National Board certification requires the submission of video recordings, which are scored by National Board Certified teachers hired to do so.
To be clear: there's a world of difference between the decades old National Board Certification and the new TPA. For example, we have serious concerns about the validity, reliability and appropriateness of the short, edited snippets of classroom instruction required under the TPA; National Board certification requires recording of entire class periods and prohibits editing. But that's all the more reason to conduct a pilot—so the field learns more about the strengths and weaknesses of this kind of assessment.
