DER Exam

Register for the DER Exam


Examination Scoring and Reporting

All certification candidates will receive written notification of their exam scores as follows: 1) at the conclusion of the exam; 2) as a printable pdf report under that CP-ID at 3) in the form of a certificate mailed to you within two weeks of completion. No exam scores will be reported over the telephone.

The pdf and the results shown at the conclusion of the exam notifications will indicate the number of questions missed and whether this constitutes a passing or failing score. Applicants for certification must receive a score of 80%.

Pass Fail Standard

The passing score on the C-DER examination is based on a minimal level of knowledge that is expected of passing candidates. Each candidate is measured against a standard of knowledge, not against the performance of other individuals taking the examination.

Appeals Process

Within 30 days of taking the exam, unsuccessful candidates may appeal their results to the DATIA Education/Standards Committee. Candidates should submit the question that is being appealed and any documents to support the answer provided by the candidate. These materials should be sent to the attention of the DATIA Education/Standards Committee at DATIA's headquarters (attn: exam appeals) in written hard copy form with a signature of the petitioner.

The committee will review the appeal and respond to the candidate within 30 days. The committee's decision is the final decision and cannot be further appealed by the candidate of DATIA.

Examination Honor System

Candidates for certification exams are required to verify that they have not received any assistance in completing the certification exam beyond the allowed reference materials. Specifically, candidates are not permitted to seek assistance from other C-DERs, jointly complete exams, or use exams taken previously by themselves or other candidates when completing the exam. Use of any of these means is considered cheating.

If a candidate is suspected of cheating in completing their exam, they will be given the reasons for such suspicion and offered the opportunity to explain the circumstances. All information concerning the reasons for suspicion and follow-up information from the candidate will be forwarded to the Education/Standards Committee (candidate's name and any identifying information will be withheld), who will vote and determine if cheating has occurred.

If the committee determines that cheating has occurred, the candidate will be ineligible for certification until the next certification year. If the committee determines that cheating did not occur, the candidate's score on the exam will stand.


Candidates who fail to achieve a passing score on the DER exam will be offered the opportunity to take the exam a second time within 60 days for no charge. The second exam will cover the same material as the original exam, but may contain different questions.

Should a candidate register to take the retest after the 60-day period has elapsed, the candidate must remit the full certification fee with the registration form. 

A candidate can take the certification exam twice during the certification year, which runs June 1 to May 31. Should a candidate fail to pass the examination after two attempts in one certification year, they will need to wait until the following June to re-register for the examination.


Recertification is required every two years in June. This recertification is achieved through a certification renewal exam. . DATIA C-DERs will be notified prior to their certification expiration of the need to recertify.

The recertification exam will be the same as the initial certification exam for the current year. This examination will cover items intrinsic to C-DERs to include any and all new regulations, guidelines, and or procedures that have been enacted since the C-DER received their initial certification. All of the above policies and procedures apply when recertifying.

Certification examination fees also apply to recertification.
