KeyPhonics Screening and Diagnostic Tool

Simplify the Assessment of Phonics Skills and Strengthen Reading Instruction Based on Actionable Data

CORE is a preferred training & support provider for KeyPhonicsFor decoding assessments to be most useful they must provide educators with the specific phonics patterns students have not mastered based on the phonics patterns that have been taught. This type of robust assessment data can be used to determine if further phonics diagnostics are needed, decide whether there is a need for phonemic awareness assessment, and provide targeted support to students who struggle with reading.

Together, KeyPhonics and CORE provide a comprehensive solution to your instructional needs in teaching and assessing phonics. KeyPhonics is an easy and efficient technology-based screener and diagnostic test for grades 1 and up. It measures the 12 most critical phonics patterns including 102 foundational phonics skills and provides comprehensive reports to help educators determine specific instructional and intervention needs at the student, class and grade levels.

CORE can help your team learn to administer the KeyPhonics screening and diagnostic measures, read and interpret the reports, make instructional and intervention decisions based on the data, and identify teacher professional support needs.
