The four criteria for assessing class importance apply to enclosed cremation cemeteries as follows:
- Period (currency): Extended. Present evidence suggests that the tradition of building and using enclosed cremation cemeteries spanned much of the late Neolithic period, perhaps as much as four or five centuries.
- Rarity: Very rare. Only three fairly certain enclosed cremation cemeteries are known in England at present and even though this undoubtedly represents an underestimate of what was once present it is unlikely that the class as a whole was ever very numerous.
- Diversity (form): Low. Only one type of enclosed cremation cemetery can be recognized among known examples, although it is clear that a fairly wide range of sizes is present.
- Period (representativity): High. Enclosed cremation cemeteries are one of a fairly restricted range of monuments relating to the late Neolithic period; they contain evidence for a fairly widespread burial rite of the period.
Assigning scores to these criteria following the system set out in the Monument Evaluation Manual, enclosed cremation cemeteries yield a Class Importance Value of 35. This lies just over half-way up the range of possible values (max.= 64) reflecting the great rarity but essential homogeneity of enclosed cremation cemeteries. Examples representing the observed variations in size and orientation must be included in the sample of nationally important sites, although given the very few examples known it is possible that choice may be limited by what survives.
