A PEO validator is a professional who reviews and independently rates the engineering experience an applicant submits through the Competency-Based Assessment. The validator checks whether the assigned work examples are accurate, whether the applicant demonstrated the stated competency and whether the described responsibility and outcome match what the validator knows about the work.
Applicants must choose validators who meet PEO’s eligibility requirements and know the relevant work well enough to assess it objectively. The number needed depends on how the applicant’s examples are distributed across supervisors, employers, countries and work periods. This article explains who qualifies, how to assign each competency and what validators review before PEO completes its assessment.
Key highlights
- Each PEO CBA work example must be assigned to one validator; multiple validators are allowed, but two cannot be assigned to the same competency.
- For work performed in Canada, the validator must have been licensed as a P.Eng. in Canada when the work occurred.
- For experience outside Canada, the validator should be a senior engineering practitioner licensed in the relevant jurisdiction and able to prove their qualifications if requested.
- The best validator has direct, firsthand knowledge of the work, although PEO may accept another sufficiently informed professional and decides acceptability.
- Applicants and validators rate independently, while PEO assessors make the final assessment and licensure recommendation.
Quick Answer: Who Can Be a PEO Validator and How Many Do You Need?
A PEO validator is a person selected to validate and rate an applicant’s engineering work experience. For Canadian work, the validator must have held a Canadian P.Eng. licence when that work was carried out. For international work, the current PEO guide calls for a senior engineering practitioner who is licensed in the jurisdiction and can provide proof of engineering qualifications if requested. In every case, the person needs enough knowledge of the applicant’s skills and the assigned example to assess it objectively.
PEO does not set a universal requirement for two validators. It requires one validator for each work example. An applicant may use one person across the application when that person is eligible and genuinely knows all the assigned evidence, or several validators when experience spans different supervisors, organizations, countries or responsibility levels. Only one validator can be assigned to a particular competency.
What Does a Validator Do in the PEO CBA?
The validator’s role is broader than confirming employment. They assess the examples assigned to them and provide an independent professional view of the competence demonstrated. Under the current PEO CBA Applicant Guide, a validator is expected to:
- Confirm that the competency has been met.
- Verify technical ability, understanding and application of engineering principles and theories.
- Confirm the location, breadth and depth of the experience.
- Score each assigned competency using the rating scale.
- Provide feedback on the work examples being rated.
- Share engineering qualifications if PEO requests them.
The validator should not simply approve the applicant’s self-rating. Applicant and validator ratings are completed independently. PEO assessors then review the submission and validator feedback, apply their own ratings and make the final recommendation on licensure.
Validator, Supervisor, Referee and Assessor: Different Roles
These terms describe different functions, even when one person could qualify for more than one role.
| Role | Relationship to the applicant | Function in or around the application |
|---|---|---|
| Validator | Knows the claimed work or the applicant’s demonstrated skill level sufficiently | Validates and independently rates assigned competency evidence |
| Supervisor or manager | Directed, reviewed or held responsibility for the applicant’s work | Often a strong validator candidate when the eligibility rules are met |
| Referee or reference | Supports a separate character, experience or application requirement defined by PEO | Should not be assumed to replace a CBA validator |
| PEO assessor | Acts within PEO’s qualification assessment process | Reviews the application and validator input, assigns the controlling assessment ratings and supports the final decision |
A senior title alone does not make someone a suitable validator. A department director who barely knew the applicant’s contribution may be less useful than a project engineer who reviewed the actual decisions and results.
Who Qualifies for Canadian and International Experience?
Canadian Engineering Experience
For work performed in Canada, Canadian validator eligibility depends on the person’s licence status during the relevant work period. The validator must have been licensed as a P.Eng. in Canada when the work was carried out. Check the regulator, licence status and dates instead of relying only on a current title or post-nominal letters.
The licence must already have been in place during the project. A person who obtained a P.Eng. afterward may know the work well, but the later licence does not satisfy the requirement for validating that earlier Canadian experience.
International Engineering Experience
For experience obtained outside Canada, the validator should be a senior engineering practitioner, licensed in the jurisdiction where applicable, and able to provide academic, engineering and professional credentials if PEO requests proof. Record the country, registration body, designation, licence or registration period, relationship to the applicant and projects the person knows.
International experience does not become weaker merely because the validator is outside Canada. The evidence must still be clear, and the validator must be able to assess the applicant’s engineering knowledge, responsibility and results credibly.
Knowledge of the Applicant’s Work
Credentials and knowledge work together. PEO describes a direct supervisor from the same workplace as the ideal validator because that person is usually closest to the work. Managers, mentors, clients or colleagues may also be considered. A person who did not work with the applicant during the example may still be suitable if they know the applicant’s skill level well enough to validate and rate the competence objectively.
The closer the relationship to the actual work, the stronger the verification. PEO assessors decide whether a proposed validator is acceptable, so applicants should document both eligibility and the basis of the person’s knowledge.
Who Is Usually a Weak or Unsuitable Choice?
- A credentialed engineer who did not observe the work and does not know the applicant’s demonstrated skill level.
- A senior executive who knows the project name but cannot distinguish the applicant’s contribution.
- A colleague chosen only because they currently hold a P.Eng.
- A person unwilling to give an independent rating or correct inaccurate claims.
- A consultant or writer who helped prepare the application but never supervised or observed the engineering work.
- A person whose licence or professional standing does not satisfy the rule for the work period being validated.
- The applicant themself.
PEO assessors consider family members case by case rather than treating them as automatically acceptable or prohibited. Because independence may be questioned, an eligible non-family validator with strong knowledge of the work is generally the clearer choice when one is available.
How Many PEO Validators Should You Use?
The correct number is the smallest set of eligible people who can credibly cover all 34 competency examples. One validator may be sufficient for an applicant who worked under the same eligible supervisor across a broad range of responsibilities. More are usually appropriate when evidence comes from different employers, work periods, countries, supervisors or specialist projects.
Use another validator when the existing person would have to guess about the work. Do not add contacts merely to make the application appear stronger. Every additional validator creates another communication path and another opportunity for inconsistent dates, roles or project descriptions.
| Experience pattern | Likely validator approach |
|---|---|
| One employer and one eligible supervisor with broad direct knowledge | One validator may cover many or all competencies |
| Several projects under different accountable engineers | Assign each example to the person best able to verify it |
| Multiple employers or career stages | Use validators aligned with the relevant employment periods |
| Canadian and international work | Apply the appropriate eligibility rule to each example |
| Technical and management evidence observed by different people | Split assignments according to actual knowledge |
Build a Competency-to-Validator Map Before Submission
Map the evidence before entering final assignments in the portal. This exposes gaps while there is still time to contact former supervisors, revise an example or choose a better-informed person.
| Competency or example | Employer and period | Project | Proposed validator | Basis of knowledge | Eligibility status |
|---|---|---|---|---|---|
| Example entry | Organization and dates | Project A | Supervisor A | Reviewed my analysis and approved the recommendation | Confirmed or pending |
- List all competency examples and the work period behind each one.
- Identify who supervised, reviewed or directly knew each example.
- Check the person’s licence or professional standing for that period.
- Assign the competency to the best-informed eligible person.
- Mark examples for which no strong validator exists.
- Confirm that each proposed validator is willing, reachable and able to respond.
- Compare the assignment with the experience record, dates, employer and role descriptions.
The map should follow evidence, not convenience. If one person knows only the technical calculation and another observed the stakeholder decision, assign each competency according to the behaviour being demonstrated.

What Will a PEO Validator Review?
Accuracy and Personal Contribution
The validator checks whether the project, location, period, role, actions and outcomes reflect the work as they know it. They should be able to separate the applicant’s contribution from team activity and identify where responsibility, review or approval belonged to someone else.
Engineering Competence
The example should demonstrate the selected behaviour, not merely describe a duty. The validator considers whether the applicant’s analysis, judgment, standards, constraints, decisions and results match the competence claimed and the responsibility observed.
Independent Rating and Feedback
The validator scores the assigned competency independently using the PEO scale and provides feedback on the work example. A difference from the applicant’s self-rating is not a process failure. It is independent evidence that PEO assessors consider alongside the application.
What a Validator Is Not Responsible For
A validator is not expected to write the applicant’s examples, invent missing evidence, edit every sentence or guarantee licensure. They should not validate competencies they do not know, adopt a rating supplied by the applicant or hide a factual disagreement. They also do not make PEO’s final decision.
The applicant remains responsible for accurate, authentic and appropriately confidential content. Professional writing or review support can improve organization, but it cannot replace a genuine validator relationship.
When and How to Contact a Proposed Validator
Contact validators before the application reaches the notification stage. Once PEO notifies validators, the applicant can no longer change the experience information. Early contact creates time to confirm credentials, reconcile dates, answer questions and correct factual problems.
A clear request should include:
- The shared workplace, project and period that connect the applicant and validator.
- A direct request to act as a PEO CBA validator.
- The examples or competencies proposed for assignment.
- A concise explanation of independent validation and rating.
- The expected timing and current contact information.
- Access to the official instructions, without suggesting a desired score.
Keep the request professional and easy to decline. A reluctant person who lacks time or confidence in the evidence is not a secure validation plan.
Prepare the Validator Without Coaching the Rating
Preparation means giving the person enough accurate context to complete an independent assessment. Share the work examples assigned to them, the corresponding employment period and any safe supporting context needed to recognize the project. Ask them to identify factual errors, unclear personal contributions or outcomes they cannot confirm.
Do not send a requested rating, provide language for the validator to copy or pressure them to agree. If confidential information is involved, replace protected names or values while keeping the engineering reasoning understandable. The objective is a consistent factual record, not a rehearsed answer.
What If a Validator Disagrees With the Example or Rating?
Start with the reason for the difference. The validator may remember the scope differently, believe the applicant had less authority, dispute an outcome or interpret the rating level more conservatively. Correct factual inaccuracies and make the limits of responsibility explicit.
If the person genuinely lacks knowledge of that example, consider whether another eligible validator has a stronger basis to assess it. Do not replace a credible validator merely to seek a higher score. PEO expects independent ratings, and its assessors make the controlling judgment.
Difficult Validator Scenarios and Practical Responses
| Scenario | Practical response |
|---|---|
| Former supervisor changed employers | Locate their current professional contact details and confirm the exact work period they remember |
| Former employer no longer exists | Identify an eligible former supervisor, manager or client with sufficient knowledge; seek PEO clarification if uncertain |
| Canadian supervisor was not a P.Eng. at the time | Identify another person who met the Canadian licensing rule and knew the work sufficiently |
| Experience was gained outside Canada | Record the validator’s jurisdiction, licence, seniority, credentials and relationship to the work |
| One person knows only part of a project | Assign only competencies they can assess and map the remaining evidence elsewhere |
| Proposed validator is unresponsive | Use another eligible person with genuine knowledge rather than fabricating or overstating a relationship |
| Validator recalls the event differently | Reconcile the evidence and revise inaccurate or ambiguous wording before notification |
| Project information is confidential | Generalize protected identifiers and values while preserving the decision, responsibility and result |
Common Validator Planning Mistakes
- Choosing professional credentials without checking knowledge of the work.
- Assuming every applicant must use exactly two validators.
- Assigning one person to examples outside their experience.
- Checking licence dates only after the CBA has been drafted.
- Waiting until PEO notification to contact former supervisors.
- Asking validators to match a preferred self-rating.
- Using inconsistent dates, roles or project names across the CBA and experience record.
- Treating a referee as automatically interchangeable with a validator.
- Leaving confidential information unresolved until the validator reviews it.
- Assuming validator agreement guarantees PEO acceptance or licensure.
Validator Readiness Checklist
- The person satisfies the applicable Canadian or international eligibility rule.
- Licence, registration body, jurisdiction and relevant dates have been checked.
- The person has direct knowledge or a clear, credible basis for assessing the applicant’s skills.
- Every assigned competency falls within what the person can validate.
- Contact information is current and the person has agreed to participate.
- The work examples match the experience record, employer, dates and role.
- Personal contributions and approval boundaries are clear.
- Confidentiality concerns have been addressed.
- The validator understands that their rating must be independent.
- The applicant has not assigned more than one validator to the same competency.
Why Professional Support Can Help With Validator Planning
Validator problems often begin earlier than the outreach email. An application may rely too heavily on one project, hide personal contribution behind team language, or contain dates and responsibilities that do not align with the people available to verify them. These gaps become harder to solve after examples are assigned.
A structured PEO competency report review can map evidence to suitable contacts, identify unsupported examples, reconcile the experience record and improve the clarity of applicant-owned work examples. It cannot appoint a validator, create professional standing or replace firsthand knowledge of the work.
Build a validator map around evidence, not convenience
If your experience spans several employers, supervisors or countries, a focused review can help organize the evidence and validator map before the application reaches the notification stage.
Frequently Asked Questions
1. Who Can Be a Validator for PEO?
For Canadian work, the validator must have been licensed as a P.Eng. in Canada when the work occurred. For international work, the person should be a senior engineering practitioner licensed in the jurisdiction and able to provide proof of qualifications if requested. They also need sufficient knowledge of the applicant’s skills and assigned evidence.
2. How Many Validators Do You Need for PEO?
There is no universal requirement for two. Each work example needs one assigned validator. One person may cover many competencies when eligible and sufficiently informed, while several may be needed across employers, projects or countries. More than one validator cannot be assigned to the same competency.
3. Does a PEO Validator Have to Be a P.Eng.?
For work carried out in Canada, yes: the validator must have been licensed as a P.Eng. in Canada at that time. International experience follows the separate senior-practitioner and local-licensing criteria stated in the current PEO guide.
4. Can a Former Supervisor Validate My Experience?
Yes, when the former supervisor meets the applicable eligibility rule, remembers the work sufficiently and can provide an objective rating. Confirm current contact details and the exact period or projects they can verify.
5. Can a Colleague, Mentor or Client Be a PEO Validator?
They may be considered when they meet the applicable professional requirements and know the applicant’s skills well enough to validate and rate the assigned example. A close working relationship is stronger than a distant professional connection, and PEO decides acceptability.
6. Can an International Supervisor Act as My Validator?
Yes, when the person is a senior engineering practitioner, holds the relevant local licence or professional standing and can provide proof of qualifications if requested. They must also understand the applicant’s work and responsibility.
7. Can a Family Member Be a Validator?
PEO assessors consider family members case by case. Because independence may be questioned, use a suitable non-family validator with strong knowledge of the work when possible.
8. Can Different Validators Review Different Competencies?
Yes. Multiple validators may be used across the CBA. Assign each competency to the person best able to assess it, but do not assign more than one validator to the same competency.
9. What Does a Validator See and Rate?
The validator assesses the work examples assigned to them, confirms the competence and relevant experience, scores each competency using the rating scale and provides feedback. The current portal controls the exact interface and fields shown.
10. What If My Validator Disagrees With My Self-Rating?
Review the evidence and discuss factual differences without pressuring the validator to change an independent view. Applicant and validator ratings are supplementary; PEO assessors apply the final assessment rating.
11. What Is the Difference Between a PEO Validator and a Referee?
A validator assesses assigned CBA work examples and competencies. A referee or reference may support a different application requirement. Follow the current PEO terminology and do not assume that fulfilling one role automatically satisfies the other.
12. What If I Cannot Contact My Previous Supervisor?
Identify another eligible manager, mentor, client or colleague who has enough knowledge to assess the relevant work objectively. If no suitable person exists or eligibility is uncertain, obtain direction from PEO before finalizing the assignment.
