I did a quick look to search to see - I mean if anywhere has retained evidence of schools it should be Pompeii - I did a cursory search through Bloomer's book 'The School of Rome', and here are some bits from it: "The physical requirements for a grammar school were minimal: school, like any small ancient business, could be held on the street, under or above a portico, near an important public building such as a temple, or at a rented shop. A wall painting from Pompeii, now lost, showed school near a portico and decidedly amid the bustle of the city. School could be held “in private,” at the teacher’s home or the house of the patron." "Graffiti indicate schooling took place at several locations in Pompeii and at Rome. The places of instruction are unremarkable shop stalls. Two exceptions to these modest locales merit attention, since they seem to have dedicated space and indicate an education that is decidedly not modest. The emperor’s palace had a slave-training complex known as the paidagogia , and the villas of the wealthy had as part of their design semicircular recesses, or exedrae. The latter, like private libraries, are places of culture, perhaps of poetry reading or rhetorical training." (It links to footnotes which reference an Italian paper apparently saying there are disputes as to how to recognise schools as such). Anyway, yeah, very good point!
