The HESI A2 Anatomy and Physiology (A&P) subtest is a critical component of the Health Education Systems, Inc. Admission Assessment exam. This comprehensive examination is specifically designed to evaluate the scientific knowledge of students applying to nursing and allied health programs across the United States. It acts as a gateway, ensuring that prospective students possess the foundational understanding of the human body necessary to succeed in a rigorous medical curriculum. Whether you are aiming to become a Registered Nurse or pursue another vital healthcare role, mastering this content is a pivotal first step toward your professional future.
While the full HESI A2 covers multiple academic areas, the Anatomy and Physiology section focuses exclusively on the structures and functions of the human body. This encompasses a broad spectrum of medical terminology and systemic biology. You will need a thorough understanding of all major body systems, including how they interact to maintain life.
Key areas covered include basic cellular biology (such as osmosis, mitosis, and metabolism), histology (tissues), and the primary systems: skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive. The questions test not just your ability to memorize names but your understanding of physiological processes and feedback loops.
When you sit for the Anatomy and Physiology portion of the HESI A2, you will encounter a digital, multiple-choice format. Typically, this specific section consists of approximately 25 to 30 scored questions. It is important to note that the A&P subtest is usually part of a larger, composite testing session that has a total time limit, often around 4 to 4.5 hours. While there isn't a strict time limit per question, you must manage your time efficiently across all required sections.
The passing score requirements are determined by the individual nursing school or healthcare program to which you are applying. Most competitive programs require a subtest score of at least 75% to 80%, though some may have higher or lower thresholds. Always verify the specific score requirements with your target institution.
Preparation for the HESI A2 Anatomy and Physiology exam requires an active and multifaceted study approach. Because of the sheer volume of material, starting early is essential. Begin by taking a comprehensive practice test to identify your baseline knowledge and pinpoint specific weak areas. Dedicate focused study blocks to one system at a time, using diagrams to visualize structures and explaining physiological processes out loud to reinforce retention. Consistent repetition of high-yield practice questions is the most effective way to become familiar with the phrasing and difficulty level of the actual exam.
Regarding the testing location, the HESI A2 is administered through Elsevier’s Evolve portal. The specific exam centers are designated by the institution you are applying to. It may be taken at the school’s physical testing center, through authorized proctoring services like Prometric, or, in some cases, via a remote proctoring system. You must check with your prospective school for precise registration instructions and to confirm whether they require a physical or remote testing environment.
Successfully mastering the HESI A2 Anatomy and Physiology test is the key that unlocks admission into the essential healthcare training programs needed for numerous rewarding careers. By proving your proficiency in this foundational subject, you place yourself on a direct path toward the following professional roles:
Registered Nurse (RN)
Licensed Practical Nurse (LPN/LVN)
Dental Hygienist
Physical Therapist Assistant (PTA)
Occupational Therapy Assistant (OTA)
Surgical Technologist
Radiologic Technologist
