The revised 2025 International Dyslexia Association (IDA) definition of dyslexia reflects decades of scientific progress. This edWebinar invites you to explore the full scope of this expanded definition. Dr. Tim Odegard, a member of the IDA definition committee, will bridge the gap between scientific language and classroom realities, and real-life experiences that persist across lifespans. He will clarify how this updated definition fosters a deeper understanding of dyslexia’s causes and defining characteristics.
Attendees will gain a deeper understanding of how a continued focus on instructional persistence informs our approach to identification and intervention. This session offers the reassurance that as our scientific understanding of dyslexia evolves, our shared commitment to helping every student thrive remains the heart of our work.
Learning objectives include:
- Analyze the core components of the 2025 IDA revised definition regarding word-reading accuracy and speed
- Evaluate “instructional persistence” as a key indicator of the dyslexia profile
- Identify the defining characteristics of dyslexia
This edWebinar will be of interest to K-12 teachers, school leaders, district leaders, dyslexia specialists, reading specialists, speech pathologists, and MTSS and intervention specialists.
