12 Professional Licenses Required by State and How to Start

State professional licenses control who can perform many important jobs and protect public health and safety. This guide walks through 12 common licenses you’ll meet when planning a career that requires state approval. For each entry, you’ll see a plain-language definition of the license, the typical steps to apply, common documentation boards ask for, and where to go next for official guidance. Requirements vary by state, but most boards ask for verified education, exam passage, identity checks, and continuing education for renewal. If you’re relocating or advising a student, note federal measures that help military families move licenses more easily, though each state still controls full practice rights. Use this list to identify the right state board to contact, gather transcripts and exam records early, and understand the order of steps—education, exam, application, then verification. Where specific rules differ, look up your state licensing board or the relevant professional association for the exact forms and fees. Keeping documents organized and starting early will save time when you submit an application. This article focuses on frequently regulated professions like health care, trades, teaching, and professional services, and it points you to the types of official sources that confirm final requirements.

1. Registered Nurse (RN)

A registered nurse license allows you to provide nursing care, administer medications, and work in hospitals, clinics, and home health settings. Most states require either an Associate Degree in Nursing (ADN) or a Bachelor of Science in Nursing (BSN) plus successful passage of the NCLEX-RN exam. States check school transcripts, clinical completion documentation, and often require a criminal background check and fingerprinting before issuing a license. If you trained in another state or country, many boards offer endorsement pathways where your original license is verified and your credentials reviewed; some boards ask for additional coursework or testing. Renewal cycles vary—some states require renewal every one to two years with documented continuing education units (CEUs). Military spouses should look for portability options; federal guidance has improved transfer procedures but state verification still applies. To start, contact your state board of nursing for an application checklist, NCLEX registration details, and exact fee schedules. If you’re a student, ask your nursing program for help submitting required paperwork. If you hold an out-of-state RN license, request a verification letter from the issuing state so you can speed endorsement in your new state.
