Academic classification refers to the system used to categorize students based on their level of education and progress. This system typically includes classifications such as freshman, sophomore, junior, and senior in high schools and colleges. Each classification reflects the number of credits earned and the expected year of graduation. In addition to student classifications, academic classification can also apply to courses and programs. For example, courses may be classified as introductory, intermediate, or advanced based on their complexity and prerequisites. This helps students understand the level of difficulty and the skills required for each course.
