Qualified candidates may apply to take the examination by submitting an electronic application online via the CRDTS website. Once application is made online, additional portions of the application must be submitted by mail.
A fully executed application complete with the appropriate documentation and fee is required to take the examination.
After completing the online application, the following items must be mailed to the CRDTS Central Office.
Proof of Graduation:
     2021 Accredited Graduates: Candidates who have not yet graduated and will be taking the examination for the first time, must submit a “Letter of Certification” (a form provided by CRDTS) signed by their Program Director stating that they will have successfully completed a prescribed course of study in an accredited dental hygiene program within 60 days of the exam date. The “Letter of Certification” serves to verify that the candidate has demonstrated sufficient clinical competence, is in good standing and is anticipated to have met all school requirements by the time of graduation. For programs with multiple applicants, Program Directors may submit one blanket “Letter of Certification” on official letterhead with a list of all eligible graduates.
      Pre-2021 Accredited Graduates: Candidates who have graduated before the present year of testing, must furnish a certified or notarized copy of their diploma or provide a letter on official letterhead from their school of graduation signed by the Program Director verifying their name and date of their graduation.    
      Non-Accredited Graduates: Candidates who graduated from a dental hygiene school outside of the United States and/or Canada must be authorized to take the examination by at least one State which accepts the results of the CRDTS examination. Therefore non-accredited graduates must furnish a letter from that State indicating that they are eligible for licensure in that State upon successful completion of the CRDTS examination. In addition, a copy of the candidate’s dental hygiene diploma with an English translation must be provided. 
Examination Fee: The examination fee is $1025. The fee must be paid at the time of application. Applications submitted must include payment online via VISA/MASTERCARD or submit a cashier's check or money order with the applicant’s candidate ID number written in the lower left-hand corner by mail. No personal checks are accepted for payment.
Confirmation of Training to Administer Local Anesthesia: Candidates who are or will be qualified to administer local anesthesia must submit proof (ex: local anesthesia certificate) verifying appropriate educational and clinical training. For programs with multiple applicants, Program Directors may submit one blanket letter on official letterhead with a list of all eligible graduates verifying training to administer anesthesia. Candidates in states where local anesthesia administration by dental hygienists is NOT permitted or for candidates who will NOT be qualified to administer local anesthesia upon licensure will have the opportunity to have a qualified practitioner administer local anesthesia for them. 
As part of the online application, candidates will be asked to provide the following:
Testing Site Selection: While every effort will be made to grant applicants their first choice in testing sites, it is not always possible to do so. Consequently, candidates are asked to enter 3 testing site choices.
Social Security Number: Candidates must enter their US government-issued social security number. The social security number will be encoded for security purposes, and a new 10 digit Candidate ID number will be generated. When the candidate’s examination results are processed, the 10 digit Candidate ID number will connect the results back to the candidate’s permanent record. 
Photograph: Candidates must upload and submit a digital photograph. The photograph must be recent and of passport quality. It may be in black & white or color, JPG/JPEG, FIG, or PNG formats, square (2”x2”) and must have minimal resolution of 200x200 and maximum resolution of 500x500.
Signature of Candidate: The candidate will sign the online application electronically. The electronic signature is legally binding and has the full validity and meaning as the applicant’s handwritten signature. With the signature the applicant acknowledges that he/she has read and understood the application and the CRDTS Dental Hygiene Candidate Manual and agrees to abide by all terms and conditions contained therein. 
Other General Application Information and Policies are as follows:
Professional Liability Insurance: Insurance in the amount of $1,000,000 / $3,000,000 is required. The Medical Protective Company of Fort Wayne, IN, in cooperation with CRDTS, will provide complementary professional liability coverage, in the required amount, for all candidates taking this examination. Coverage is automatic and no action or payment is required by the applicant. 
Application Deadlines: The application deadline for all exams is approximately 40 days before the date of the examination. Applications and all required documentation must be received by the testing agency on or before the published deadline date. It should be noted that for both the application and the required documentation, the testing agency uses the ‘date of receipt’ (not the ‘date of postmark’) and assumes no responsibility for insufficient postage or delays caused by the post office or other delivery agencies. Applications will be processed on a first-come, first-served basis.
Application Confirmation: Candidates will receive an email to acknowledge receipt of application once all required documentation is submitted.
Exam Testing Site, Date & Time Confirmation: Candidates will receive an email approximately 10 days after the deadline date for their assigned exam which will include the following information, attachments and/or links: 
  • A letter from CRDTS confirming your assigned exam site, exam date and exam time. This letter will also include your newly assigned one or two digit Candidate Number.
  • An attached letter from the school serving as a testing site providing general information about their facilities, policies and usage fees. This letter may also contain information related to nearby hotels and other information and/or forms which are required by the testing site. This letter will also include information on the school’s “Testing Site Fee” with a deadline for payment: All testing sites charge a site fee for use of their clinic facilities, supplies and disposables. Testing sites set their own fee and deadline for advance payment. The “Testing Site Fee” must be remitted to the school, not to CRDTS. 
Candidates taking the examination at a dental hygiene school other than their own are encouraged to visit the site prior to the time of the examination. It is the responsibility of the candidate to make arrangements with the school for the provision of equipment if required and to ascertain whether the appropriate equipment is available.
Exam Assignment & Schedule Changes: Examination assignments (day and time of testing) are considered final when issued and emailed to the candidate. School personnel do not have the authority to accept a candidate for examination at their site or to make assignment changes within an examination series. Such arrangements made between school personnel and candidate may preclude the candidate from being admitted to the examination, as well as, forfeiture of fee.
Disqualification: After applying, a candidate may be disqualified to sit for the exam by their Program Director (or designated school official) for any reason within their discretion. Notification of disqualification by the Program Director must be sent to and received at CRDTS Central Office in writing at least 14 calendar days prior to the start date of the candidate’s scheduled examination. Disqualification is considered final and a candidate will not be reinstated for the examination schedule during that academic year. 
Fees paid by candidates who are disqualified shall be forfeited. Candidates who are disqualified shall have access to the examination upon graduation and presentation of a diploma or in a subsequent academic year in which the candidate has been appropriately certified by the Director (or designated school official). A new application must be submitted with all required documentation and appropriate fee. The applicant will be notified by CRDTS when official notification of disqualification has been received and recorded.
Administrative Fee: An administrative fee of $100 is included in the examination fee. This administrative fee is non-refundable and deducted from all returned application fees. Under certain circumstances, such as moving a candidate to an alternative examination site to accommodate a candidate’s request or conflicts, an additional $100 administrative fee will be assessed. In such cases the candidate will be notified accordingly. 

Incomplete Applications:  It is the candidate's responsibility to ensure that all application requirements are met and that all required items are received in CRDTS Central Office prior to the Application Deadline.  All applications with incorrect or missing information, documentation or fees will be assessed a $100 processing fee and held until the missing item(s) and the fee are received in CRDTS Central Office. Once an exam site has closed, no additional applications will be processed and forfeiture of fees may apply.
Fee Deferral: Under extenuating circumstances the examination fee may be deferred to a later examination. Requests will be considered on an individual basis when received before the candidate’s scheduled exam start date. Requests must be made in writing to CRDTS and must include original documentation in support of the request. Notification will be sent immediately after a determination is made. Should a fee deferral be granted, the terms and conditions for future examination will be included. Requests for fee deferral on or after the date of the scheduled examination will not be considered
Fee Refunds: Notification of cancellation must be made in writing and submitted to the CRDTS Central Office. A refund (administrative fee deducted) will be made if notification is submitted at least 30 days prior to the first day of the examination. A 50% refund will be made if notification is submitted at least 6 business days prior to examination. After that time, any cancellations will result in forfeiture of the entire examination fee. In addition, failure to appear for the exam will result in a forfeiture of the entire examination fee. This policy applies to all cancellations, regardless of reason.
Policy for Reexamination and Remediation
Candidates who are unsuccessful may retake onsite for no additional fee. Candidates who choose to retest at a later exam site will need to apply online and pay the exam fee of $1025.  Candidates are permitted to apply for only one examination at a time and may not submit another application until after the results of the prior examination have been distributed. Candidates who are retaking the examination must fulfill current examination requirements since the examination format is periodically redesigned.
All portions of the failed examination must be retaken, not just the procedures with deficient performance. The candidate applying for reexamination must provide documentation that all school requirements have been completed and the candidate has graduated.
It is the responsibility of each state or licensing jurisdiction to enforce its own remediation policy. There is no state which requires remediation after only one failure; some states may require remediation after two failures. Any candidate intending to seek licensure in one of the states that accepts the results of the CRDTS examination should check with the appropriate State Board regarding its remediation and reexamination requirements. 
It is the responsibility of the candidate to obtain and complete all requirements for remedial education in accordance with the requirements of the licensing jurisdictions in which they seek to obtain licensure. CRDTS does not assume any responsibility in providing this information or in monitoring the completion of such requirements prior to examination.
After three failures, CRDTS requires that the candidate submit documentation from a State which accepts the results of the CRDTS examination verifying that the candidate has completed remediation requirements for that state, and further that the state will accept the results of the candidate’s reexamination with CRDTS.
