National Professional Practice Exam (NPPE)

A requirement for licensure, the NPPE is a 3-hour, closed-book, on-line exam on ethics, professional practice, engineering law and professional liability.

Important Update

Following a Council decision on March 20, 2020, PEO will be discontinuing the use of the PPE and using the National Professional Practice Exam instead. The PPE will not be offered to applicants who have not previously registered or taken the PPE.

Applicants who had registered for the March 28, 2020 sitting of the PPE, which was cancelled due to the COVID-19 restrictions, were offered the option of writing the NPPE remotely at its June sitting.

Those applicants who registered for March 28, 2020 sitting but decided not to take the NPPE in June and those applicants who have failed one or more parts of the PPE will be offered the opportunity to write the PPE at a special sitting that is now scheduled on October 19, 20, 21, 2020 and registration opens August 14, 2020 until August 28, 2020.  All eligible candidates are issued an email blast alerting to register to write for this one-time special exam if you choose to do so.  If you select not to this one-time special PPE sitting you will be required to re-write the NPPE exam for future sittings.

Please note that PEO will extend your time accordingly if the March 28, 2020 sitting was your final opportunity to complete the PPE.

Starting July 1, 2020 applicants can register for the NPPE on-line through the PEO portal.

What is the NPPE?

The National Professional Practice Examination (NPPE) is a 3-hour, closed-book, on-line exam on ethics, professional practice, engineering law and professional liability. Eligible applicants may write the NPPE at any time (within the time frame provided by PEO) as they acquire 48 months of engineering work experience required for licensure. To reduce the time to licensure, applicants are encouraged to write the NPPE early in the time frame provided by PEO.

The NPPE is held five times a year (February, April, June, September and November) in major centres across Canada. A remotely proctored is also available for those who are unable to write in an exam centre. Special accommodations can be made for those applicants with a demonstrated need. Contact the PEO Exam Centre for information about making special accommodation requests.

PEO's Exam Centre will send applicants a registration notice when they are eligible to write the exam.

The NPPE confirms knowledge of professionalism, law, and ethics. Twelve engineering and geoscience self-regulatory organizations in Canada currently use the NPPE. The NPPE follows all relevant standards detailed in the Standards for Educational and Psychological Testing to ensure that the exam program is valid, reliable, and fair (psychometrically defensible).

For more information about this examination please see the Candidate Guide in the NPPE Document section below.

Writing the National Professional Practice Exam

The exam has 120 multiple-choice questions based on 6 subject areas. Ten of these questions are PEO-specific and deal with the Professional Engineers Act, Regulations 941 and 260/08, and Ontario focused practice issues. The remainder are based on information in the textbooks and other resources. You have 3 hours to complete the examination. Although the NPPE contains specialized vocabulary and terms, the exam is not used as a test of English language proficiency and is regularly verified (using standard readability measures) to function at a readability level of approximately grade 10.

Three textbooks and several free resources are recommended as study materials to prepare for the NPPE.

Several practice tests are available to help you prepare for the NPPE. Practice test questions are ones used on previous NPPE exams. The practice test gives you detailed feedback showing you your areas of strength and weakness in terms of learning. To best use the practice tests, we recommend that you take one early in your studying process and then later to determine which areas you still need to focus on.

The practice test site also sells an NPPE preparation package, which includes the two textbooks and access to a 100-question practice test at a discounted price.

NPPE in Three Steps

Step #1 – Complete a PEO licence application. Once PEO receives your completed licence application with the appropriate payment, you will be issued a PEO file number.

Step #2 – Wait. Two months prior to the date of the next available NPPE, PEO's Exam Centre will send all eligible NPPE candidates a registration email with information on how to register to write the exam.

Step #3 – Eligible NPPE candidates who wish to write the exam at the next available sitting are required to register and submit payment in accordance with the instructions provided in the registration email. If you do not receive your registration email approximately two months prior to the sitting in question, contact the Exam Centre.


Graduates of a Canadian Engineering Accreditation Board Program

Once you submit a licence application to PEO and obtain a PEO file number, you will be informed of your time frame to write the NPPE.

International Engineering Graduates

International engineering graduate applicants who have submitted a licence application and have been assigned a PEO file number may be required to write and pass a technical exam program before being eligible to write the NPPE. This requirement is determined on a case-by-case basis.

Examination Sittings, Locations and Fees

The NPPE is offered five times per year. Each session for that month offers the exam six times: one morning and one afternoon slot over three days.
