Oakfield Junior School was due to hold its Christmas show last Wednesday and Thursday but, despite informing Ofsted of their plans, they were told the visit would go ahead regardless.
Head teacher Rob Hart had to cancel the show, as the school would fail the inspection if there were no classes to assess, and children left the Bell Lane site in tears after the announcement last week.
"Coming to do an inspection at a primary school this late in the autumn says a lot about the chief inspector's attitude to schools," said Mr Hart.
"He doesn't seem terribly interested in the full child, just the academics and the data tests produce."
But despite a week already jam-packed with Christmas events, the school was able to reschedule the show for this Tuesday and Wednesday.
"It means that, on Friday when we break up for Christmas, I will be crawling," said Mr Hart.
"Cramming all that into one week will be a big ask. That's why we tried to spread it out over a week and a half and to give the children a weekend in between to recover from the school play.
"All that careful planning has flown out the window because of this but we will get everything done because the teachers are a dedicated bunch and we don't want the children to miss out on anything."
One parent, Colin Harris, of Cobham Road, wrote a letter to Ofsted to protest the decision, saying parents would have to rearrange or cancel childcare, dinner and lifts.
He wrote: "I would like some explanation as to what gives you the right to impose an inspection on Oakfield Junior School this week.
"Well done on making nearly 700 people in Fetcham very angry.
"As usual from any Government department I am not expecting any response to my rant apart from the pre-prepared statement you must have already waiting knowing what you have done to this community."
Ofsted spokeswoman Nadina Mustafa said: "Ofsted would not ask a school to cancel any planned event due to take place during an inspection. This would be a decision for the head teacher.
"Short-notice inspections were introduced to allow inspectors to see education provision in schools as it really is and reduce unnecessary planning or disruption for the staff before the inspection."
