Engineering Licensure

NCEES.   www.ncees.org   The National Council of Engineering Examination Services (NCEES) develops the engineering licensing exams. The members of NCEES are the state licensing and regulatory agencies. The website has much information and many links related to licensing and is a great place to start when researching the requirements to become licensed. The sample exams that can be purchased from NCEES are probably the nearest approximation to an actual exam available.

Board of Registration of Professional Engineers and Land Surveyors   www.mass.gov/orgs/board-of-registration-of-professional-engineers-and-land-surveyors   is the government agency that regulates the practice of engineering and surveying in the Commonwealth of Massachusetts.

This is the place to get the application forms and is where the completed forms are sent. Includes links to many licensing boards

Professional Publications Inc.   www.ppi2pass.com   Develops training materials for preparing for the licensing exams. Personal experience (2003) was that the PPI Reference Manual was probably the handiest and most useful reference I had during the PE exam, however, I think the NCEES sample tests are more realistic.
