There are many different paths you can take to becoming a nurse, including three Associate Degrees. But how do you know which is right for you -- the Associate Degree in Nursing (ADN), the Associate of Science Degree in Nursing (ASN), or the Associate of Applied Science in Nursing (AAS)? 

The most common and widely known of the three is the ADN; however, the other two are viable options for individuals interested in becoming nurses. In this article, we’ll explain what the three degrees are, and what the differences are between them. 

ADN vs ASN vs AAS Nursing Degrees: What Are the Differences?

For purposes of being eligible for the NCLEX examination to earn your RN, there isn’t much difference between these types of degrees. However, individuals that are interested in earning their BSN and advancing their nursing degree will fare better earning an ADN degree. BSN programs align better with ADN programs, and there will be less additional coursework required. 

If a student has an ASN or AAS, they will need to complete additional coursework for a BSN degree. Also, not all coursework in an ASN or AAS program is transferable to other programs.

    ASN and AAS programs generally are offered by vocational schools and hospital-based programs. This is NOT always the case, and there are also schools offering these degrees. With these programs, board approval is a major concern. Without BON approval, you will NOT be able to sit for the NCLEX examination which is required to practice as a Registered Nurse. 

    What is an Associate Degree in Nursing (ADN)?

    An Associate Degree in Nursing, or ADN program, is focused solely on nursing core classes and clinicals. Classes focus on the clinical aspect of nursing instead of the leadership, research, and management focus seen in other nursing programs. Students are not required to take courses that are outside of their curriculum, and the program can typically be completed in two years.

    Associate’s degrees in nursing are offered by many community colleges and some four-year institutions. An ADN program will blend hands-on training with classwork. ADN programs are designed to train students in the technical skills needed to become a nurse in an entry-level position and about a patient’s basic health needs.

    Prerequisites Needed for an ADN Program 

    • Microbiology
    • Anatomy and Physiology
    • English
    • Statistics
    • Psychology
    • Chemistry

    Courses You’ll Take in an ADN Program

    Some of the courses you’ll take in an ADN program include:

    • Foundations in Nursing
    • Nursing Care of Adults
    • Behavioral Health
    • Maternal and Child Nursing

    What is an Associate of Science Degree in Nursing (ASN)?

    An Associate of Science Degree in Nursing, or ASN, is also a two-year program that prepares individuals to take the NCLEX examination through a blend of hands-on training and didactic coursework. It is typically offered at vocational schools and hospital-based nursing programs.

    The focus of the program is more on clinical skills than academic work. For this reason, students will spend more time in a skills lab and clinicals than in the classroom. Coursework is roughly 72 credits with a minimum of 41 semester credit hours devoted to nursing courses.

    Which is Right for You -- ADN, AAS, or ASN?
