Support for Students Who Need Help

Real-time alerts for swift interventions


Our Hotline system uses state-of-the-art artificial intelligence to scan every student response or note entered into our Test Delivery System to identify a response that is potentially a crisis alert that should be reviewed. Hotline detects at-risk text within minutes and sends an alert to human review for verification, providing for timely intervention.

ClearSight for Districts

Success made visible

ClearSight provides education leaders with research-based assessments that provide data to "take the temperature" of your district so you can make district-wide decisions on teaching and learning. Without assessments that align to specific state standards, teachers waste valuable class time that could be better spent on instruction. ClearSight provides reliable, valid assessments that generate timely data, allowing teachers to see results that are directly tied to their grade-level standards, informing their instruction to directly impact student success.
