Explore Careers by Goal

Your best career depends on what you want from it: higher pay, more stability, a faster start or a fresh direction mid-career. These lists rank occupations by those goals and point you to the training each one requires.

Healthcare Careers

Healthcare training paths vary more than in any other field. Technician and assistant roles can start with a certificate or associate degree. Advanced practice roles need a graduate degree. Physician specialties take a medical degree plus residency.

Start in Under Two Years

Advanced and Allied Health

Physicians and Specialists

Law Enforcement, Legal and Public Safety Careers

Most entry-level public safety jobs start with academy training rather than a degree. Specialized units, federal agencies and forensic roles add college coursework or years of experience. Judges and lawyers need a law degree and bar admission.

Teaching and Education Careers

Teacher certification is set by each state, so the steps depend on where you plan to teach. Many states now offer alternative routes for career changers who already hold a bachelor's degree. Start with the general guides, then check your state's requirements.

Skilled Trades Careers

Trade careers usually pair a certificate program or apprenticeship with a state license. You earn while you train, and you can reach full pay sooner than with a four-year degree.

Science and Animal Careers

Research science careers typically need a bachelor's degree to start and a graduate degree to lead projects. Animal careers range from certificate-level roles to the Doctor of Veterinary Medicine.

How to Compare Careers

When you weigh two or more careers, compare the same four things for each:

  1. Time and cost to enter. Does the job need a certificate, a degree or an apprenticeship, and how long does that take?
  2. Licensing. Many healthcare, trade, teaching and legal jobs require a state license or national certification exam.
  3. Pay range. Look at the typical range, not just the top, and how pay grows with experience.
  4. Job outlook. Projected growth tells you how easy it will be to find openings.

Every Learn.org career guide covers these in the same order, so you can line options up quickly. For official national figures, see the U.S. Bureau of Labor Statistics' Occupational Outlook Handbook.
