RN Diploma Vs. ADN Vs. BSN Degree: What's The Difference?

Key Takeaways

• The three RN entry paths are the RN diploma, the ADN, and the BSN. Employers prefer the BSN, and diplomas are now rare.
• BSN nurses earn about $18,000 more per year than ADN nurses on average.
• ADNs are faster and cheaper; BSNs offer deeper knowledge and stronger long-term growth.

You can become a registered nurse through an associate degree in nursing (ADN) or an RN diploma, both shorter than a bachelor of science in nursing (BSN). Most employers prefer to hire RNs with a BSN (28% require one and 72% strongly prefer one, per the American Association of Colleges of Nursing's 2024 employer data), and RN diplomas are fading out, with only a few programs left. Here is how the three paths compare.

What Is an RN Diploma or Certificate?

• Credits Required: 50 credits
• Average Program Length: 1-2 years
• Average Salary: $74,000 (Payscale, January 2026)

Diploma programs were the original nurse training option in the U.S. These hospital-based programs focus on clinical training over classroom coursework. Graduates can sit for the NCLEX-RN but do not earn a degree, and their pass rates tend to run lower than ADN or BSN graduates.

These programs are becoming less common. Research links nursing degrees, particularly the BSN, to better patient outcomes, and the National Academy of Medicine recommends nurses hold a BSN, which has pushed many employers to require one.

Admission requirements often include:

• A high school diploma or GED certificate
• English language proficiency, if applicable
• Math and science high school courses
• College prerequisites including statistics, anatomy and physiology, and chemistry
• A 2.0-3.0 GPA or higher
• An application and fee

What Is an Associate Degree in Nursing?

• Credits Required: 60-75 credits
• Average Program Length: 2 years
• Average Salary: $81,000 (Payscale, January 2026)

The main difference between a diploma and an ADN is the general education coursework an ADN adds. Along with clinical training, ADN students take classes like psychology, obstetric nursing, and pharmacology, then qualify for the NCLEX-RN. ADN programs are generally shorter and cheaper than BSN programs, though it varies by school and enrollment status. ADN credits can later count toward a BSN or MSN.

Admission requirements often include:

• A high school diploma or GED certificate
• English language proficiency, if applicable
• Math and science high school courses
• A 3.0 GPA or higher
• An application and fee

What Is a Bachelor of Science in Nursing?

• Credits Required: 120 credits
• Average Program Length: 4 years
• Average Salary: $99,000 (Payscale, January 2026)

A BSN opens more advancement opportunities than an ADN. BSN students complete the same classroom and clinical foundation, plus advanced courses in leadership, research, and public health. Graduates qualify for the NCLEX-RN and can apply their credits toward an MSN. BSN programs run longer and cost more, but they tend to bring higher pay, more job stability, and stronger advancement.

Admission requirements often include:

• A high school diploma or GED certificate
• English language proficiency, if applicable
• Math and science high school courses
• A 3.0 GPA or higher
• An application and fee

Advantages of Earning an ADN or a BSN

Advantages of Earning an ADN

• Lower cost and less student debt
• Shorter than a four-year degree
• Widely available at community and junior colleges
• Credits transfer toward a BSN bridge program
• Start earning an RN salary sooner

Advantages of Earning a BSN

• Deeper training and broader nursing knowledge
• Employers prefer BSN-prepared nurses
• Access to roles beyond entry level
• Higher first-time NCLEX-RN pass rate
• Higher salary potential

Salary Potential for RNs With ADN vs. BSN Degrees

RN salaries average roughly $74,000 to $99,000 depending on education level, and BSN-prepared RNs earn about $18,000 more per year than ADN holders. Location, specialty, and experience all move that number.

Frequently Asked Questions

What is the difference between an RN, an ADN, and a BSN? An ADN and a BSN are college degrees; an RN is the license. You need an ADN or BSN to sit for the NCLEX-RN and become a licensed RN.

Should I get an ADN or a BSN? It depends on your goals. An ADN gets you to RN faster and cheaper, while a BSN supports higher pay, more roles, and graduate study. Note that "RN" is sometimes used in place of "ADN," as in RN-to-BSN bridge programs.

Is a BSN better than an ADN for advancement? Generally, yes. A BSN-prepared nurse has more advancement options and can move into an MSN or Doctor of Nursing Practice (DNP) program faster. Employer demand reflects this: 28% of employers require a BSN and 72% strongly prefer one (AACN, 2024).

Is a two-year RN "higher" than a four-year BSN? No. A BSN can lead to higher pay and roles like charge nurse, but salary and opportunity also depend on location, experience, and leadership skills.

How much more do BSN nurses earn? BSN-prepared RNs earn roughly $18,000 more per year than ADN holders on average (Payscale). The national median for all RNs was $93,600 in May 2024 (Bureau of Labor Statistics).
