clearly state that the entire high school curriculum was taught in English.

MOI letters issued by institutions for post-secondary education are NOT accepted. The letter should be issued on the school’s official letterhead with an official seal or stamp and include the name, title, and contact information of the issuing official for verification purposes.

The submission of an MOI letter does not automatically qualify an applicant for an exemption. The exemption is determined based on a review of the submitted documents.

We recommend submitting the school’s official School Profile or other supporting documents, particularly if the school uses multiple languages of instruction, as these may provide additional context regarding the curriculum and language of instruction.

Please carefully review the [Important Notes] before proceeding with your application on the Study in Korea website. The [Important Notes] provide important information regarding application submission, modification, payment, and other system-related matters.

You can also access the [Important Notes] at any time during or after completing your application by going to My Page > Study Abroad Application Records > My Online Study Abroad Application Information and clicking [Precaution].

No. On the Study in Korea online application system, an examination number may be assigned when you submit your online application, before payment of the application fee.

Receiving an examination number does not mean that your application has been completed. Applicants must complete payment of the non-refundable, non-waivable application fee to finalize their online application.

No. Submitted hardcopy documents following a preliminary or final admission offer, including originals and notarized hard copies, will not be returned, regardless of the admission or enrollment decision. Applicants should not submit original underlying documents that cannot be replaced or re-issued.

In extremely exceptional circumstances where an underlying official document, such as a graduation certificate or academic transcript, cannot be replaced or re-issued and the relevant authentication authority does not permit any alternative form for Apostille or Korean Consular Authentication,

applicants must contact the Admissions Office BEFORE submitting the document and provide official and verifiable documentation from the relevant authentication authority confirming the circumstances. Documents submitted without prior consultation will NOT be returned.

• Does the Apostille or Korean Consular Authentication itself have to be original?

If an official document to which Apostille or Korean Consular Authentication applies, such as a graduation certificate/diploma or academic transcript, cannot be replaced or re-issued due to the policy of the issuing institution or the relevant national authority,

applicants should first consult both the issuing institution and the relevant authentication authority to determine whether an alternative version of the same document with equivalent validity can be issued and authenticated (Apostilled or Korean Consular Authenticated) through the appropriate procedure.

Applicants should not submit an original document that cannot be replaced or re-issued without first confirming that an acceptable alternative can be issued and authenticated, as submitted documents will not be returned.

[Please also check:]

• Does the Apostille or Korean Consular Authentication itself have to be original?

• Will my submitted hardcopy documents be returned?

Yes. Even if a notarized or certified copy of an underlying academic document, such as an official graduation (or expected graduation) certificate or an official academic transcript, is accepted by the relevant authentication authority, the Apostille or Korean Consular Authentication itself must be original and valid.

Notarized or certified copies of the Apostille or Korean Consular Authentication are not accepted.

Cancellation or refund requests submitted through the application system will NOT be processed.

Applicants who pay by bank transfer must email the required proof of payment immediately after making the payment.

As payment may take 1–2 business days to be reflected and confirmed, applicants are strongly advised NOT to make payments on the final day of the application period.
