CRE Recertification Overview
Earning your Certified Reliability Engineer (CRE) certification from the American Society for Quality (ASQ) represents a significant professional achievement, but maintaining it requires ongoing commitment through the recertification process. With CRE certifications valid for three years from the date of issue, understanding the recertification requirements, costs, and timeline is crucial for preserving your professional credentials and continuing to benefit from this valuable certification.
The CRE certification, governed by ASQ and accredited by ANAB under ISO 17024, maintains its value through rigorous recertification standards. Given the significant ROI that CRE certification provides, staying current with recertification is essential for continuing to leverage the career benefits and salary premiums associated with this credential.
Your CRE certification expires exactly three years from your certification date. Mark this date in your calendar and begin planning for recertification at least six months before expiration to ensure you meet all requirements on time.
Recertification Requirements
ASQ provides CRE holders with two pathways to maintain their certification: earning Recertification Units (RUs) or retaking the full examination. The RU pathway is designed to encourage continuous professional development while allowing practitioners to maintain their certification without the stress and expense of re-examination.
Primary Requirement: 18 Recertification Units
The standard recertification path requires earning 18 Recertification Units within your three-year certification cycle. These units must be earned through approved professional development activities that demonstrate your continued engagement with reliability engineering principles and practices.
RUs can be earned through various activities, but they must be directly related to reliability engineering or the five domains covered in the CRE Body of Knowledge:
- Reliability Fundamentals (19.3%)
- Risk Management (16.7%)
- Probability and Statistics for Reliability (22.7%)
- Reliability Planning, Testing, and Modeling (22.7%)
- Lifecycle Reliability (18.7%)
Alternative: Retake the Examination
If you prefer not to pursue RUs or cannot accumulate the required 18 units, you may choose to retake the full CRE examination. This option involves the same exam fees and preparation requirements as initial certification, including the $450 fee for ASQ members or $550 for non-members.
If your certification expires before you complete recertification requirements, you'll need to retake the full exam and cannot use the RU pathway. Plan accordingly to avoid losing your certified status.
Understanding Recertification Units (RUs)
Recertification Units are awarded based on participation in qualifying professional development activities. Understanding how RUs are calculated and which activities qualify is essential for efficient recertification planning.
RU Calculation Methods
Different activities earn RUs at different rates. Here's how the major categories work:
| Activity Type | RU Calculation | Maximum RUs |
|---|---|---|
| Professional Education | 1 RU per contact hour | 18 RUs |
| Presenting/Teaching | 2 RUs per contact hour | 9 RUs |
| Publishing Articles | 4 RUs per article | 8 RUs |
| Book Authoring | 8 RUs per book | 8 RUs |
| Volunteer Work | 1 RU per 10 hours | 6 RUs |
| Professional Meetings | 1 RU per day | 3 RUs |
Qualifying Professional Education
The most common way to earn RUs is through professional education activities. These include:
- University courses related to reliability engineering
- Professional development seminars and workshops
- Online courses from accredited providers
- Industry conferences with educational sessions

While recertification involves ongoing costs, the salary premium for CRE holders typically ranges from $8,000-$15,000 annually, making the investment in maintaining certification highly worthwhile financially.
Timeline and Deadlines
Proper timeline management is crucial for successful CRE recertification. Missing deadlines can result in certification lapse and require retaking the full examination.
Three-Year Certification Cycle
Your CRE certification is valid for exactly three years from the date of initial certification or last recertification. Key timeline considerations include:
- Year 1: Begin accumulating RUs immediately
- Year 2: Assess progress and plan remaining activities
- Year 3: Complete final RUs and submit recertification application
Application Submission Windows
ASQ accepts recertification applications within specific timeframes:
- Early Submission: Up to 90 days before expiration
- Standard Window: 60 days before expiration
- Final Deadline: Certification expiration date
- Grace Period: 90 days after expiration (additional fees apply)
During the 90-day grace period, additional fees apply and you cannot represent yourself as certified. Plan to submit your application well before the expiration date.
RU Accumulation Timeline
RUs must be earned during your current certification period. Activities completed before your certification date or after expiration do not count toward the current cycle. This makes timing crucial for:
- Conference attendance
- Course completion dates
- Publication dates for articles
- Volunteer work periods
Documentation Requirements
Maintain thorough documentation throughout your certification cycle:
- Certificates of completion
- Conference attendance records
- Course transcripts
- Publication copies
- Volunteer service verification
