PMP 35 Contact Hours / PDU Validity

PMP 35 Contact Hours And PDU

PMP PDU Validity

Here is the situation – a few years ago you took PMP 35 hours training and were contemplating on applying for the exam. But for some reasons you didn’t take the exam. Now you are confused about the validity of 35 hours of project management education. You getting bugged with questions like these:

  • What is the PMP 35 contact hours validity?
  • What is PDU validity period?
  • For how long is 35 hours training valid?
  • What is the PMP PDU validity?
  • Is there a time limit for 35 PDU training?
  • When do PMP PDU expire?

If you want answer to these questions then you are at the right place. I will answer these questions in this post. But some of these question are not entirely correct. There is a difference between PDU and 35 Contact Hours. Let us talk more about PDU and 35 hours of project management education. There are 2 different things:

  • PDU is an acronym for Professional Development Units – If you are a PMI certified professional, you need to collect PDUs during certification cycle. For example, you need to collect 60 PDU in 3 yearss to remain PMP certified.
  • 35 Contact Hours simply means 35 hours of project management education – If you are a certification then you do not need PDU. For example, you need 35 hours training to appear for PMP exam.

PMI PMP PDU Validity Period

The PDUs need to be acquired by a certified professional (e.g. PMP) after attaining the certification.  The PDUs are needed for Continuing Certification Requirements (CCR). A PMP certificate is valid for 3 years. To continue the certificate beyond 3 years, a PMP holder has to acquire 60 PDUs during the 3 years cycle.

The PDUs expire after 3 years. They have a validity within the Certification Cycle.

For more information you can refer to CCR Handbook available on

PMP 35 Contact Hours Validity

Most PMP aspirants choose to use the term “PDU” instead of “Contact Hours”. Usually, they have been mislead by the training companies. Many training make false claims that they provide 35 PDU. They, instead provide PMP 35 hours training. The 35 hours are required to meet the mandatory requirements for appearing in the PMP Exam.

The 35 Contact Hours do not expire. They have a lifelong validity.

The 35 hours of education can also be used as 35 PDUs for CCR, but only after you become PMP certified. For more information you can refer to PMP Handbook available on

    • Hi Aarthi, There is no need to change once application has been approved. Only if there is an Audit and only if they ask for confirmation of contact hours then you can provide explanation.

      All the best.

  1. Hi,

    I wanted to check about the 35 contact hour validity.
    I have obtained 35 contact hours in PMI accredited training in 2013 and previously in 2011 through my previous organizations but the certification was not a priority or business need for me then.

    However I wish to appear for the certification soon and was planning to self study. Like you accurately deciphered, several training providers said that contact hours obtained >3 years ago will not suffice the entrance, ergo i should enroll with theml Your comment that 35 contact hours do not expire has been a relief from that aspect. :)

    From the view of exercising further caution, can you please provide any PMI reference which says this (hours not expiring)? Just as a safe side. Thank you!

    PS: I already checked the latest handbook unsuccessfully.


    • Hi Naren,

      There is no reference on PMI website that categorically says 35 contact hours do not expire; at least I did not not find any. But at the same time PMI does not say 35 contact hours expire. Before writing the article, I had called the PMI customer care to verify this. You can also call them.

      Secondly, your 2013 training may be based on PMBOK 4th ed. content. So, you may want to attend a new training. Otherwise, also it is beneficial to attend the training again. There is a cheap way to do training –

      Good luck.
