The PE exam is worth a maximum score of 80 points (eight problems at ten points each). By a scoring plan for essay problems, partial credit is given that results in an even-numbered score between 0 and 10 points. The problems and scoring are designed with priority given to defining what type of response will receive six points. The scoring plan follows this point format: 10 points (exceptional competence not necessarily perfect solution); 8 points (more than minimum but less than exceptional competence); 6 points (minimum competence incomplete solution); 4 points (more than rudimentary knowledge but insufficient to demonstrate competence); 2 points (errors in answers due to lack of understanding); 0 points (no indication of any knowledge of the problem or how to solve it).

Each of the ten questions in a multiple-choice problem is worth one point, with no penalty for wrong answers.

The NCEES recommends a minimum passing score of 48 points, or an average of six points per problem. Problems yielding a score of less than six may be compensated for by higher scores on other problems. Ultimately, the authority for deciding on licensure of a particular candidate rests with the individual registration board. The NCEES can only recommend a passing score based upon what it considers to be minimum competency.
