Nursing School Requirements at a Glance — Every Program Level
Nursing school requirements vary more dramatically across program levels than in most other healthcare education fields. A CNA program requires only a high school diploma and a background check. An MSN program requires a BSN, RN licensure, and graduate admissions components. Every program level in between has its own specific combination of academic, clinical, and administrative requirements. The table below maps the core requirements across all major nursing program levels — use it to identify exactly where you stand relative to your target program type.

Nursing School Science Prerequisites — What Courses You Need
Science prerequisites are the most important academic component of nursing school preparation. The courses required vary by program level and institution — the table below maps prerequisites across program types nationally. Always verify the specific prerequisites for each program you plan to apply to.
| Course | LPN | ADN | BSN | ABSN | Notes |
|---|---|---|---|---|---|
| Biology I and II (with lab) | Required at some | Yes — nearly universal | Yes — nearly universal | Yes — nearly universal | General or Cell Biology; lab required at most programs |
| General Chemistry I (with lab) | Rarely required | Required at most | Required at most | Yes — nearly universal | Inorganic Chemistry; foundation for pharmacology |
| General Chemistry II (with lab) | Not required | Required at some | Required at some | Required at many | Some programs accept Organic Chemistry instead |
| Organic Chemistry I (with lab) | Not required | Not required | Rarely required | Required at some | More common at research university ABSN programs |
| Biochemistry | Not required | Not required | Rarely required | Required at some | Increasingly required at competitive programs |
| Anatomy and Physiology I (with lab) | Required at most | Yes — nearly universal | Yes — nearly universal | Yes — nearly universal | Most scrutinized prerequisite at all program levels |
| Anatomy and Physiology II (with lab) | Required at some | Yes — nearly universal | Yes — nearly universal | Yes — nearly universal | Most scrutinized prerequisite at all program levels |
| Microbiology (with lab) | Required at most | Yes — nearly universal | Yes — nearly universal | Yes — nearly universal | Infection control foundation; lab required at most |
| Statistics or Biostatistics | Not required | Required at most | Required at most | Yes — nearly universal | Evidence-based practice foundation |
| Human Nutrition | Not required | Not required | Required at some | Required at some | Required at approximately 20% of programs |
| English Composition I and II | Not required | Required at most | Required at most | Fulfilled by bachelor's degree | Academic writing; most bachelor's degrees satisfy this |
| General Psychology | Not required | Required at most | Required at most | Required at most | Behavioral health foundation |
| Human Development or Lifespan Psychology | Not required | Required at some | Required at many | Required at many | Developmental across lifespan |
| Sociology or Medical Sociology | Not required | Required at some | Required at some | Required at some | Social determinants of health |
Prerequisite recency
Many nursing programs — particularly ABSN programs and competitive BSN programs — require that science prerequisites were completed within five to seven years of the application date. Anatomy and Physiology and Microbiology are the most commonly subject to recency requirements given the direct relevance of current knowledge to nursing practice. If your prerequisites were completed more than five years ago, contact each program on your list to verify whether retakes are required before you apply.
Grade requirements
Most nursing programs require a minimum grade of C in all prerequisite courses. Competitive BSN and ABSN programs prefer B or above in all science prerequisites. A C in Anatomy and Physiology or Microbiology is a specific flag for admissions committees because these courses directly underpin nursing pharmacology, pathophysiology, and clinical practice. If you received a C in a core science prerequisite, strongly consider retaking it before applying to competitive programs.
GPA Requirements for Nursing School — Minimum and Competitive Benchmarks
Nursing programs evaluate your GPA in multiple ways — cumulative GPA, science GPA, and in some cases prerequisite GPA calculated from specific required courses. Programs that use NursingCAS for applications recalculate your GPA using NursingCAS methodology, which may differ from your institutional transcript GPA. Use the Nursing School GPA Calculator to check your GPA before applying.
| Program Type | Minimum Cumulative GPA | Minimum Science GPA | Competitive Cumulative GPA | Competitive Science GPA | Notes |
|---|---|---|---|---|---|
| CNA | None | None | N/A | N/A | No GPA requirement |
| LPN | 2.0 – 2.5 | Not formally evaluated | 2.5 – 3.0 | 2.5 – 3.0 | Entrance exam score often more important than GPA |
| ADN (Community College) | 2.5 | 2.5 | 3.0 – 3.3 | 3.0 – 3.3 | Many programs rank applicants by GPA and TEAS score |
| BSN (Traditional) | 2.75 – 3.0 | 2.75 – 3.0 | 3.3 – 3.5 | 3.3 – 3.5 | Research university BSN programs expect 3.5+ |
| ABSN (Accelerated) | 3.0 | 3.0 | 3.3 – 3.5 | 3.3 – 3.5 | Recent science GPA scrutinized closely |
| RN-to-BSN Bridge | 2.5 | Not evaluated | 3.0 | Not evaluated | RN license more important than GPA |
| MSN | 3.0 | Not typically | 3.3 – 3.5 | Not typically | BSN GPA and RN experience more important |
| CRNA (DNP/DNAP) | 3.0 | 3.0 | 3.5 – 3.7 | 3.5 – 3.7 | Most competitive nursing program |
If your GPA is below the competitive range for your target programs, use the GPA Needed calculator in the Nursing School GPA Calculator to determine exactly how many additional credit hours of strong performance are required to reach your target GPA before applying. Timing your application to follow a semester of strong academic performance — rather than applying with the current GPA — is generally the better strategic choice for borderline applicants.
Nursing School Entrance Exams — TEAS, HESI, and NLN PAX
Most ADN, BSN, and ABSN programs require applicants to submit scores from a standardized nursing school entrance examination. These exams assess the academic readiness skills considered foundational for nursing education — reading comprehension, mathematics, science knowledge, and English language proficiency. A strong entrance exam score can strengthen a borderline GPA application, and a weak entrance exam score can undermine an otherwise competitive GPA. Treat entrance exam preparation with the same seriousness as prerequisite coursework.
The ATI TEAS — published by Assessment Technologies Institute — is the most widely required nursing school entrance examination nationally. The TEAS 7 (current version) consists of four sections: Reading (45 questions, 55 minutes), Mathematics (38 questions, 57 minutes), Science (50 questions, 60 minutes), and English and Language Usage (37 questions, 37 minutes). Total testing time is approximately 209 minutes. The Science section covers Biology, Chemistry, Anatomy and Physiology, and Life and Physical Sciences. A composite score of 70 percent or above is generally considered competitive. ATI publishes official TEAS preparation materials at atitesting.com.
The HESI A2 is the second most widely required nursing entrance exam. Programs select which HESI A2 sections to require — common sections include Reading Comprehension, Vocabulary and General Knowledge, Grammar, Mathematics, Biology, Chemistry, Anatomy and Physiology, and Physics. Each section is scored separately. A common threshold is 75 percent per section. Unlike the TEAS, the HESI A2 is modular — you take only the sections required by your target programs. Elsevier publishes official HESI A2 preparation materials.
The NLN PAX is used by a smaller number of nursing programs — primarily those affiliated with the National League for Nursing. The PAX consists of three sections: Verbal (80 questions), Mathematics (54 questions), and Science (80 questions). It is less commonly required than the TEAS or HESI A2. If your target programs list the NLN PAX as a requirement, verify the current version and preparation materials at nln.org.
| Exam | Sections | Total Time | Minimum Competitive Score | Preparation Materials | Used By |
|---|---|---|---|---|---|
| ATI TEAS 7 | Reading, Math, Science, English | ~209 minutes | 70%+ composite | ATI official materials (atitesting.com) | Most ADN, BSN, and ABSN programs |
| HESI A2 | Varies by program (Reading, Math, Science sections most common) | Varies | 75%+ per section | Elsevier official materials | Many ADN and BSN programs |
| NLN PAX | Verbal, Mathematics, Science | ~3 hours | Composite score varies | NLN official materials (nln.org) | NLN-affiliated programs |
Prepare for the nursing entrance exam specifically — do not assume that completing prerequisites is sufficient preparation. The ATI TEAS Science section tests Biology, Chemistry, and Anatomy and Physiology at a level that requires deliberate review of prerequisite content. ATI and Elsevier both publish official preparation books and online practice tests — use the official materials from the publisher of your exam rather than generic test prep resources. Most nursing school advisors recommend four to eight weeks of dedicated entrance exam preparation before sitting. If your first attempt score is below your target programs' minimums, most exams allow retakes after a waiting period — verify retake policies with each program.
Clinical Experience for Nursing School — What Is Required and What Helps
Unlike PA school and medical school, nursing programs do not universally require prior clinical experience for admission. However, clinical experience — particularly CNA certification and employment — is valued by competitive programs, strengthens applications, and confirms to both applicants and programs that the student has realistic expectations of nursing work. The following table maps clinical experience expectations across program levels.
| Program Type | Clinical Experience Required | Clinical Experience Valued | Most Valued Experience Types |
|---|---|---|---|
| CNA Program | Not required | Not applicable | N/A — entry-level credential |
| LPN Program | Not required | Moderately | Hospital volunteering, CNA work |
| ADN Program | Not required | Moderately | CNA certification, hospital volunteering, EMT |
| BSN Program | Not required | Moderately to highly | CNA certification, medical assistant, hospital volunteering |
| ABSN Program | Not required; strongly recommended | Highly | CNA, medical assistant, EMT, patient care technician |
| MSN Program | Not required | Not directly evaluated | Professional RN experience more relevant |
| CRNA Program | Yes — ICU RN experience mandatory | Extremely — type of ICU matters | Cardiac surgery ICU, surgical ICU, trauma ICU |
CNA certification and employment is the most accessible and universally recognized form of clinical experience for nursing school applicants. It demonstrates direct patient care competency, confirms commitment to nursing as a career, and provides the kind of specific patient interaction examples that strengthen personal statements and interview responses. For ABSN applicants in particular — who are often asked in interviews why they chose nursing after a different career — CNA experience provides concrete evidence that the career change decision was informed rather than impulsive.
When documenting clinical experience in nursing applications, be specific about clinical duties rather than describing your role in general terms. State the number of hours worked, the type of setting (hospital, nursing home, clinic), the patient populations cared for, and the specific clinical tasks performed. Admissions committees use experience descriptions to distinguish direct patient care from administrative or observational roles. Vague descriptions — "assisted nursing staff" — are less compelling than specific ones — "provided direct care as a CNA in a 36-bed medical-surgical unit including vital signs, bed baths, patient transfers, and specimen collection."
Nursing programs distinguish between healthcare experience (any work in a healthcare setting) and direct patient care experience (hands-on patient contact). Medical scribing, healthcare administration, hospital unit clerk work, pharmacy technician roles, and research assistant positions are healthcare experience but are generally not classified as direct patient care by nursing programs. CNAs, medical assistants performing clinical duties, EMTs, patient care technicians, and home health aides provide direct patient care. Both types of experience are relevant to nursing applications — but direct patient care is weighted more heavily.
Letters of Recommendation for Nursing School
Most BSN, ABSN, and MSN nursing programs require two to three letters of recommendation. The quality of letters matters more than the quantity — a specific, detailed letter from someone who has observed you in a clinical or academic setting is far more valuable than a generic character reference from an employer in an unrelated field.
| Letter Source | Value to Nursing Programs | Notes |
|---|---|---|
| Science professor — upper-division or lab course | Very High | Must speak specifically to academic capability and scientific aptitude |
| Clinical supervisor — CNA, EMT, or patient care role | Very High | Documents direct patient care experience and professional conduct |
| Registered Nurse who worked with you | High | Particularly relevant for ABSN programs |
| Healthcare provider (physician, PA, NP) | High | Strong if includes clinical observations of you working |
| Pre-nursing advisor with direct relationship | Moderate to High | Relevant if advisor has specific academic or professional observations |
| Academic advisor (no clinical relationship) | Moderate | Acceptable if other letters cover clinical and science dimensions |
| Employer from non-healthcare field | Low to Moderate | Relevant only if demonstrating exceptional transferable qualities |
| Personal character reference | Not recommended | Admissions committees discount letters without professional context |
Begin identifying letter writers at least six months before your application deadline — twelve months if you need to build relationships through clinical experience or coursework first. Give each writer adequate preparation time — a minimum of six weeks — along with your CV or resume, a draft of your personal statement, and specific notes about experiences you shared with them that you would like the letter to address. A well-prepared letter writer produces a more specific and compelling letter than one writing from distant memory. Follow up with a thank-you message after the letter is submitted and keep the letter writer informed of your admissions outcome.
The Nursing School Personal Statement — What Programs Expect
Length and format
Most nursing programs request personal statements of 500 to 1,000 words — or equivalent character limits for programs using NursingCAS or direct application systems. Some programs provide specific prompts — why nursing, why this program, describe a meaningful clinical experience — while others accept open-ended statements. Follow format instructions precisely. Exceeding stated word or character limits signals an inability to follow directions — a quality nursing programs actively screen for given the precision required in clinical documentation.
Open with a specific experience
Personal statements that open with a specific patient care moment, clinical observation, or pivotal personal experience are more compelling than statements that begin with general statements about wanting to help people or being drawn to healthcare since childhood. The opening paragraph sets the tone for the entire statement — admissions readers evaluate hundreds of statements and a specific, vivid opening distinguishes your application from generic submissions immediately.
Explain why nursing specifically
Nursing school admissions committees want to know why you chose nursing rather than medicine, physical therapy, social work, or another healthcare profession. The answer should come from something you observed or experienced — ideally during CNA work, hospital volunteering, or clinical observation — that specifically illustrated the distinctive value of nursing practice. Generic answers about nursing being a calling or about nurses spending more time with patients are common and unpersuasive. Specific answers grounded in observed clinical reality are rare and compelling.
Address weaknesses directly and briefly
If your application has a weakness — a low prerequisite grade, a difficult academic semester, a gap in education — address it directly in one to two sentences rather than leaving programs to draw their own conclusions. Briefly state what happened, what you did about it, and redirect to the present and future. A single C in Organic Chemistry addressed directly is far less damaging than an unexplained C that programs notice and wonder about.
Close with specificity about your goals
Close the personal statement with a specific description of your nursing specialty interests and long-term career goals — not a generic statement about wanting to make a difference. Specificity about your goals — pediatric nursing, emergency medicine, rural primary care, oncology — demonstrates that you have researched the profession and have a realistic vision of your career. It also creates coherence between your stated goals and the program you are applying to — particularly if you are applying to a program with a specific clinical focus or community emphasis.
