Most of the flint appears to derive from locally sourced flint nodules that naturally occur in geological deposits surrounding the school site. Even though the assemblage demonstrates that locally sourced raw material was exploited in the area, no in situ knapping deposits survived on site. The type and quality of flint that was selected for use is variable and includes black semi-translucent flint, grey semi-translucent flint and opaque types, along with Bullhead flint (flint with an orange band below an outer coat stained green by the overlying deposits of sand). The majority of the late Neolithic flint assemblage was recovered as residual finds from later prehistoric features, however it is possible that particularly shallow Neolithic features might have existed within the site, but were lost to truncation. Two pits may be an exception as each produced a sizeable assemblage of struck flint of characteristically late Neolithic date. It is possible that the presence of Neolithic flintwork within later pits represents a more substantial deposit, possibly a midden or refuse dump, which became dispersed and then, potentially, deliberately redeposited in later features. It was notable that sherds of Neolithic pottery, whilst fragmented, were in good condition suggesting they may have remained undisturbed in a midden deposit until redeposited, along with struck flints, in later pits. Analysis of the flint assemblage suggests the polished axes were probably manufactured elsewhere and brought to the site in a finished state, hence a raw material source further afield is likely. The same may be true for some of the high-quality black flint pieces that include a scale-flaked knife and a scraper. Archaeological works at the Ellington School site were divided into four areas. The considerable assemblage of residual struck flint was recovered from across the site with the majority of the flint assemblage collected from Areas 3 and 4. A small number of potentially early Neolithic flint artefacts (axes and an arrowhead) were also represented. The flint assemblage was largely recovered from features dated to the middle and late Bronze Age/early Iron Age and from mechanically removed layers of overburden. A significant proportion (approximately 1,100 pieces) of the flint assemblage was recovered from just six features of earliest Iron Age date (800–600 BC). Therefore the assemblage is mostly residual, however it is possible that some of the flint implements, such as the polished axes, were deliberately placed artefacts. The assemblage included a very fine leaf-shaped arrowhead located at the base of a large, metalled hollow-way, a number of faceted flint hammerstones recovered as residual finds from features of a later date, and two polished axes, other finished implements and a large quantity of struck flakes recovered from the basal fill of a pit. A small assemblage of residual late Neolithic pottery was also recovered from the site. Although the excavation identified very little, if any, structural evidence of Neolithic settlement anywhere on the site, activity and probable occupation in the area is clearly represented by the considerable assemblage of later Neolithic flintwork recovered during the excavation of later features and during the initial machine stripping of the site.
