Both CMRP and CMRT recertification forms may be accessed here. You will have to create an account if you do not already have one prior to login.
You may renew up to 365 days before your expiration date and up to 90 days after you expire.
If you have not renewed after you have expired you will need to submit a new application, pay and retake the exam.
You will not be able to see the recertification forms if you are not in the correct date range.
Recertification deadline extensions are available on a limited bases in cases of extenuating circumstances. You must submit an extension request before your certification expires.
