Phonological Awareness: Foundational, Critical, Yet Misunderstood

Phonological awareness is complex and often one of the most confusing components of the five essential elements of reading. Lack of success in phonological awareness affects progress in other essential reading components.

How does the 95 PASI work?

The 95 PASI helps you to understand where each child has skills they need to develop in phonological awareness. It follows the universal screening.

Screen each student using a ten-minute short form initially to determine which skills students have mastered.

Drill down within the readiness, syllable, onset-rime, or phoneme skills to determine which lesson to begin instruction.

Evaluate monthly to determine progress and instructional path.

The screeners are teacher-friendly, easy-to-give, and even more importantly, easy-to-interpret. Our teachers believe this form of ongoing progress monitoring truly gives them an accurate look at each child’s ability.
