Real Time Dashboards
All stakeholders can easily access the data they need. Live dashboards provide accurate, up-to-the-minute tracking of student development and provide administrators with snapshots of how children, classrooms, and centers are performing in real-time. Teachers can easily view unassessed items, as well as the items in which children need the most support, guiding lesson planning, and scaffolding.
Robust Reporting
Administrators and teachers can analyze child, classroo, or program-level data based on the COR Advantage indicators. The reporting suite includes tables and charts to show performance, growth, and completion data. Use the reports to track development over time, identify strengths and areas for growth, and analyze how children are progressing toward Kindergarten-readiness standards. Customize reports by easily filtering by demographic information such as funding source, age, or race.
Inter-Rater Reliability
The free inter-rater reliability process ensures all teachers can enter accurate, valid, and reliable data that administrators can trust for reporting purposes. All teachers who pass the test with at least 80% proficiency will receive certification valid for 3 years.
