* High school transcripts: These show all courses taken, grades received, and GPA. Some colleges may also request information from middle school if there are significant academic concerns or achievements.
* Standardized test scores (often): SAT, ACT, or other standardized tests are often required, though this is changing at many colleges.
* Course descriptions/catalog: Colleges want to understand the rigor of the high school curriculum. A course catalog helps them contextualize grades and assess the student's academic preparation.
In short, the information sent covers the entire secondary education experience, aiming to give a comprehensive picture of the applicant's academic capabilities and progress.
