What constitutes the level of achievement in a task?
You can decide on the standards for your assessment task by:
- consulting a taxonomy, such as Bloom’s or SOLO, to get clear about performance progression. The Australian Qualifications Framework (AQF) standard descriptors are also useful to consult.
- collecting student samples and looking for themes in performance and ability.
- taking or adapting words and phrases from other well-written rubrics for assessments of a similar nature.
Various standard scales exist; they typically range from 2 to 5 point scales, whereby a 2 point scale is a binary scale of competent and not yet competent.
When choosing a standard other than Monash’s (HD, D, C, P, N), it is necessary to have clear overall definitions of each standard with descriptors for each criteria. It is also important to map them back to Monash’s standards. There should be a clear justification for using a particular set of standards, such as if one already exists in a particular industry or that the unit is competency-based.
It is also important to consider what understanding students and markers have of your chosen standards. Within a course, having units and assessments that vary in terms of expectations for ‘competence’ can cause confusion and limit students’ understanding of what constitutes a quality task. A collective set of standards helps to maintain consistency across tasks, units, and courses. The HD, D, C, P, and N labels are well known, so they are a good place to start when designing a rubric.
