What documents do universities require, especially regarding transcripts like the twelfth grade transcript for a Master's?

Most U.S. universities require official transcripts from all post-secondary institutions (colleges and universities) you have attended when applying for a master's program. These transcripts must show all courses, grades, and the grading scale, and should be issued directly by your institution with an official seal or signature.

Twelfth-grade (high school) transcripts are usually not required for master's admissions. The primary focus is on your undergraduate academic records. Rarely, a university may request additional documents, so requirements can vary.
