Just give them the numbers. Are educators really incapable of understanding this? It's just not that complicated.
For a fun exercise, attend one of those meetings with an army of school staff, use the phrase "standard deviation," and count the pairs of glazed eyeballs.
And, what Minx said.
I have done this--more often than probably desirable, considering they are my colleagues! Actually, I have toned it down over the years, to reduce the numbers of parent eyeballs that also glaze over, and also because my more important objective is to have everyone present understand the results well enough to provide appropriate instructional settings and supports to the student.
