Decoding (D) x Language Comprehension (LC) = Reading Comprehension (RC)
The Simple View formula and supporting studies show that a student’s reading comprehension (RC) score can be predicted if decoding (D) skills and language comprehension (LC) abilities are known. Notice that D and LC are not added together to predict RC. They are multiplied. In the Simple View formula, the values of D and LC must be between 0 and 1 (or 0% and 100%). A score of 0 means no skill or ability at all and 1 indicates perfection.
