  • How many questions do I have to answer correctly to pass an exam?

    DANB uses computer adaptive testing (CAT) to present questions (sometimes called items) to candidates. This method of testing does not provide a candidate with a percent of questions that must be answered correctly to pass the exam. Instead, the questions come from a pool of questions that have been pretested and calibrated.

    Each candidate starts with a question at or around the passing standard (400). If the candidate gets a question correct, the next question will be slightly harder. If the question is incorrectly answered, the next question will be slightly easier. Question selection always takes into account the content of the question, as each candidate is presented with the same percentage of questions from each content area on the exam blueprint. Using this method of testing, DANB is able to more accurately pinpoint a candidate’s ability level. The average candidate will get a little over 50 percent of the questions correct and a little under 50 percent of the questions incorrect. The candidate’s score is based on the difficulty of the questions that were presented and passed.

  • What if I do not pass all of the component exams to earn certification?

    If you do not pass all of the component exams to earn NELDA, CDA, COA, CPFDA or CRFDA certification, you only need to reapply for the component exams that were not passed. All necessary component exams must be passed within three to five years (three years for NELDA, CPFDA and CRFDA) to earn certification. Certificates of knowledge-based competency will be issued when you pass the RHS, ICE, CP, TA, TF, SE, AMP, IM, TMP or IS component exams. (Please note: Certificates of knowledge-based competency are not certifications.)

  • Will anyone else receive my exam results?

    DANB takes your privacy very seriously. We will only send your exam results to you or, upon request, to a state dental board or regulatory agency to comply with state requirements. DANB also releases grouped exam results to program directors. Please keep in mind that whether you hold a DANB certification or certificate of knowledge-based competency is public record, so DANB will verify this information on request to anyone on request over the phone. DANB also offers an online credential verification tool on its website, which anyone can use.

  • What if my name or address changes after I have applied for an exam?

    It is your responsibility to contact DANB with name or address changes or any spelling errors in your name. DANB charges a $25 fee for reprinting a certificate for a name change once the original certificate has been printed. If you move after applying for an exam, you can update your address in My Account. If your name has changed, please call DANB.

  • What is DANB's retest policy?

    If you have failed an exam, per DANB’s retest policy you may immediately submit a new application form along with the fee and documentation (if required). State regulations may require additional coursework after failed attempts. Check with your state dental board for more information.

  • What is DANB's hand scoring policy?

    Hand scoring of an exam is available on request. Candidates must submit a Request for Hand Scoring of Exam Results (PDF) form along with a $50 hand scoring fee by mail or fax so that it is received within 30 days after the official score date printed on the exam results or certificate. Hand scoring is typically completed within 30 days of receipt of request. If the pass/fail status is reversed as a result of the hand scoring, the $50 fee will be refunded. Requests for hand scoring of an exam will not be honored after 30 days past the official score date.

  • Can I get duplicate exam results?

    Duplicate exam results are available for exams taken within five years of the date of the request. You may request a duplicate exam result by logging in to your Account or submitting a Request for Duplicate Exam Results (PDF) form, along with a $25 fee, for each exam result. Exam results older than five years are not available, though DANB will verify certifications or certificates of knowledge-based competency earned more than five years ago.

    Note: Exam results will not be released to employers or any other individuals, except upon written request of the candidate or as required by state regulatory agencies. Verification of a DANB certification or RHS, ICE, CP, TA, TF, SE AMP, IM, TMP and IS passing status is available from DANB.

  • Can I get a duplicate certificate?

    An individual who has earned a DANB certification may purchase a duplicate certificate. Individual RHS, ICE, CP, TA, TF, SE, AMP, IM, TMP and IS certificates are also available. Candidates with expired certifications may only request duplicate certificates if the certification was earned on June 1, 1993, or later for the CDA or June 1, 1994, or later for the COA. You may request a duplicate certificate by logging in to your Account or by submitting a Request for a Duplicate Certificate (PDF) form and a $25 fee to DANB.

  • Who can request a verification of certification or of a certificate of knowledge-based competency?

    DANB will verify certification or an RHS, ICE, CP, TA, TF, SE, AMP, IM, TMP or IS certificate of knowledge-based competency exam pass/fail status and the effective date(s) to anyone on request, since this information is a matter of public record. Only a candidate, certificant or employer may request verification in writing by submitting a Request for Verification form via mail or fax along with a $10 fee to DANB. The $10 fee covers one verification letter, which can be used to verify multiple certificates, certifications or passing status of one or more exams. An official verification letter is not a duplicate certificate.

  • How can I appeal a DANB decision?

    To appeal a DANB decision regarding eligibility, administrative or exam content issues, you may submit a Request for Reconsideration Under DANB’s Review and Appeal Process form and a $25 appeal fee to DANB’s Executive Director within 30 days of the date on the DANB correspondence that prompts the appeal (i.e., the date on the letter indicating your application was incomplete, date on your exam results letter). Contact DANB for questions about DANB’s appeal policy or process.
