Definition of Reading Intervention. Reading intervention is a program, supplementary to an existing literacy curriculum, that is provided to students for the primary purpose of increasing reading levels. Such programs can be administered both in and out of the traditional classroom environment.
The Accelerated Reader program is a computerized program that tests reading comprehension. Students select books on their reading level, read independently, and take an independent comprehension test on the computer. Each book is worth a certain number of points based on its length and reading level. Students get a percentage of these points based on how many of the test questions they get right. The program tracks their progress over the course of the school year.
