There's no hope for this. Random checking shows that the vast majority
of middle school articles are essentially catalog entries. When the
private schools are excluded, there isn't a one I've found that shows
the slightest hint of notability.
But we'll never be able to get rid of them. If we try, there will be a
tremendous outcry, and the indiscriminate inclusionists will appear to
support those whose editing ox is offered up for sacrifice. Perhaps
there is some hope for a blanket statement that schools under the high
school level are not intrinsically notable. Heck, I'd like to do that
for high schools too, but it won't happen. But as it stands, the
disambig page for all the "Martin Luther King, Jr." schools is going
to be huge, because the direction is at the moment that all of them
will eventually get articles.
