Further education isn’t necessary for many biology careers, so the level of education you need will depend on what you want to do with your degree in biology.
If you plan on using your biology degree as a biologist for scientific research in a laboratory or field setting, for instance, you may not need a graduate degree, though a master’s or doctorate degree can help you earn a higher salary and progress more quickly in your chosen biological science field. If you’re more interested in using your biology degree in a career as a doctor, dentist or similar profession within in the medical field, you will most likely need to continue your education in medical school. And if you want to do research and teach biology at a university level, you will likely need a higher degree than your bachelor’s degree in biology.​​
