How to Compare Careers
When you weigh two or more careers, compare the same four things for each:
- Time and cost to enter. Does the job need a certificate, a degree or an apprenticeship, and how long does that take?
- Licensing. Many healthcare, trade, teaching and legal jobs require a state license or national certification exam.
- Pay range. Look at the typical range, not just the top, and how pay grows with experience.
- 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.
