Our little Goldsboro school had two classrooms. When i started school, those two classrooms contained 6 grades. Yep, 3 grades and 1 teacher in each classroom. We did not have kindergarten. Sometime before i attended the school, it contained all 12 grades.
Yet from this humble little school came some well educated, successful people. From my contemporaries, say those of us born from 1946 to 1950, there are doctors, lawyers, a university president, a world renowned nuclear engineer and a vice president of engineering. Most of us are retired now.
One cool feature of the building was that the two classrooms were separated by a collapsible, floor to ceiling partition. I can only remember it being open once for a Christmas program. I think it was labor intensive to open it.
