Drawing on the spring 2023 American Instructional Resources Survey, the authors examine teachers' use of foundational reading activities in their instruction. These activities correspond to the four foundational reading skill domains for kindergarten-through-grade-5 students that are set forth in the Common Score of State Standards: print concepts, phonological awareness, phonics and word recognition, and fluency. The authors compare teacher responses by grades taught, characteristics of their schools and classrooms (e.g., students' race or ethnicity, English language proficiency, disability status), and state policy context.
