DC CAPE math continues DC’s PARCC-era alignment to the Common Core State Standards and uses the same general development/review approach described by OSSE. The page says DC Math follows the same rigorous development and review process and measures the knowledge and skills that matter most for DC students, while also explicitly tying the assessments to CCSS.
DC CAPE Geometry math practice. Domain by domain.
DC CAPE Geometry math practice organized by the test's 6 official reporting domains. Together they connect 19 playable math skills to Common Core State Standards (CCSS-M).
