To help accommodate and accelerate learning for all, research was conducted to examine the unique properties of K–2 texts and how they affect the reading challenge for students. There is a wide variety of types of K–2 texts such as decodable texts, leveled readers and others that often have unique text characteristics.
For example, K–2 texts often have easy-to-decode words that become orthographically increasingly complex as texts become more challenging. Texts also incorporate certain types of systematic repetition and patterning that changes as the texts become more challenging. To help educators, content publishers and researchers better understand what characteristics are making a text more or less complex, the Lexile Analyzer was enhanced to identify the presence of the various features within text and report this information out as early-reading indicators in addition to the overall level of complexity (i.e., Lexile measure).
