Certification Renewals

Recertification is a mandatory process that provides assurance that a certificant is actively maintaining his or her knowledge and skills. This process must be completed before the end of every 2-year certification cycle. The first recertification cycle begins on the date of initial certification and expires two years after that initial date of the certification. Your WPI Voluntary Certification must be renewed every two years. Please log in to your Certemy account to complete the renewal steps. Each renewal must be submitted with 24 hours of continuing education, a signed attestation, and a renewal fee of $110. If your certification has been expired for more than 6 months, a late fee of $35 is added to the renewal fee. If your certification has expired for over two years, you will not be able to renew, and may have to retest.


Contact Hour Equivalencies

Post-secondary and continuing education can be converted to contact hours. We understand that many units of post-secondary or continuing education exist and will do everything possible to fairly equate units when reviewing applications and submitted documents.

​FIFTEEN CONTACT HOUR

Approved topics for recertification

All continuing education submitted for recertification credit must be on approved topics. Recertification credit will not be given for presentations, writing/publishing articles, or teaching courses. Annual meetings, conferences, and workshops that meet approved topic guidelines may be accepted for continuing education credit if a certificate of attendance with contact hours is provided.

Related Course Subjects

All post-secondary education submitted for eligibility credit must be related. Credit will not be given for presentations, writing/publishing articles, or teaching courses.

Annual meetings, conferences, or workshops covering relevant subjects may be accepted for post-secondary education credit if a certificate of attendance with contact hours or CEUs is provided along with an agenda of the event.
