10. Total training time — CNA 4-12 weeks, LPN 12-18 months, RN 2-4 years
Before comparing paychecks, the biggest number is time. Certified Nursing Assistant programs typically run 4 to 12 weeks, LPN programs 12 to 18 months at community colleges, and RN pathways stretch from a 2-year Associate Degree in Nursing (ADN) to a 4-year Bachelor of Science in Nursing (BSN).
The gap matters because each month spent in school is a month without full nursing income. A CNA can be earning by month three. An LPN reaches licensure inside a year and a half in most states. An ADN-prepared RN takes roughly 24 months of full-time study, plus NCLEX-RN prep.
Data from the National Council of State Boards of Nursing (NCSBN) and state boards confirms these ranges. Accelerated ABSN programs compress BSNs into 12 to 16 months but require a prior bachelor's degree. Pick the timeline that matches your current situation before you look at salary.
