LSE marking normally requires double-marking or moderation, and sharing examples with the external examiner. This may be harder to achieve with in-class participation. For moderation, a colleague can sit in on a proportion of classes. If participation is a component with a lower weighting, then single marking may be possible.
For a large cohort where multiple class teachers are marking, hold a moderation discussion in advance to discuss the rubric.
Templates are available in this resource that illustrate the range of ways in which you can assess participation. Consider how the marks will be moderated (can the course convenor sit in on one session with each tutor?) and how the external examiner will be able to evaluate the assessment process.
In-class participation is relatively low-risk for academic misconduct but students may read from pre-prepared notes, or use generative AI during in-class discussions.
