Unlike the Smarter Balanced assessments, CAST is administered at select grades, offering unique insights into students’ science learning. This resource highlights proactive steps that administrators, school leaders, assessment coordinators, and data analysts can take now to leverage CAST data effectively, ensuring readiness for this significant change in accountability reporting.
