This answer is two-fold:
CERT offers three levels of analytics, from the most granular standards included in the Career and College Readiness Standards to the most general. This means that teachers who use CERT have unprecedented access to the data they need to offer differentiated instruction that is tailored to group and/or individual strengths and weaknesses.
CERT offers a high-level view of CRS performance to help teachers diagnose curricular gaps and discrepancies, allowing schools to make meaningful, real-time modifications to curriculum and instruction.
