A Lexile Measure is a standard used to evaluate the reading ability of individuals and the difficulty of texts. It is expressed as a number followed by an "L" (e.g., 850L), indicating the level of reading comprehension required. This measure helps educators match students with appropriate reading materials that suit their skill levels, promoting effective learning. The Lexile Framework considers factors such as vocabulary and sentence length to determine a text's complexity. By using Lexile Measures, teachers and parents can better support a child's reading development and ensure they are challenged without becoming frustrated, ultimately fostering a love for reading.
