Exam Format and Content

The subjects on each PTOE certification examination are selected to conform to the blueprint of subject domains and sub-domains listed below. The number of questions in each sub-domain area reflects the relative importance of that content area as determined by a comprehensive validation process involving judgments of several hundred practicing traffic operations engineers.

The exam is administered in two 3 hour sessions (9:00 a.m.-12:00 p.m. and 1:30 p.m.-4:30 p.m.) with a lunch break in between.

Questions within each category are designed to determine the candidate’s competence at different cognitive levels: 

  • Knowledge 
  • Analysis 
  • Comprehension 
  • Synthesis
  • Application 
  • Evaluation

At the knowledge level, candidates are expected to know terminology, measurement systems and basic engineering and physical relationships relevant to transportation. Candidates are expected to know basic relationships common to professional traffic operations practice; however, they will be provided with a variety of formulas and values related to the solution of examination problems, which a practicing traffic operations engineer would not normally be expected to commit to memory. 

At application and analysis levels, the candidate is required to determine the factors essential to the solution of a problem and select an appropriate solution—frequently using mathematical processes. It should be noted, however, that the examination is not intended to test the applicant’s mathematical skills. Examination questions may be presented in either metric or English units and answers may be required in either form. Tables of conversion factors will be provided. 

To assure objective scoring, the correct response to questions requiring synthesis and evaluation are based on documented sources drawn from references widely used in the profession.
