The CDGP application requires a non-refundable $175 application fee and third-party employment verification.The Applications to take IHMM examinations expire 12 months from the date your application is approved.  You must complete the examination within that time, or you will have to start over as a new candidate, and meet whatever requirements are in effect at that time.

Special Testing Accommodations

IHMM complies with the Americans with Disabilities Act 1990 (42 USC 12101 et seq), as amended [ADA], and is interested in ensuring that no eligible individual is deprived of the opportunity to take the exam solely by reason of a disability as defined under the ADA as long as the disability is not one which would render the individual incapable of performing the duties of a certified position.  Candidates who require special accommodations must declare the need for a testing accommodation on the online application itself.  There is a checkbox for the applicant to affirm their declaration for special needs accommodations based on the ADA.  The reason for the accommodation must be recognized under the ADA from a qualified professional who has provided evaluation and treatment to the candidate and the candidate will be informed of any documentation requirements. 



IHMM will, under certain circumstances, send a proctor to personally administer a secure examination. In order to meet the requirements to have an IHMM onsite proctored examination you need to be aware of the necessity to execute the IHMM Professional Services and Hosting Agreement. Read this document carefully, as there are specific requirements imposed on every entity seeking an onsite proctored examination rather than taking the IHMM examination at one of our Kyterion HOST® network examination sites

Certification Agreement and Disciplinary Policies

IHMM is committed to upholding the highest ethical standards in the profession. Candidates for certification are required to agree to the Certification Agreement (CA) for their credential or designation as a condition of applying to sit for an examination. Failure to do so will result in denial of certification.

It was developed to safeguard the reputation of the CHMM, CHMP, CDGP and CDGT programs, and in the interest of protecting the public. Also included in the CA is the applicant Consent Statement and the policy informing candidates that email is the primary point of contact and must be up to date at all times. 

Certificants found to be in violation of the Code of Ethics are subject to an investigation of the violation, which may result in sanctions.  All sanctions are subject to appeal.  Following the exhaustion of appeals, the outcome of investigations resulting in sanctions shall be made public, and the notice will include the name of the certificant, the section(s) of the Code violated, and the sanction imposed
