PARCC's Mathematics Performance Level Descriptors (PLDs) describe performance expectations for the four assessment sub-claims:
- major content
- additional and supporting content
What differentiates current PLDs from those in the past is that current PLDs were developed in consideration of both mathematical content and mathematical practice standards. Mathematics PLDs were developed with careful attention to cognitive complexity and are available by grade band.
