I am so glad you asked! There are actually a couple of ways to get to your IPDP.
Here is the 1st way. Just Click on Learning Plan to find pending and approved requests... including your current IPDP.
Here is the 2nd way to find your IPDP. As you can see, this way lets you access previous and current IPDPs. Remember how we have to register online for our district PDs? This is where you can find those certificates to submit.
