Public Training (Free Access)

The public training option is a no-charge option available to individual trainees wishing to be trained online. Minimal technical support is provided. Access to an expert for training questions is not provided. It is expected that trainees who take the online training are already familiar with the Clinical Dementia Rating (CDR®) Dementia Staging Instrument. A certificate is automatically presented on-screen for those who pass the training. The certificate can be downloaded as a PDF. A limited set of remedial modules is automatically assigned for trainees that fail their initial training modules.

Training is divided into two different paths:

  • Full Training
    • 10 modules: Overview of the CDR, 3 training modules, 6 reliability modules
    • Generally intended for those previously uncertified or certified more than 5 years ago
    • Each module’s interview video averages 40 minutes of playtime
  • Refresher Training
    • 5 modules: 1 training module, 4 reliability modules
    • Generally intended for those previously certified within the past 5 years but want/need a refresher in the CDR
    • Each module’s interview video averages 40 minutes of playtime

If you are taking the training for a clinical trial, you should reach out to your study coordinator or study manual to determine which training path your trial requires that you attempt. Trial sponsors are free to set their own timelines for CDR recertification. The Knight ADRC cannot provide guidance in regards to your trial’s specific training requirements.

As of 11/30/2023, public training now provides CDR training with video subtitles in the languages listed in the table below. Access to module-specific worksheets in the same languages are also provided as part of the public training via a Box link; however, a Box account is NOT required to access/download the module-specific worksheets.

Private Training (Research Studies, Clinical Trials)

NOTE: Securing an online CDR Training contract is different than licensing the CDR Dementia Staging Instrument for use in a research study/clinical trial. While the training provided by the website is strongly encouraged for any CDR rater, it is not mandatory when licensing the instrument with our Office of Technology Management/Tech Transfer.

New, private training contracts are no longer being offered as of 11/30/2023. The public training option mentioned above now provides full access to training in the languages noted. Existing training contracts will continue to operate until the end of their contract period at which point all CDR trainees will be directed to the public training option.

Taking contracted, study-specific training?

If you are a CDR trainee that is part of a contracted research study or clinical trial, use the button below to access the training application. You will be able to select your specific, contracted study/trial within the application. If your study/trial isn’t listed in the application, it is not a contracted training. You will automatically be assigned the free CDR Training.

Make sure that you have your study/trial’s password ready. Once you submit the application, you will be prompted to enter the password in order to begin the training. If you do not have your trial’s password, you will need to contact your study’s coordinator or trial manager. The Knight ADRC will not provide the password.

Confidentiality Protection

The CDR Online Training System utilizes video segments of real, patient interviews. All interview participants provided informed consent for their images to be shown for appropriate educational purposes. Apart from the visual appearance of each interviewee, there is no other identifying information in these interview segments. Nevertheless, we ask that approved trainees (1) respect the confidentiality of those they observe and (2) refrain from discussing interview content with others.
