Nadder Church of England Middle School, Tisbury

The Church of England school remained an all age school, with children up to 15 years old, until 1961 when the Dunworth Secondary Modern School was built at a cost of £115,766. Children from 11 years and upwards started at the school in September 1961 and the school was officially opened on 30th May 1962. The school leaving age was raised to 16 in 1965 and in the 1960s Dunworth had a farm unit for studying agriculture and livestock rearing as part of the county council's policy for schools in rural areas.

The three tier system of education was introduced into Tisbury in 1983 and Dunworth became the Nadder Church of England Middle School, taking pupils aged from 9 to 13 years. Older pupils continued their education at Shaftesbury Upper School. The school has a wide rural catchment area of five local first schools with buses bringing in children from the surrounding villages. By 2002 there were 155 pupils at the school.

In 2003 Tisbury is preparing to change back to the standard two tier system and the school will close in July 2004. Pupils will remain in St. John's Primary School, at present the first school, until the age of 11, when they will travel to Shaftesbury for their secondary education.
