What is the HESI A2 Entrance Exam?
The HESI A2, or Health Education Systems, Inc. Admission Assessment Exam, is a standardized test widely used by nursing and allied health programs across the United States as a component of their admissions process. It serves as a tool to evaluate the academic readiness of prospective students, aiming to predict their potential for success in rigorous healthcare education programs. Essentially, the HESI A2 assesses a student’s foundational knowledge in core academic areas that are deemed essential for success in healthcare fields.
This examination is designed to provide admissions committees with an objective measure of an applicant’s abilities, supplementing other application materials such as transcripts and personal statements. The exam typically covers several key subject areas, though the specific sections included can vary slightly depending on the institution administering the test. However, common components generally include the following and note that the number of questions and time limits sometimes change with each update to the exam.
Biology:
The Biology section of the exam allows 25 minutes with 25 questions which test basic knowledge of biological concepts, including cell structure, the cell cycle, metabolism, and other fundamental principles. This foundational knowledge is essential for understanding human physiology and disease processes. The HESI A2 Biology section delves into the foundational principles of life, beginning with the very nature of what defines a living organism.
Expect questions that test your understanding of the characteristics of life, such as growth, reproduction, response to stimuli, and homeostasis. You will also be assessed on your grasp of the scientific method, including the steps involved in hypothesis formation, experimental design, data analysis, and parts of a microscope.
A significant portion of the exam focuses on the chemical basis of life, requiring knowledge of basic chemistry concepts pertinent to biological systems. This includes the properties of water, the importance of pH, and the nature of chemical bonds that form biological molecules. Moving into the realm of biological molecules, the exam will assess your comprehension of the four major classes: carbohydrates, lipids, proteins, and nucleic acids. You should be prepared to identify their structures, functions, and roles within living organisms. For example, you might be asked to differentiate between saturated and unsaturated fats, or to explain the functions of various proteins like enzymes and structural components.
The structure and function of cells are crucial topics. Expect questions on the various organelles, their roles within the cell, and how they contribute to overall cellular function. You’ll need to understand the mechanisms of cellular transport, including passive processes like diffusion and osmosis, as well as active transport mechanisms that require energy. Metabolic processes are also heavily featured, with a focus on cellular respiration and photosynthesis. You should be able to explain the steps involved in these processes, including the reactants and products, and understand how they contribute to energy production and utilization within cells. Genetics forms another substantial part of the exam. Expect questions about the structure and function of DNA and RNA, the processes of DNA replication, transcription, and translation, and the mechanisms of protein synthesis.
You will also need to demonstrate your understanding of mitosis and meiosis, the processes of cell division, and their roles in growth, repair, and sexual reproduction. Basic Mendelian genetics, including concepts like dominant and recessive alleles, Punnett squares, and the principles of inheritance, are also likely to appear. Finally, the exam touches upon general biology concepts such as basic ecological principles, potentially covering topics like food chains, food webs, and the interactions between organisms and their environment.

Basic Math Skills:
The math section has 50 questions in 50 minutes and focuses on mathematical skills necessary for healthcare practice, including calculations involving fractions, decimals, percentages, ratios, and proportions. These skills are vital for accurate medication dosage calculations and other essential tasks. Here’s a breakdown of the key topics: Basic arithmetic, including addition, subtraction, multiplication, and division of whole numbers, decimals, fractions, and percentages. Fractions, decimals, and percentages, including converting between these forms and solving problems involving ratios and proportions. Basic algebra, including solving simple algebraic equations and understanding and using basic algebraic concepts. Ratios and proportions, including solving problems involving them. Measurement and conversions, including understanding and performing basic measurement conversions and metric conversions. Word problems, applying mathematical concepts to solve real-world problems, often within a healthcare context. Key points to remember include that the exam focuses on practical math skills needed in healthcare. It is essential to review basic math concepts thoroughly, and practice with word problems is crucial for success.
Reading Comprehension:
This section consists of roughly 50 questions with a 60-minute time limit and evaluates the ability to understand written material, identify main ideas, draw inferences, and interpret information presented in passages. These skills are crucial for healthcare professionals who must accurately interpret patient charts, medical literature, and other essential documents. Click here to review.
Anatomy and Physiology:
This section consists of 25 questions in 30 minutes and evaluates understanding of human anatomy and physiological processes. This knowledge is crucial for healthcare professionals who must understand how the human body functions in both health and disease.
Vocabulary and General Knowledge:
This portion of the exam features about 50 questions in 50 minutes and assesses familiarity with vocabulary commonly used in both general and healthcare settings. A strong vocabulary is essential for effective communication with patients, colleagues, and other healthcare professionals.
Learning Style Assessment:
This section of the exam helps to provide information about the test takers preferred method of learning. This information is used by some schools to help better serve their students.
It is important to understand that the HESI A2 is not simply a test of memorization. Rather, it aims to assess critical thinking skills and the ability to apply knowledge in practical contexts. The importance of each section and the required passing scores can vary significantly between institutions. Therefore, it is essential for prospective students to carefully review the specific requirements of the programs they are applying to.
In conclusion, the HESI A2 is a significant component of the admissions process for many healthcare programs. It provides a standardized measure of academic readiness and helps admissions committees identify promising candidates. Thorough preparation is essential for success on this exam.
