The term performance assessment is used to describe any assessment procedure that involves either the observation of behavior in the real world or a stimulation of a real life activity. Performance assessment thus differ from traditional paper and pencil tests in the degree to which they represent or stimulate behavior in the real world.In this sense,any writing test that involves actual writing , as opposed to completing multiple-choice items, for example, can be considered a performance test, since the written product represent a performance of writing.
In a performance test in the strong sense of the term, language ability, and more specifically, language knowledge, in Bachman and Palmer's terms, may be only partly responsible for a successful task completion, and extra-linguistic factor may compensate for weaknesses in language knowledge.
In the weak sense of performance assessment, on the other hand, the focus of the assessment is on the language used, not on the fulfillment of the task. Tasks used to elicit language may resemble real-world writing tasks, but the purpose is to display language proficiency, not the ability to persuade or apologize. In other words, the readers who score the writing are interested more in the linguistic aspects of the writing than in whether they feel persuaded or ready to forgive the writer.
