The General Chairside (GC) exam is a component of the Certified Dental Assistant (CDA) certification. This examination is designed specifically for dental assistants who wish to demonstrate their knowledge and competency in foundational dental assisting skills. Achieving this certification validates your expertise and commitment to the profession. It is an essential step for those looking to advance their careers and prove their proficiency in general chairside duties.
The path to passing the General Chairside exam involves mastering a wide array of skills essential to the daily operations of a dental office. The underlying knowledge base includes understanding proper patient care, preparation, and safety protocols. You will be expected to know the names and functions of various dental instruments used during restorative and specialty procedures.
The curriculum typically covers:
Patient chart review and legal documentation.
Four-handed dentistry techniques and instrument transfer.
Moisture control and isolation techniques (including dental dam application).
Mixing and placing dental materials (liners, bases, cements, and impression materials).
Obtaining and recording vital signs.
Chairside assisting during various dental procedures (fillings, root canals, crown preparations, etc.).
Oral anatomy, physiology, and dental terminology.
Sterilization and disinfection procedures in the operatory.
The exam itself is a rigorous assessment of this knowledge. It is a computer-based test, typically comprised of 120 multiple-choice questions.
When you sit for the General Chairside exam, you will need to manage your time effectively. The time limit for the GC exam is 90 minutes.
The scoring is based on a scaled score system. To pass, you generally need to achieve a scaled score of 400 or higher. The specific difficulty of the questions you answer determines your final scaled score, ensuring a fair assessment regardless of the specific test form you receive.
Specific rules include:
No outside materials (notes, books, or electronic devices) are allowed in the testing room.
You must present valid, government-issued photo identification.
You should arrive early at the testing center to complete the check-in process.
Effective preparation is the key to success on the General Chairside exam. It is highly recommended that you:
Utilize practice exams extensively: Taking timed practice tests will help you become familiar with the question format, manage your time, and identify areas where you need further study.
Review the official exam blueprint: The Dental Assisting National Board (DANB) provides a detailed outline of the topics covered, which should guide your study plan.
Use multiple study resources: Combine textbook learning with online review courses, flashcards, and study groups.
Focus on practical application: Understand why a certain procedure or technique is used, not just how.
The exams are administered through Pearson VUE, which has authorized testing centers located throughout the United States and Canada. You can schedule your exam at a center and time that is convenient for you through the Pearson VUE website after your application has been approved. Some dental assisting schools may also serve as authorized testing sites.
