Greater utilization of certain Literacy by 3 classroom practices is associated with the increased likelihood of a campus exceeding district average growth in reading. Though the Literacy by 3 program has been in the Houston Independent School District (HISD) since the 2014-2015 school year, this study is the first to examine the relationship between Literacy by 3 practices and campus literacy growth in HISD. Specifically, this study aimed to identify which, if any, instructional practices contributed to literacy growth for a campus, by looking at the relationship between literacy practices in the classroom, student literacy practices at home, campus composition, and growth in literacy.
