Certification or Licensing
Certification is voluntary and may be obtained through such organizations as the American Academy of Environmental Engineers and Scientists, the Institute of Professional Environmental Practice, and the Academy of Board Certified Environmental Professionals.
If your work as an engineer affects public health, safety, or property, you must register with the state. To obtain registration, you must have a degree from an accredited engineering program. Right before you get your degree (or soon after), you must pass an engineer-in-training (EIT) exam covering fundamentals of science and engineering. A few years after you've started your career, you also must pass an exam covering engineering practice. The exams are offered by the National Council of Examiners for Engineering and Surveying (http://www.ncees.org).
