I'd stop looking....it doesn't exist. I'd bet the house on there being no article to back-up "The district where I live has 11 schools in it. That same district has 9 superintendents, and 9 assistant superintendents.", either. Pretty confident that post-grad work wasn't in mathematics. If you're going to make stuff up at least try to keep it semi-believable.

Oh, btw, simply let us know the school districts you're referencing and we can look it up ourselves. I'm sure all 9 superintendents will be listed on the district website along with the 28,106.1 administrative employees (11 schools * 150.3 students (average school size in US) * 17 admin employees per student). Yeah, those teachers are the "truly dumb" ones.
