What is the most important selection criterion for core instructional materials in beginning-reading skills?

The most important selection criterion for core instructional materials in beginning-reading skills is aligning with relevant state learning standards. This is because state learning standards provide a framework that outlines the specific skills and knowledge students are expected to acquire at each grade level. Selecting materials that align with these standards ensures that instruction is focused, coherent, and relevant to the educational goals set by the state. This alignment helps educators provide a structured approach that leads to effective learning outcomes for students, allowing them to progress in their reading skills in a manner that is consistent with established expectations.

In the context of beginning-reading instruction, materials that align with state standards will typically incorporate essential components of reading, such as phonemic awareness, phonics, fluency, vocabulary, and comprehension, thereby providing a comprehensive foundation for young learners. Additionally, aligning with state learning standards can help prepare students for assessments and other benchmarks that they will encounter in their educational journey.
