Not all have
a valuable role
in assessment:

there are levels
of granularity;

there is
derivation of
component level
rather than
script level;

there is
quality of marking
as
marked items;

there is
ideal quality of
at the least
granular marking.

Where metrics is
non-trivial

this is
derivation of
component level metrics.

In such instances
ex
ternally
assessed examinations

present the idea of
marking consistency

as variable.
