So I did a little surveying on social media to find out what others have done in this situation. I have a few responses that I would like to share with you. (Thank you to all the fine people who responded. I hope you don't mind me sharing your name on here. I wanted to make sure you got the credit for your input. Thanks)

On the CTC website there is an option to have them send you a certificate version of your credential, which you can print out and take to a notary. However, on the certificate is says "not an official document." So, what I usually do to be safe is print both that certificate as well as the printed web page of the "live" credential on the CTC teacher look-up website then take that to notary, then take the notarized documents to State Department building in DTLA and have them validate the notary. Not sure if that second step is needed for Mexico, but it is for China and Vietnam

My original certification is from California too and when I moved to Arizona I printed the page

From the website and had it notarized.

You can ask the CTC for a letter confirming your cetification. For vietnam i notarized and apostillid the letter and the screen shots off the CTC lookup. It worked fine.
