This chapter extends the discussion of timing-related issues to an area that has received considerably less attention in the literature: performance assessment. It discusses the published literature that does exist in this area; this work mainly relates to writing tasks. The chapter addresses timing considerations in the context of other types of performance assessments and report on a previously unpublished experiment examining timing with respect to performance on computer-based case simulations that are used in physician licensure. S. Pohl, E. Ulitzsch, and M. von Davier and Pohl and von Davier describe an approach that combines timing information with data about what part of the assessment was not reached by the examinee. This approach can be useful when looking at process data in complex performance items where respondents are not expected to reach all parts of the assessment. Examinees were also administered a questionnaire to gather information about their self-perception related to their ability to write quickly.
