Performance assessment involves observing and judging a student's demonstration of skills or competencies through tasks like creating a product, responding to a prompt, or giving a presentation. It emphasizes a student's ability to apply their knowledge and skills to produce their own work. Performance assessments typically require sustained effort over multiple days and involve explaining, justifying, and defending ideas. They rely on trained evaluators to score student work using pre-specified criteria and standards. While performance assessments integrate assessment with learning and provide formative feedback, they can be difficult to score reliably and require significant time from teachers and students.
