If I recall correctly, Pemberley's DD is in a special ed school, paid for by the public school district.
The TEMA is a decent instrument, for what it's intended (which is exactly what the name suggests--early math skills). If used with children over age 8, one would have to use the age/grade-equivalent scores, rather than the standard scores, which is not an unusual practice in severe needs contexts. Pretty much any special ed teacher or psych can administer it (it's only a B-level instrument), but there is value in having a math specialist do so, (preferably a dually-certified math/special ed teacher) to capture maximum clinical information.
In answer to a much earlier question: there may already be sufficient documentation for a calculator, (depending on your state/local regs) in the form of the very low math fluency score, and the absence of multiplication facts in an HG+ child of this age. I would say her uniform slide in math achievement scores from year to year indicates that she is making negligible absolute gains in math skills (hence the lower standard scores), just as her peers are about to take off, having mastered arithmetic facts. If not remediated, I would expect the gap to be even bigger in another year.
And yes, Dr. Mazzocco is a big name in dyscalculia.
