Choosing References and Validators for Your P.Eng Application

Your competency narratives are your own account of your experience. References and validators are the independent confirmation that the account is true. No regulator licenses an engineer on self-report alone; the experience you claim must be vouched for by people who saw you do the work and can speak to your competence and character. For many candidates, lining up the right people is the part of the application that is most outside their direct control, which is exactly why it deserves early attention.

It helps to separate two roles that the terminology sometimes blurs. A "validator" (or experience verifier) confirms the specific work and competencies described in your narratives, usually because they supervised or directly observed that work. A "reference" or "referee" speaks more broadly to your overall competence, professionalism, and good character. The exact terms and structure vary by province, but the underlying idea is consistent: someone credible, who is not you, has to stand behind your claims.

In most jurisdictions, the people who validate your engineering experience must themselves be licensed professional engineers, and usually it should be the P.Eng who supervised the relevant work, your direct supervisor, project lead, or a senior engineer who reviewed and took responsibility for what you did. The reason is straightforward: a validator is attesting that engineering work happened, was done competently, and was of professional substance, and a licensed engineer who oversaw it is the person positioned to say so credibly.

There is nuance worth knowing. Some regulators allow a limited number of validators or references who are not P.Eng, for example a non-licensed supervisor who can speak to your work or character, provided the bulk of your validation comes from licensed engineers. Engineers licensed in other provinces, or in some cases other recognized jurisdictions, may be acceptable. Family members and close personal friends are generally not acceptable as references. Because the specific rules on who counts, and how many of each type, differ by regulator, confirm your own regulator's requirements early rather than assuming.

The number varies by province, but the structure is similar everywhere: you need enough validators to cover the span of experience you are claiming, plus a set of references attesting to your overall suitability. A single validator rarely covers four years across multiple roles, so most candidates draw on several people, each confirming the period and projects they actually witnessed. If you worked at two firms over your qualifying experience, you will typically need validation from each.

The practical implication is to map your experience to people before you start the application. Lay out your qualifying period, identify which P.Eng can speak to each chunk of it, and check that every project you intend to use in a narrative has a credible validator attached. Gaps in that map, a period nobody licensed can vouch for, a key project whose supervisor has retired or become unreachable, are problems to surface early, while you can still solve them, not at submission time.

Validators are not writing you a glowing letter of recommendation. They are confirming facts: that you worked in the period and roles you state, that the engineering work in your narratives genuinely occurred and that your described contribution is accurate, that the work was of appropriate engineering substance, and that you demonstrated the competencies you claim. In practice this often means the validator reviews your competency narratives and confirms, competency by competency or period by period, that your account matches what they observed. They may also comment on your judgment, reliability, and professional conduct.

References speaking to character attest to your integrity, professionalism, and fitness to hold a licence in the public interest. Because validators confirm specific claims, the accuracy of your narratives matters enormously: a validator asked to endorse an exaggerated or imprecise account is being put in an awkward position, and a careful one will correct or decline it. Write narratives your validators can confirm without hesitation, and the validation step becomes a formality rather than a negotiation.

Ask early, ask directly, and make it easy. Approach your prospective validators well before the deadline, ideally months ahead, and certainly before you have written narratives that depend on them. A good ask is specific: explain that you are applying for your P.Eng, that you would like them to validate the experience you did under their supervision, roughly what that will involve (reviewing and confirming a set of narratives, completing the regulator's verification form), and the timeframe you are working toward.

Make the task small for them. When the time comes, give each validator clean, accurate narratives covering only the work they witnessed, a clear note of what you are asking them to confirm, and the regulator's form or link. The less reconstruction and chasing you require of a busy senior engineer, the faster and more willingly they respond. It is also wise to keep your prospective validators warm over the years: staying in touch with former supervisors, rather than resurfacing cold after a job change, is what makes the eventual ask comfortable for both sides.

The most damaging pitfall is leaving references to the end and discovering that a key validator has retired, moved, left the profession, or simply gone quiet. A validator you cannot reach is a hole in your application that no amount of narrative quality can fill. The second is choosing the wrong people: someone too junior to credibly attest to engineering substance, someone who did not actually oversee the work you are claiming, or someone whose relationship to you (family, close friend) disqualifies them.

Other recurring problems: validators who are slow to respond and stall the whole application; narratives that overstate your role, putting a conscientious validator in the position of having to correct them; and a mismatch between the experience you claim and what any single validator can actually confirm. Almost all of these are avoidable with early planning. Identify your validators before you write, keep them informed, give them accurate material, and treat their time as the scarce resource it is. The candidates whose applications move smoothly are almost always the ones who solved the references problem first, not last.
