Evaluation by J Payne of SCAU on the second of three phases of development revealed a single linear ditch of probable post-medieval date that may equate to a field boundary shown on the c1840 tithe map.

Evaluation by T Collie of SCAU. The results show prehistoric and/or medieval or early post-medieval activity across the area. Most of the features were identified in trenches located across the western half of the southern field, and they include a number of substantial ditches of probable medieval or early post-medieval date.
Evaluation by W Weller of SCAU revealed no archaeological features. Some finds were recovered from the subsoil and spoil heaps including a small amount of struck flint and post-medieval/modern ceramics.
Watching brief by W Weller of SCAU showed the site to have been severely disturbed. However, a large ditch of probable Roman date was observed close to the main school building and is possibly a continuation of ditches excavated by S S Frere in 1939 and 1940 (SyAC 48, 45–60). A compacted chalk layer, which may represent a courtyard area between buildings noted on the Ewell Enclosure Map of 1803, was also recorded. A quantity of worked flint of Mesolithic, Neolithic and later Bronze Age date was recovered, indicating activity during these periods within the vicinity.
Evaluation by J Payne of SCAU identified an undisturbed subsoil horizon across the south and west of the site, a post-medieval wall foundation and two probable postholes of medieval date.
Evaluation by W Weller of SCAU revealed a small posthole of indeterminate date and some 20th century disturbance and formation layers associated with the recently closed A3 road. No archaeological finds or features were observed.
Watching brief by M Saywood of SCAU did not reveal any archaeological finds or features.
A watching brief by M Saywood of SCAU on an area in the northern limit of the main quarry overlying the Gault clay revealed no finds or features of archaeological interest.
Excavations by J Payne of SCAU ahead of planned mineral extraction revealed evidence of archaeological activity dating from the Mesolithic through to the post-medieval period. The more important finds included a pit that contained Beaker-type ceramics, diagnostic flint tools of Neolithic and Early Bronze Age date and the remnants of a Middle/Late Bronze Age field system, which was in part truncated by a Middle/Late Iron Age settlement. The Iron Age settlement comprised a series of ring-ditches and numerous discrete cut features set within a substantial enclosure ditch.
Archaeological monitoring by T Collie of SCAU revealed no finds or features of archaeological interest.
