Every Tuesday, we open up one lesson of the Dyslexia Trainer Certification Program here on the blog, all 48 of them, one week at a time. Whether you are a teacher, a parent, or an education professional, this series shows you exactly what certified dyslexia trainers learn, and how the program works from the inside.
This week: From Errors to Insights. Understanding Symptom Patterns through Error Analysis
Every error a child makes in reading or writing is a window into how their brain processes language. This lesson walks through the full process of error analysis: cataloging errors, recognizing patterns, and distinguishing structural, phonological, and orthographic error types. Trainers learn to link these patterns to visual, auditory, or memory-related challenges, and to turn everyday mistakes into a precise map for targeted support.
What this lesson is about
Every error a child makes in reading or writing is more than a “mistake”, it is a window into how the brain is processing language. By examining these errors closely, trainers can identify which areas of perception and processing require targeted support.

This lesson walks through the full process: from cataloging errors in the symptom area to analyzing patterns. Trainers will learn to distinguish between structural, phonological, and orthographic errors, and to recognize when these are linked to visual, auditory, or memory-related challenges.

Most importantly, error analysis is not about labeling a child as “weak” or “failing,” but about uncovering the reasons behind their struggles. This understanding can then be transformed into a training plan that restores confidence and builds essential literacy skills.
What you will learn in Lesson 6
- How to catalog reading and writing errors systematically
- Structural, phonological, and orthographic error types
- Linking error patterns to visual, auditory, and memory challenges
- Turning everyday mistakes into a targeted support plan
