CLEP
What is the CLEP?
Students can take CLEP exams to demonstrate proficiency in some college courses. Some colleges accept CLEPs for credit. Others accept CLEPs as evidence that students have demonstrated proficiency in a general education subject (like a foreign language). This may enable students to waive that course in college and replace it with some other elective. Contact your college admissions office for more information.
