This talk discusses the nature of mathematical assessment, and
compares paper-based learning materials with current online assessments.
In the light of this comparison we report on the implementation of a data
structure for representing multi-part mathematical questions, which form
part of the new version of the STACK system. STACK makes use of the
computer algebra system Maxima for a variety of tasks, the most important
of which is establishing mathematical properties of student's answers.
The key difficulty is of increasing the richness of the question types so
that they better reflect the needs of question authors without increasing
the complexity to a point where they become effectively impossible to
