Ah, I don't know about that. A 10-year-old that knows and uses jargonese such as "numbering" and "rubric" and "ensuring" and "nervous" in extended adult phrasing seem to me as if she might have been well-coached to deliver lines that ought to have been delivered by a mature education professional. Hmmmmm. I smell a rat here, the use of a child as a publicity-getting trick to present a mature argument.
I think it's a cheap scheme to try to get the general audience to think that judicious testing of the knowledge advancement of a pool of students is not a good way to assess the effectiveness of their teachers, and the local applied educational philosophy as well.
The schemer ought to be brought out from behind the screen and examined for perpetrating his/her concepts through a pliant child.
