The SP Performance Assessment section of LearningSpace provides a tool to evaluate how a certain SP performed in a learner encounter or through a whole Case. See: About SP Performance Assessment.
There are two main areas - and scores - which serve for this evaluation:
One of them is when an SP's answers to the questionnaires of the SP part of a Case are compared to the answers of an observer.
The other part of the evaluation is when an observer fills out a questionnaire (theSP performance assessment part) on how the SP performed in a certain encounter.
These two kinds of evaluation give the overall performance scoring of the SP.
