- D.CE is Diplomate, Coastal Engineering, issued by ACOPNE within ASCE Civil Engineering Certification; the current designation is BC.CE.
- Assessment is a credentials review plus a panel oral assessment, not a multiple-choice test.
- Application fee is USD 350 for ASCE/Institute members and USD 450 for nonmembers.
- Renewal requires a valid PE license, 20 PDHs annually including 2 ethics PDHs, and a USD 200 or 250 fee.
Identity Snapshot: What D.CE Actually Is
This sheet covers one credential only: the Diplomate, Coastal Engineering (D.CE). It is awarded by the Academy of Coastal, Ocean, Port & Navigation Engineers (ACOPNE), which sits inside ASCE Civil Engineering Certification (CEC). The "D.CE" label is a legacy identity; the issuer's current designation is Board-Certified Coastal Engineer (BC.CE). If you see both terms in ASCE materials, they point at the same coastal specialty path.
Because several unrelated credentials share the D.CE letters, confirm every fact you study against ACOPNE and CEC sources. For the naming background, see our explainers on what D.CE stands for and what D.CE certification is.
Eligibility at a Glance
Eligibility is governed by CEC Rule 3, Baseline Requirements for Post-Licensure Certifications (revised 1 July 2024). The core elements are:
- Active coastal practice.
- Education: a relevant bachelor's degree from an ABET-accredited program, or an accepted relevant postgraduate substitute.
- Licensure: a current PE license or approved equivalent.
- Experience: 10 progressively responsible years after the bachelor's degree, including 8 in coastal engineering.
| Pathway | Total Experience | Coastal-Specific Experience |
|---|---|---|
| With qualifying postgraduate education | 10 years post-bachelor's | 8 years |
| Without qualifying postgraduate education | 15 years | 13 years |
| Permanent resident working in a country with no PE or approved equivalent | 15 years | 13 years |
Qualifying postgraduate education means a relevant postgraduate degree, at least 30 relevant academic postgraduate credit hours, or a recognized advanced certificate. Continuing education units are not equivalent to academic postgraduate credit hours, so do not count seminars toward that threshold. A relevant master's degree earns 1 year of experience credit; a relevant PhD earns 3 years.

Application Evidence and References
The application package centers on two items:
- A CV documenting your coastal career and responsible-charge roles.
- At least 3 licensed PE references from 3 different organizations.
The "3 different organizations" rule is where applicants stumble. Two references from the same employer count as one organization, so line up referees across employers, clients, or agencies early. Choose people who can speak to your technical judgment and your responsible charge on named projects, since the oral panel will probe those same projects.
How the Assessment Works
The assessment has two parts: a credentials review and a panel oral assessment. The issuer notes the oral assessment may be waived in rare circumstances, but plan as though it is required.
Oral Assessment Mechanics
When the oral is required, it unfolds in a fixed order:
- A 30-minute project/career presentation comes first. The 30 minutes covers the presentation only, not the full session.
- Panel questioning follows.
- Unseen professional-judgment scenarios may also be posed.
The panel evaluates four things: advanced technical competence, responsible charge, continuing development, and current technical practice. The coastal Body of Knowledge also expects licensure-level competence across the Civil Engineering Body of Knowledge (CEBOK) outcomes plus mastery of at least one advanced technical outcome. In practice, you should be able to name your area of depth and defend it with project evidence.
Key Takeaway
Build your 30-minute presentation around projects where you held responsible charge, and choose one advanced technical outcome you can discuss at expert depth. Rehearse the unseen-scenario portion by talking through judgment calls aloud, since you cannot predict the scenario.
To gauge how demanding this route is compared with a written exam, see How Hard Is the D.CE Exam?.
The Four Competency Areas
ACOPNE's coastal Body of Knowledge lists competency categories that this site uses as four unweighted preparation headings. They are not an official exam-domain count, the issuer does not publish percentage weights, and the list does not establish exhaustive coverage. Treat them as a scaffold for your preparation. Our complete guide to the four content areas expands each one.
Domain 1: General Knowledge
The licensure-level foundation across CEBOK outcomes, plus professional practice.
- Be ready to show breadth across civil engineering fundamentals, not only coastal topics.
- Prepare to discuss ethics, responsible charge and current technical practice.
- Know which advanced technical outcome you are claiming mastery in.
Domain 2: Hydrodynamics and Environmental Forcing
The physical drivers acting on coastal projects.
- Waves, water levels and currents as design inputs.
- How environmental forcing translates into loads and design conditions.
- Defending the assumptions and data sources behind your project analyses.
Domain 3: Beach and Shoreline Stability, Protection and Coastal Structures
The core design domain for most practitioners.
- Shoreline response and stability concepts.
- Protection approaches and the performance of coastal structures.
- Explaining why a solution was chosen over alternatives on your own projects.
Domain 4: Construction, Maintenance and Monitoring
The lifecycle side of coastal work.
- Constructability and field decisions.
- Maintenance strategy over a structure's life.
- Monitoring programs and using performance data to adapt practice.
A practical note: because panelists question from your own presented work, the domains function less as chapters to memorize and more as lenses a panel can apply to any project you show. Prepare each project so it can be examined through all four.
Fees, Deadlines and Retake Rules
Fees and retake authority come from the CEC Bylaws and Rules (October 2025 compilation, Rule 4 revised 13 October 2025).
| Item | ASCE and/or Institute Member | Nonmember |
|---|---|---|
| Nonrefundable application fee | USD 350 | USD 450 |
| Annual renewal fee | USD 200 | USD 250 |
The application fee is nonrefundable and covers the review, the oral assessment and initial certification, so there is no separate exam fee layered on top. Two timing rules matter:
- Required assessments must be completed within 12 months of application acceptance.
- One retake is allowed on request within that same 12-month period.
Because the retake shares the same 12-month window, do not schedule your first attempt at the very end of it. Leave room to request and complete a retake if needed. For the full cost picture, including membership considerations, see D.CE Certification Cost: Complete Pricing Breakdown.
Validity and Renewal Numbers
Initial certification expires on 31 December of the following year, then renews annually. Active renewal requires:
- A valid professional engineering license.
- 20 relevant PDHs annually, including 2 ethics PDHs.
- The renewal fee: USD 200 for ASCE and/or Institute members, USD 250 for nonmembers.
Renewal rules are detailed in the issuer's Maintain Your Certification page and its Continuing Professional Development Requirements and Procedures document. Weighing these ongoing obligations against the credential's benefits is covered in Is the D.CE Certification Worth It?
What the Issuer Does Not Publish
Many candidates search for numbers that the reviewed current issuer sources simply do not provide. As of the 7 October 2026 verification, none of the following is specified:
- Official percentage weights for the four competency headings.
- A separate exam code or version.
- A fixed question count.
- A full assessment duration (only the 30-minute presentation is stated).
- A numerical pass mark.
- An official pass rate.
Treat any site quoting these figures as unverified. Our pages on the passing score and pass rate explain what can and cannot be said responsibly. Likewise, salary expectations vary by employer and region and are not guaranteed by the credential; see the salary guide for qualitative context, and exam dates for scheduling guidance.
A Domain-Ordered Prep Sequence
Since the assessment is portfolio-and-oral based, sequence your preparation around the four headings rather than around generic study habits. One workable ordering:
Domain 1 and Eligibility Paperwork
- Confirm your experience-year math against CEC Rule 3.
- Line up 3 PE references from 3 different organizations.
- Choose your advanced technical outcome.
Domain 2: Hydrodynamics and Environmental Forcing
- Revisit the forcing assumptions behind each presented project.
- Practice explaining data sources and uncertainty aloud.
Domain 3: Shoreline Stability, Protection and Structures
- Prepare alternatives-analysis narratives for your key designs.
- Draft the 30-minute presentation outline.
Domain 4 and Mock Panels
- Prepare construction, maintenance and monitoring examples.
- Run timed rehearsals and unseen-scenario drills with colleagues.
Domain 3 sits in the middle because it usually anchors the strongest project evidence, while Domain 4 comes last so lifecycle discussion can tie the earlier material together before mock panels. For a broader plan, see our D.CE study guide, and for question-style rehearsal on supporting technical fundamentals, try the practice tests. Note that practice materials are study aids, not an official question bank.
