A trial trench evaluation was carried by Archaeological Project Services in January 2009, in the grounds of the former Quarrington Primary School, Grantham Road, Sleaford. Two trenches were excavated - the first located to the north of the extant buildings and measuring 15m by 1.6m wide, the second located to the south and measuring 21m x 1.6m. Undated ridge and furrow was located in the second trench. {1}{2}
