NBC has long been working to integrate digital technologies into its examination process for the Certified Dental Technician (CDT) credential. As part of NBC's efforts to continue to evolve its certification programs, NBC is developing a new CDT specialty in Digital Workflow. NBC has contracted with JML Measurement & Testing Services, LLC, to guide it through the creation of this new CDT specialty in Digital Workflow.
During the 2nd quarter of 2022, NBC created a task force charged with exploring the creation of a new certification for digital technicians. The task force worked to perform a job task analysis for digital workflow. NBC sent the draft job task outline to its communities of interest to validate the work of the task force. Using the responses from the communities of interest, NBC has finalized a job task outline and a written examination blueprint for the new Digital Workflow CDT specialty.
The Digital Workflow CDT specialty examination will consist of four domain areas as follows:
Thank you to the Foundation for Dental Laboratory Technology for their sponsorship of the development of the Job Task Analysis.
- Domain I: Data Acquisition (21 - 25% of written examination questions are from this domain)
- Domain II: Design Indications (30 - 34% of written examination questions are from this domain)
- Domain III: Fabricating Restorations (22 - 26% of written examination questions are from this domain)
- Domain IV: Maintaining Digital Equipment (20 - 24% of written examination questions are from this domain)
During the 3rd quarter of 2022 NBC worked with numerous volunteers to assist with writing draft examination questions for the Digital Workflow CDT specialty. During the 4th quarter of 2022, NBC worked with another task force to review each question that was submitted by a volunteer.
NBC pilot tested the written examination questions in conjunction with the LMT Lab Day Chicago Meetings on Thursday, February 23, 2023 and Saturday, February 25, 2023. JML Measurement & Testing Services, LLC, along with another task force, reviewed the written examination data and conducted a standard setting process to determine a cut score for the written examination form.
NBC worked with a task force to develop the components of the practical examinations for the Digital Workflow CDT specialty. A draft practical examination was created and pilot tested in August 2023, and again in October 2023. The task force reviewed the data from the pilot tests and in November 2023 conducted a standard setting process. From the standard setting, a cut score was determined for the practical examination. The Digital Workflow Practical Examination was then launched in January 2024.
