National Dental Assisting Examining Board © 2001 – 2025 National Dental Assisting Examining Board 13 grade will not be reversed from a “U” grade to an “A” grade even if the error is corrected on a re-attempt. For example: In the skill “Applies and Removes Dental Dam”; if the candidate is awarded a “U” grade for the critical criterion “Places clamp in the mouth with safety floss attached” on any attempt, the candidate will also be awarded a “U” grade for the critical criterion “Performs the skill safely and with care”. This technical and patient safety error cannot be corrected on a re-attempt of the skill. The “U” grade will stand even if the error is corrected. This will result in failure of the skill “Applies and Removes Dental Dam”. To review the complete evaluation forms for each skill, please see Appendix A of this handbook. Skill Evaluation Process This is a description of the start-to-end process for how skill evaluation will take place. A treatment prescription will be provided for each skill. A maximum of five (5) minutes will be permitted to read the prescription before beginning the procedure. Candidates will be able to refer to the treatment prescription at any time during the performance of the skill. Treatment prescriptions will include the time limit. Where skills include a placement and removal (such as “Applies and Removes Dental Dam”), both the successful placement and removal will be required during the stated time limit. Candidates must follow the treatment prescription exactly. The product directions for dental materials (if applicable) may also be reviewed within the five (5) minutes thatare permitted to read the prescription. Candidates will be able to refer to the product directions at any time during the performance of the skill. Candidates who are ready to proceed before the five minutes have expired, may advise their Evaluator they are ready to start. Candidates will be directed by their Evaluator to place their mask and put on their gloves. Putting on gloves and placing the mask is not included in the allotted time for the skill. Once the candidate advises their Evaluator they are ready to begin the skill, the timer will be started. Candidates must advise their Evaluator when they are ready to have their work evaluated. At this point, the timer will be stopped and the candidate will be directed to remove their gloves and mask. If the candidate wishes to re-attempt in the allotted time, the candidate MUST informtheir evaluator BEFORE they leave the operatory. Candidates who do not request a re-attempt before leaving the operatory will not be permitted to return to make adjustments to their work, even if time remains to complete the skill. Candidates will be asked to leave the operatory/station to allow the Evaluators to evaluate the product. For the skills “Applies and Removes Dental Dam and Applies” and “Removes Matrix and Wedge”, the candidate will be directed to, and evaluated on, the removal of the dental dam and matrix and wedge BEFORE the reattempt. This is for the benefit of the candidate.
