In fact, the Scottish Office need have looked no further than Tom Bone's history of the Inspectorate to learn. HMI's annual report for 1847 stated that of 104 teachers examined 43 had been to university and only three or four had been recruited from other jobs. "There are no decayed tradesmen or disabled labourers among them."
None the less a quarter were, "from age and infirmity, unequal to the duties of their office". Small wonder the EIS was founded to promote "sound learning", or was it to protect members from overzealous Government comment on incompetent teachers?
