What is "text complexity"?

Text complexity refers to a measure of a text's difficulty based on various factors, which can include vocabulary, sentence structure, themes, and the knowledge required for comprehension. This multidimensional approach considers not only the linguistic features of the text but also the cognitive demands placed on the reader. Recognizing text complexity is crucial for educators and reading specialists because it helps them to select appropriate reading materials that match students' reading abilities and engage them effectively.

In educational contexts, understanding text complexity allows practitioners to scaffold instruction and assess students’ reading levels more accurately. It emphasizes that reading comprehension is influenced not just by the text itself, but also by the reader’s background knowledge, experiences, and skills. This understanding ultimately guides instruction and helps in developing strategies to support readers in tackling more challenging texts as they progress.
