Many thanks to everyone who answered!
I will follow @igazor 's advice and play until the next day to see if the child can go to school then. If he still can't, I'll try resetting or bulldozing the school.

One of the benefits of playing much longer age spans is that it there is usually still plenty of time to catch up when things like this happen though it did take a bit of work and effort on his part at the time. :)
I know! I usually play with aging either set to epic or turned off, but in this particular save (I normally cycle between seven or eight different saves) I wanted Sunset Valley to move a few generations ahead, and although I'm just playing one household, the fun is in observing the whole town. I'm enjoying "family tree surfing" - starting from one of my sims' family trees and clicking away to see how the whole town is interrelated. I used normal lifespan because I was impatient to get to the point when I can do that. It's like raising a miniature civilisation in a Petri dish. :)
