READ 180 is a reading intervention program in wide use by students in Grades 4–12 who read at least two years below grade level. READ 180 is based on a blended instructional model that includes whole-group instruction and three small-group rotations, adaptive software, differentiated instruction, and independent reading. The program has three different versions: Upper Elementary (Grades 4–5), Middle School (Grades 6-8), and High School (Grades 9–12).
