Phonics assessment designed to inform instruction

Science of Reading research proves that mastering phonics skills is critical for students learning to read. Knowing how well students are developing phonics skills gives teachers the insight they need to guide phonics instruction in grades 1–6, and for students who are struggling at any grade level.


Measure understanding of the 12 most critical phonics categories and 102 target skills.


Intervene knowing exactly where a student is struggling.


Know which patterns to teach individuals, small groups, grades, and classes.


Align results to the scope and sequence of your reading curriculum to gauge progress and needs.

I recommend Star Phonics, which is based on years of research, because it is the best phonics screener and diagnostic assessment available.
