Once a certificate has been expired for more than six months, it can no longer be recertified. However, you can acquire an active certificate through our Back-On-Track (BOT) program. More… 

  Re-take exam

4. If a student fails the exam, what are the retake conditions?

You have up to six months from your first exam date to retake the exam. Please contact us to purchase a retake exam voucher.

5. What if a student fails the exam and missed the 6-month deadline to retake the exam?

Please reach out to us for assistance, and we’ll guide you on the next steps.

6. Can a student repeat the ILT/VILT course to prepare for the retake exam?

Yes. If you previously attended the ILT/VILT course, you may request to repeat the class within 6 months of the original training date. Please contact the salesperson who handled your registration. A small fee may apply for ILT sessions to cover facility costs.  

7. Can a student retake the exam from home or office?

Yes. You can retake your EPI certification exam remotely.  

  CDCP, CDCS, CDCE

8. Do I need an active CDCP certificate to enrol in the CDCS course?

Yes. An active CDCP certificate is a pre-requisite for the CDCS. We allow a 6-month grace period after your CDCP expiry during which you may still upgrade to the CDCS without repeating the CDCP course. You’ll have to pass the CDCS exam within this 6-month window.

9. What if I want to attend the CDCS, but my CDCP has expired more than 6 months?

If your CDCP certificate is expired for more than 6 months, you’ll need to refresh your CDCP knowledge before moving on to the CDCS. You can do this with the Back-On-Track (BOT) program. Once you have an active CDCP certificate, you can proceed with the CDCS as normal.

10. My CDCP certificate is expiring soon, and I have the CDCS, do I have to recertify my CDCP?

No, you do not have to recertify your CDCP after you have achieved the CDCS. EPI recognises the highest-level certificate in the CDCP/CDCS/CDCE track, which in this case is the CDCS. You only need to maintain your CDCS certificate.
The same applies to those who have achieved the CDCE. Only the CDCE needs to be maintained.

11. When I recertify my CDCS, will I get a new CDCP certificate as well?

No. You will receive the CDCS certificate only. EPI recognises the highest-level certificate in the CDCP/CDCS/CDCE track, and for CDCS holders, that is the CDCS.
The same rule applies for CDCE. Only the CDCE certificate will be issued.

12. What if I want to attend the CDCE, but my CDCS is expired more than 6 months?

If your CDCS certificate has been expired for more than 6 months, you’ll need to refresh both your CDCP and CDCS knowledge before moving on to the CDCE. You can do this with the Back-On-Track (BOT) program. Once you have the active CDCP and CDCS certificates, you can proceed with the CDCE as normal.

13. Can I purchase the exam only to for my recertification?

No. Recertification is offered through our Recertification Package, a self-study bundle that includes the e-book and exam. EPI course content and exams are updated regularly to reflect industry advancements, ensuring continued value and recognition for your certification.

14. Can I attend CDCP and CDCS consecutively in the same week?

Yes, this is allowed. 

What if I fail the CDCP exam, can I continue with the CDCS training and exam?
Yes, you can attend the CDCS training and exam. However, your CDCS certificate will not be released until you have your CDCP certification.

 

  CTDC, CTIA, CTLA

15. Which courses, apart from CDCP, are approved prerequisite for CTDC?

Please refer to the pre-requisites section on the CTDC webpage

16. Does the CTIA prerequisite need to be on the latest CTDC version?

No, any CTDC version will qualify as pre-requisite for CTIA.

17. What are the pre-requisites for CTLA?

There are two prerequisites for CTLA:

1. CTDC TIA-942 version that matches the CTLA TIA-942 version.
and

2. A valid/active CTIA or ISO 9001 or 27001 Lead Auditor Certificate

 

18. I have to recertify my CTDC/CTIA/CTLA?
 
No. The CTDC, CTIA and CTLA certifications are issued for the standard version and do not expire.

Certification options for the new version will be announced when the new standard is released. If you didn’t receive the notification, please contact us.
