A continuing education credit, or contact hour, is the unit your certifying body uses to verify that you have completed approved post-licensure learning. One contact hour represents sixty minutes of educational engagement reviewed and validated by an accredited provider. Boards of nursing, midwifery, and pharmacology recognize these credits as evidence that you're keeping current with evolving evidence and practice standards.
Most APRN and midwife credentialing pathways require somewhere between 20 and 40 contact hours every two to three years, with a defined portion designated as pharmacology (commonly called RxCE). Specialty certifications layer additional requirements on top. Where you earn your credits matters: only credits issued by an accredited provider count toward those renewal totals, which is why the line at the bottom of your certificate is the line auditors actually read.
