  Automated assessment has been shown to greatly simplify the process of
assessing students' programs. However, manual assessment still offers benefits
to both students and tutors. We introduce Gradeer, a hybrid assessment tool,
which allows tutors to leverage the advantages of both automated and manual
assessment. The tool features a modular design, allowing new grading
functionality to be added. Gradeer directly assists manual grading, by
automatically loading code inspectors, running students' programs, and allowing
grading to be stopped and resumed in place at a later time. We used Gradeer to
assess an end of year assignment for an introductory Java programming course,
and found that its hybrid approach offers several benefits.
