A Worcester Park pre-nursery school has launched its latest effort to clear its name, following an Ofsted inspection report published last October that parents and staff said unfairly branded it inadequate.

Maria Churchill, manager of the Doris Venner preschool nursery, sent the education inspectorate a hefty report on January 29, cataloguing a series of complaints about the original inspection.

It also detailed complaints about a subsequent investigation in which Ofsted admitted a number of faults but upheld the original verdict.

A key passage of the Ofsted report criticised how new children were settled in after the inspector saw two Korean toddlers in a distressed state, but Ms Churchill claimed phone records obtained under the Freedom of Information Act showed the inspector could not have witnessed the whole incident.

Parents rallied around the nursery after the inspection report, which contained factual errors about the centre’s location and staff and student numbers, was published. Kingston Council described the facility as “good, with some outstanding elements”.

Ms Churchill criticised the investigation process, and said: “Ofsted did not interview the staff, talk to the parents or come to the site to make and informed judgement. There’s no one who will come in to look at the environment you work in. It is all done over the phone.”

She said the inspection was biased towards the inspector because only one-and-a-half pages of notes were taken of her 85-minute phone interview, while three-and-a-half pages of structured notes were taken of a 50-minute interview with the inspector.

She said: “That’s not all that I said in one hour and 25 minutes. There is a lot that is missing, so if someone else comes in and reads it they are not going to be come in and make a judgement.”

Ofsted told her they aimed to respond within 20 working days, but a spokesman said it did not comment on individual cases.

Explaining the outcome she was hoping for, Ms Churchill said: “We don’t want the judgement overturned. We want the judgement to be void and for someone to come back and do a proper, full and thorough Ofsted inspection observing activities and interviewing staff.”
