ADN Program Requirements: Step by Step Guide to Apply
This ADN program requirements step by step guide breaks down eligibility, prerequisites, TEAS scores, and application materials so you can avoid delays and start nursing school on time.
By Mia Roberts
You have decided to become a registered nurse, and the fastest practical route is the Associate Degree in Nursing, or ADN. Before you can sit in a nursing classroom or step onto a clinical floor, you have to clear a specific set of admission hurdles. Miss one deadline or overlook a single prerequisite, and your application may be pushed to the next cohort, which can cost you an entire semester. This ADN program requirements step by step guide walks you through each stage in order, from confirming your high school credentials to signing your first hospital orientation paperwork. You will also learn how to compare programs, manage costs, and avoid the most common mistakes that delay admission.
Step 1: Confirm You Meet the Basic Eligibility Requirements
Every accredited ADN program starts with a baseline eligibility screen. Before you request transcripts or study for the TEAS, verify that you meet the non-negotiable criteria. Most programs require a high school diploma or a GED, and some will accept a certificate of completion from a state-approved home school program. If you attended college previously, you will usually need a minimum cumulative GPA, often between 2.5 and 3.0 on a 4.0 scale. A few competitive programs set the bar at 3.2 or higher.
Age requirements vary. Many community colleges admit students at 18, while some hospital-based diploma programs require applicants to be at least 18 at the start of clinical rotations. You will also need to demonstrate English proficiency if your prior education was in another language, usually through TOEFL or IELTS scores. Finally, check whether the program requires a certified nursing assistant (CNA) credential before admission. Some ADN tracks build CNA training into the first semester, while others expect you to arrive with that certification already in hand.
Physical and immunization requirements are not admission criteria per se, but they are prerequisites for clinical placement, and you cannot complete the program without them. Expect to provide proof of current immunizations, a negative tuberculosis test, a physical exam, and sometimes a drug screen and background check. Start gathering these documents early, because some titers and vaccination series take weeks or months to complete.
Step 2: Complete Prerequisite Coursework
Prerequisites are the single biggest reason applicants miss their target start date. ADN programs typically require between 15 and 30 credits of general education and science courses before you enter the nursing core. The exact list varies by state and institution, but common requirements include the following.
- Anatomy and Physiology I and II with labs
- Microbiology with lab
- English Composition I and II
- College Algebra or Statistics
- Introduction to Psychology and Human Growth and Development
- Nutrition or a similar health science elective
Science courses are the gatekeepers. Many programs require a grade of C or better in every prerequisite, and some demand a B or higher in anatomy and physiology. You may be allowed to repeat a course once, but repeated withdrawals or failing grades can disqualify you from competitive cohorts. Pay attention to expiration dates as well. Several programs will not accept science prerequisites older than five years, so if you took biology a decade ago, plan to retake it.
Where you take prerequisites matters. Community college courses are usually the most affordable option, and many ADN programs give preference to applicants who complete prerequisites within their own institution or district. Online science labs are accepted by some schools but rejected by others, so confirm before you enroll. If you are weighing a bridge pathway, our guide on LPN to ADN programs explains how prior nursing coursework can shorten the prerequisite list.
Step 3: Take and Score Well on the TEAS or HESI
Almost every ADN program requires an entrance exam. The two most common are the Test of Essential Academic Skills (TEAS) and the Health Education Systems Incorporated (HESI) A2 exam. Both cover reading, math, science, and English language usage, but the scoring scales and content emphasis differ. TEAS scores range from 0 to 100, and many programs set a minimum composite score between 60 and 70, with competitive applicants often scoring above 75. HESI A2 scores are reported as percentages per section, and programs may require a minimum in each subsection rather than just an overall average.
You can usually retake the exam, but most schools limit you to two or three attempts within a 12-month period, and some require a waiting period between attempts. Prepare with a structured study plan. Review basic algebra, reading comprehension strategies, and foundational biology and chemistry. Many students underestimate the reading section, which uses nursing-style passages and asks you to draw inferences rather than simply recall facts. Take at least one full-length practice test under timed conditions so you know how the pacing feels.
Schedule your exam early enough that your scores arrive before the application deadline. Score reporting can take several business days, and rushing the process adds unnecessary stress. If your first score is below the threshold, use the waiting period to strengthen weak areas rather than immediately rebooking.
Step 4: Prepare Your Application Materials
Once your prerequisites and entrance exam are in progress or complete, assemble the rest of your application. Most ADN programs use an online portal, and some participate in a centralized nursing application service for their state. You will typically need official transcripts from every college you have attended, even if you only took one course. Transcripts must be sent directly from the institution, not forwarded by you, so request them several weeks in advance.
Expect to submit the following items.
- Completed online application and application fee
- Official high school or GED transcript
- Official college transcripts from all previous institutions
- Entrance exam scores sent electronically by the testing company
- Two or three professional or academic references
- A personal statement or essay explaining your interest in nursing
- Current resume or CV, especially if you have healthcare experience
Letters of recommendation carry more weight when they come from supervisors, science instructors, or healthcare professionals who can speak to your work ethic and ability to handle stress. Give your recommenders at least three weeks of notice and provide them with a summary of your goals and accomplishments. For the personal statement, avoid generic statements about wanting to help people. Instead, describe a specific experience that shaped your decision and connect it to the demands of nursing practice.
If you are also considering a four-year route, you can compare timelines and costs through resources such as DegreesOnline.Education, which reviews accredited online degree programs for working adults. The key is to choose the path that matches your timeline, budget, and learning style, then commit fully to that application cycle.
Step 5: Submit Before the Deadline and Track Your Status
Deadlines for ADN programs are strict, and late materials are usually discarded without review. Many community college programs use a priority deadline in early spring for a fall start, with a secondary deadline in early fall for a spring start. Some competitive programs accept applications only once per year. Mark every deadline on your calendar, including the date by which transcripts and test scores must arrive, not just the date you click submit.
After submitting, monitor your application portal weekly. If a document is missing, you may have only a few days to resolve it. Contact the admissions office by email so you have a written record of the conversation. If you are placed on a waitlist, ask whether the program ranks waitlisted applicants and how many typically receive offers. Some students improve their standing by retaking the TEAS, completing additional prerequisites, or earning a CNA certification while they wait.
Step 6: Complete Post-Admission Requirements
Acceptance into an ADN program is not the final step. Before your first clinical rotation, you must clear a series of compliance requirements. These often include a criminal background check, a drug screen, a physical examination, a current CPR certification for healthcare providers, and proof of health insurance. Some clinical sites also require additional facility-specific orientation modules or a flu vaccination during the appropriate season.
You will also need to attend a mandatory program orientation, register for your first-semester courses, and purchase uniforms, stethoscopes, and other clinical supplies. Financial aid disbursement may not arrive before tuition is due, so plan for a payment arrangement or a short-term payment plan if needed. Meet with a financial aid advisor to confirm that your FAFSA is processed and that you understand the difference between grants, loans, and work-study awards.
How to Choose the Right ADN Program for Your Goals
Not all ADN programs are equal, even when they share accreditation. The right program for you depends on location, cost, scheduling flexibility, and NCLEX pass rates. Start by checking accreditation. A program accredited by the Accreditation Commission for Education in Nursing (ACEN) or the Commission on Collegiate Nursing Education (CCNE) meets rigorous standards and ensures your credits transfer more easily if you later pursue a BSN.
Next, examine NCLEX-RN first-time pass rates. Programs must publish these figures, and a rate consistently above 80 percent is a strong signal. Ask about clinical placement sites and the ratio of students to clinical instructors. Smaller groups often mean more hands-on time and better supervision. Finally, calculate the total cost, including tuition, fees, books, uniforms, testing fees, and transportation to clinical sites. Community college ADN programs are typically the most affordable, but private programs may offer faster start dates and more flexible schedules.
If you are a working adult, ask whether the program offers evening or weekend cohorts, part-time options, or online didactic coursework with in-person labs. These formats can make the difference between finishing and dropping out. Visit the campus if possible, talk to current students, and review the program's completion and job placement data. The more informed you are before you apply, the better your chances of succeeding once you are admitted.
Earning an ADN is a demanding but achievable goal when you approach the requirements in the right order. Confirm your eligibility, finish your prerequisites with strong grades, prepare for the entrance exam, and submit a complete application well before the deadline. Then stay on top of post-admission compliance tasks so nothing delays your start. With careful planning and a clear timeline, you can move from applicant to nursing student and begin the clinical training that leads to RN licensure.
