Performance test (bar exam)
The performance test or "PT" is a section of the bar exam that is intended to mimic a real-life legal task that future lawyers may face. Of the three parts of most states' bar exams -- MBE, essay, and PT—the PT is probably the most reflective of how well a candidate will perform outside of an academic setting.
A performance test may include tasks such as writing a legal memorandum, drafting an affidavit, or drafting a settlement offer letter to opposing counsel.
Performance testing as part of a technical specification is covered on a different page.
