Many community colleges have open admissions policies, meaning that anyone who can benefit is welcome to attend. There are usually minimal qualifications for admission to degree and certificate programs; however, some programs "especially in the allied health sciences" are highly selective, have rigorous admissions criteria, and accept only a small number of students each year.
You will need a high school diploma or a high school equivalency certificate based on the General Educational Development (GED) test to take courses for credit. Many non-credit courses are generally open to anyone who wants to enroll.
Students take assessment and admitted placement tests to determine their appropriate class level. Basic skills or developmental courses, plus English language classes, may be required prior to enrollment in college-level courses for credit
