Summary: The Longitudinal DIBELS Results for PreK Cohorts report provides a multi-year view of early literacy performance for students beginning in Pre-Kindergarten and progressing through elementary grades.
Usage: This report helps district and campus leaders:
- Support MTSS, intervention planning, and instructional decision-making
- Monitor reading readiness trends over time
- Evaluate the impact of early literacy instruction
- Identify cohort-level strengths and intervention needs
By tracking the same student cohorts year to year, the report moves beyond a single snapshot and instead tells the story of literacy growth.
