Steps in Developing a Performance Assessment

1. Define the performance

2. Determine the most appropriate form for the assessment scale

3. Create a scale to represent your criteria

* primary traits (i.e., a series of scores relating to each component of the performance)

* narrative (i.e., anecdotal feedback relating to salient aspects of the performance)
 communicate assessment criteria with participants, and/or have the participants take part in the development of the criteria.

4. Prepare for sampling and technical considerations

¨ How much of student's work is necessary to represent the whole?
¨ How many students out of the whole?
¨ How can the procedure best be carried out efficiently?

5. Address issues of reliability

Problems addressed description solution
inter-rater reliability · different scores for the same level of performance from different raters · common criteria
· practice rating together
· anchor papers/performances
intra-rater reliability · different ratings given to performances that are similar · experience
· awareness of biases
· sample effectively
scaling reliability · too much or too little variation in the scores.
· all too high or too low · anchor papers (papers that have been chosen to define each level of performance)
performance reliability · ratings may be consistent, but do not fit with what performers were trying to do. · common understanding between raters and participants
· Well-defined criteria
· use of student self-assessment
