Please be advised that the 2025 ROHT® examination dates are:

April 26, 2025 (application deadline is February 1, 2025)

The applications for the ROHT® examination processes must be received by the CRBOH before the deadline to be considered for eligibility to challenge the exam in that same year.

3. Payment of application fee ($350)
4. Professional references sent from all required references.

Note that upon review of application, additional information may be requested by CRBOH in support of the application.
