Has anyone recently been given an extension on their CA teaching credential? I have to apply and am nervous and still confused about one aspect. I am going for the 2-year extension. All the information specific to the 2-year extension says that all I need is the application, form CL-885, and the fee. However there are other places on the CTC website that say that ALL extension applications must include a letter/statement showing good cause for the extension. Other types of extensions do list the letter/statement as a requirement, however the 2-year one does not. But again, there is that occasional paragraph here or there that says all applications must have it. I am concerned that I may not be able to show good cause. Does anyone have experience with this?
