These tools aim to support teachers in helping young readers do deeper reading work in the books they are reading—and help them move up levels of text complexity. There is no one researcher whose work is the foundation for these documents. They reflect thousands of hours spent in classrooms, reading texts alongside young readers, coaching readers to deepen their reading practices and move up levels of complexity. We hope that they support you in your conferring and small group work. Many thanks to the teachers, researchers, and educators who helped frame these tools. They include: A Tool for Supporting Readers Moving Up Levels, Bands of Text Complexity Cards (for teachers and students), and Benchmark Independent Reading Levels.
