In a performance assessment based on a case study, how can a teacher ensure accurate results before students begin?

Providing students with information about evaluation criteria is essential for ensuring accurate results in a performance assessment. When students understand the specific standards and expectations against which their work will be assessed, they are better equipped to focus their efforts accordingly. This transparency reduces ambiguity and allows students to align their responses with what is necessary for success, thus fostering a more accurate demonstration of their understanding and skills.

Clear evaluation criteria help set specific performance expectations, enabling students to self-assess and revise their work in accordance with the standards. When students are aware of what evaluators will be looking for—such as clarity of thought, the depth of analysis, or application of concepts—they can better tailor their efforts to meet those expectations, ultimately leading to more valid and reliable results in the assessment process.
