Breakthrough Results in Sound Processing

Recent results from a randomized controlled trial of NOW! Programs have revealed significant gains for students who process language differently. After just 60 to 65 hours of targeted speech-to-print instruction, students demonstrated a mean gain of 28.6 percentile points in phonological processing, specifically in the area of elision—the ability to remove and manipulate sounds within words.

This study is particularly noteworthy because it focused on students navigating significant reading challenges. The results showed an effect size of 1.8, a statistically massive leap that suggests the instruction method is hitting the mark for the root causes of reading struggles. Half of the students involved in the study gained at least 30 percentile points, proving that the right input can trigger rapid development.
