The Downham Montessori Nursery was founded by its present owner, Mrs Laffeaty-Sharpe, in 1984. The Primary School was opened in an adjoining building 4 years later. Due to the increasing demand for places at the school, she moved both the school and the nursery to a larger property in Stow Bardolph.

In September 2009, Mrs Laffeaty-Sharpe opened the Downham Nursery School on Lynn Road, to meet the increased demand for nursery provision in the town.

In January 2025, a new classroom was built in the garden to provide additional places for 3 - 4 year olds.

The Principal and Proprietor is Mrs E Laffeaty-Sharpe. The school is registered with the DFEE and is affiliated to the East Anglian Montessori Association, the Pre-School Learning Alliance, and is a member of the LEA’s Early Years Development and Childcare Partnership (EYDCP).
