The National Dental Examination Clinical Competency (NDECC) exam is one of the most critical steps on the pathway to becoming a certified dental professional in Canada. Designed to assess both clinical decision-making and hands-on skills, the NDECC is divided into two primary components. Naturally, many candidates wonder: If I fail just one part of the exam, do I have to retake the entire NDECC from the beginning?
The short answer is no—you are not required to repeat the entire exam if you only fail one of the two components. However, the process for reattempting the failed portion involves its own rules, timelines, and implications. In this blog, we will walk you through every aspect of this question so that you can fully understand your options, prepare accordingly, and avoid unnecessary setbacks on your path to certification.
What Is the NDECC?
Before exploring the implications of failing a component, it’s important to understand the structure of the NDECC.
The NDECC (National Dental Examination Clinical Competency) is a comprehensive clinical exam that evaluates a candidate’s readiness to practice dentistry safely and effectively. It typically consists of two major components:
-
Clinical Judgment Component
This part assesses a candidate’s ability to make appropriate decisions in clinical scenarios. It may include case-based questions, radiographic interpretation, treatment planning, and other judgment-driven tasks. -
Clinical Skills Component
This involves performing specific dental procedures using typodonts or simulated models. It is designed to evaluate the candidate’s manual dexterity, precision, and clinical technique.
Each component is assessed independently, and performance is scored according to established benchmarks.
What Happens If You Pass One Component but Fail the Other?
If you successfully pass one component of the NDECC but fail the other, you are only required to retake the failed component, not the entire exam. This policy reflects the exam’s modular structure and is designed to reduce redundancy and unnecessary repetition for candidates.
This means:
-
If you pass the clinical judgment component but fail the clinical skills portion, you only need to retake the clinical skills portion in a future exam session.
-
If you pass the clinical skills portion but fail the clinical judgment component, you only need to retake the judgment portion.
This approach saves both time and financial resources while allowing candidates to focus their efforts on improving the specific area of weakness.
How Many Attempts Are Allowed?
The certification process allows candidates a limited number of attempts to pass each component of the exam. While the specific number may change based on evolving policies, most candidates are allowed up to three attempts per component. If you fail a component three times, additional steps such as remedial training or assessment reviews may be required before you can reapply.
It is critical to make the most of each attempt by:
-
Understanding the format and expectations of the exam
-
Participating in preparation courses or mock exams
-
Practicing under exam conditions
-
Reviewing feedback (if provided) from previous attempts
When Can You Retake the Failed Component?
The availability of retake opportunities depends on exam scheduling cycles and seat availability. After failing a component, candidates must register for a future exam session that includes that specific portion. This may mean waiting several weeks or months for the next available date.
Timely registration is important because high demand or limited exam capacity may restrict your options. Preparing well in advance and keeping up with registration timelines will reduce delays in retaking the exam.
Preparation Strategies After a Failed Attempt
Failing any part of a licensure exam can feel discouraging—but it’s not the end of the road. Many candidates pass on their second attempt after making the necessary adjustments. Here’s how to strengthen your chances:
1. Analyze Your Performance
Identify where and why you lost marks. Was it a lack of time? Nervousness? Specific procedures or case-based logic? Pinpointing your weakness allows you to focus your efforts effectively.
2. Seek Professional Guidance
Consider enrolling in a review course or coaching program specifically designed for NDECC preparation. These often provide targeted training, sample cases, simulated clinical tasks, and instructor feedback.
3. Use the Correct Typodonts or Materials
If you failed the clinical skills portion, make sure you’re practicing with the correct materials and typodont models that match current exam standards. Even slight differences can affect your hand performance.
4. Mock Practice Under Exam Conditions
Set up a mock exam at home or in a training center to simulate timing, pressure, and clinical protocols. This builds confidence and readiness for the real thing.
5. Stay Updated on Exam Changes
The examination authority occasionally updates its exam format, assessment tools, and guidelines. Make sure you are following the most current procedures and expectations.
Important Reminders About the NDECC
-
You must pass both components of the exam to receive certification.
-
A passing score in one component is typically valid for a limited time—you must pass the second component within that timeframe.
-
Retake fees will apply each time you register for a component.
-
Certification is only granted after both components are successfully completed and final documentation is submitted.
Final Thoughts
Failing one part of the NDECC does not mean starting from zero. The modular nature of the exam ensures that your success in one area is preserved, and your future attempts can be laser-focused on improvement where it’s needed most. By understanding this structure, you can navigate the exam process more strategically and minimize the impact of setbacks.
With careful preparation, smart time management, and the right resources, most candidates are able to overcome initial challenges and successfully complete the certification process. So if you find yourself facing a retake, don’t be discouraged—take it as an opportunity to come back stronger, more prepared, and ready to prove your readiness for dental practice in Canada.
