Performance assessments can be defined as those tasks that require students to demonstrate their synthesized knowledge, understanding, and skills by addressing several objectives, sometimes across multiple disciplines, all without teacher assistance.
3-Rubrics allow the teacher to clearly articulate their expectations, while providing students with clear understanding of what is required to meet and extend beyond particular performance standards.
Teachers can gather a demonstration of the knowledge a student has on a subject rather than simply testing the accuracy of their response on a selection of questions.
Performance based assessments allow students opportunities to use learn how to ask questions, to organize data, to compute, and to write. Ultimately they learn to apply these skills in meaningful ways.
Challenge 2: Content There is also an inherent trade off between time and content; the more content the performance-based assessments attempts to cover, the more time it will take to design, administer, and score
Challenge 3: Reliability The main threat to reliability comes from the necessity of having ‘experts’ score the performance-based assessment. Even with a rubric, there may be variation in scoring.
Challenge 5: Cost Performance-based assessments are usually the most costly approach due to the amount of time required to train raters, as well as score the assessments.
