Support foundational skills development with real-time insights that improve student outcomes and ensure student readiness.


K-12 Assessments
Our assessment portfolio provides educators with invaluable insights to inform personalized instruction, equitably place students and identify gaps in student potential and performance.

Identify learning gaps early.
With ESGI, teachers can easily collect, track, and analyze student data to understand if students have fallen behind.
Administrators have real-time, district-wide visibility into where students stand. When early learner data is simple to gather and analyze, districts can identify learning gaps and intervene before they interfere with students’ trajectory toward 3rd grade readiness.

Identify Developmental Delays Early and Confidently.
With the Battelle® Developmental Inventory, Third Edition (BDI-3®), assess what matters most for early learning—and take action before delays become barriers.
BDI-3 is a comprehensive, research-based tool for identifying developmental delays in children from birth through age 7 years, 11 months. Aligned with IDEA, it assesses key domains—like communication, motor, and social-emotional skills—to support early referrals and intervention planning.
