The Association of Professional Engineers of Ontario (PEO) Professional Practice Exam is divided into two parts:

  • Part A: Professional Practice and Ethics
  • Part B: Engineering Law and Professional Liability

Each part is divided into four equally-weighted primary questions worth 25 marks per question and 100 marks per part. An applicant has three hours to write both parts and the applicant must score 50 to pass each part of the examination.

The four primary questions of Part A: Professional Practice and Ethics may be classified as:

  1. The first primary question is broken into three to five secondary questions which tests knowledge of PEO and specific aspects of the Professional Engineers Act and Ontario Regulation 941 including the types of licences, Certificates of Authorization, the seal, the various committees, the Code of Ethics, the definition of misconduct, discipline, enforcement, etc.
  2. The remaining three primary questions test the knowledge and understanding of and the application the Code of Ethics and misconduct by presenting three case studies.

The four primary questions of Part B: Engineering Law and Professional Liability may be classified as:

  • The first primary question tests eight definitions (you must answer answer five) from engineering law and liabilities with respect to contracts (legally enforceable agreements) and tort (civil wrongs).
  • The remaining three primary questions test the knowledge and understand of and the application of engineering law by presenting three case studies.

Failing The Exam

If an applicant fails one part of the examination, that applicant is (apparently) allowed to write the failed part at a future sitting of the PPE; however, they will have only one-and-a-half hours to write that part of the examination. If an applicant fails both parts, that applicant must write the entire examination again at a future sitting.
