Registration for the 2027 College Scholastic Ability Test (CSAT) will take place from August 24 to September 4. Applications will be accepted at 85 regional Offices of Education nationwide and respective high schools. To prevent confusion among test-takers, we have organized key information including the application schedule, methods, required documents, and fees.

• *1. Application Schedule and Hours**
• Online Pre-Entry: August 20, 9:00 AM – September 3, 6:00 PM (available 24 hours)

• *Note:* No late applications or modifications will be accepted after the on-site registration deadline.

2. Application Methods and Required Documents Registration can be completed in two ways: ▲ online pre-entry followed by an on-site visit, or ▲ direct on-site registration.

• For Online Pre-Entry Users: After entering application information on the designated website, applicants must visit the on-site registration location in person to complete identity verification. Online pre-entry requires identity authentication via mobile phone, simple authentication certificate, i-PIN, or joint public certificate. A passport-sized photo file and the examination fee must be prepared in advance.
• Common Required Documents for On-Site Visits: Both online pre-entry users and non-users must bring a photo-bearing ID (resident registration card, driver's license, passport, etc.) when visiting the site. If identity cannot be verified through the ID photo, two additional passport-sized photos must be submitted. Test-takers who do not use online pre-entry must fill out and submit the application form on-site.
