The process of enrolling in a college or university, which often includes registering for classes and completing necessary paperwork.
After completing high school, she looked forward to her matriculation at the university.
Matriculation is formed from "mater" (meaning mother) and "-culum" (a suffix indicating a process or result). The term originally referred to the process of being enrolled in a university, akin to being 'mothered' into the academic community.
Think of 'mother' ('mater') nurturing students as they begin their academic journey, which helps you remember that matriculation is the process of enrolling in a school or university.
