I recommend Star Phonics, which is based on years of research, because it is the best phonics screener and diagnostic assessment available. It provides valuable information about phonics skills essential for instruction, especially for those students struggling to read words, including students with dyslexia.

The Star Phonics online assessment helped our teachers to quickly pinpoint the areas of weaknesses in phonics for their students. The easy-to-administer screener and diagnostic assessments are valuable tools for elementary teachers. The resulting data, presented in high-quality reports, assisted teachers in their decision making for their small group instruction in foundational literacy skills.
