Canadian researchers2 found that classroom observations by visiting auditors fail to touch the real day-today experiences of children and their teachers. In one school in our 1995 study students warned us to be wary of using impressions of visitors as a source of evidence. They said they had become very well trained on how to show the school off to its best for outsiders and inspectors. One student described the school as ‘a Jekyll and Hyde school with two faces. It has one face for visitors and one for us.’
