Everyone takes the same morning half ("AM" section). It has questions on math, physics, finance, ethics, and all the different types of engineering. A test taker can choose which section to take in the afternoon from among: Chemical engineering, environmental engineering, electrical/computer engineering, mechanical engineering, or general engineering (similar in content to the morning exam).
A test taker must get a score of 70 (approximately 50% correct) to pass.
The sections are scored independently. One can correctly answer all the questions in the morning section, but score only a 65 in the afternoon -- this would be a failure.
Those who pass the exam are considered to be engineers in training. They are partway done the certification process. After a 5 year apprenticeship, they qualify to take the Professional Engineer (PE) exam. Certification is awarded on successful completion of the PE exam.
