(Advantage -TASA Open Standard) Readability Formula for Books is the new
readability formula developed by Renaissance. Designed by a team
of leading readability experts, ATOS eliminates many of the problems educators
have always had with existing readability formulas. ATOS is the first formula
to include statistics from actual student book-reading (over 30,000 students,
reading almost 1,000,000 books); not just data based on short text passages.
improves readability scoring of several types of books where previous formulas
have been less accurate and less helpful to teachers. Because ATOS provides
higher readability scores for longer books, it intrinsically encourages
students to choose longer books because the Renaissance Accelerated Reader point values are
now higher, reflecting the fact that their length makes them more difficult to
read. ATOS also takes into account the differences between fiction and
non-fiction. It more accurately levels low-level books, whether they are aimed
at high-low or emergent readers. The result of all these improvements is less
guesswork from both teacher and student. Better matching of books to students
with ATOS will help teachers keep students in their appropriate reading range
(zone of proximal development, referred to as ZPD), and thereby accelerate growth in student
reading ability and learning.
