When somebody askes you, “What’s the Science of Reading?” what do you say? Is it a process? Is it a set of strategies? An approach or method? A reading program? A group or organization? In this chapter, I will attempt to define the Science of Reading. And notice that I’m using capital letters. This enables us to differentiate between a science of reading as one of several sciences of reading and the Science of Reading as a proper noun or title,

The Science of Reading seems to refer to a general consensus related to the strategies and practices that lead to improved reading outcomes. These strategies and practices have been determined to be effective using experimental or quasi-experimental research and conducted in authentic learning environments. Also, this research has established a causal link between strategies or practices and student outcomes (reading achievement). Thus, the Science of Reading can be thought of as a process that uses the standards in Figure 16.2 when making decisions related to reading instruction and policy. However, the SoR might best be described today as a self-defined movement that advocates these standards be used for making decisions related to reading policy and instruction.
