Assessment Engineering
Is assessment design art or science?
Assessment engineering submits there are
recurring structures and relationships we can
exploit
– in terms of language, data structures,
representational forms, and processes –
to enhance efficiency and validity in
assessment/task design.

Assessment Engineering
Idea not new or exclusive; some examples:

and psychometrics.

Assessment Arguments
What complex of knowledge, skills, or other
attributes should be assessed?
What behaviors or performances should
reveal those constructs?
What tasks or situations should elicit those
behaviors?

Too many notes?
As Emperor Joseph II said to Mozart.
Power in general/abstract representations,
» Reveals fundamental similaries under
assessments that look different on the surface.
» Right perspective for design of systems, but not
necessarily for work within systems.
Some people need to work from first
principles, but…
Scaling up for wide range of users requires
exemplars, support tools, tuned interfaces.
