ABSTRACT
Because the rate level of an individual is purported to be a very important cause of high and low reading achievement, it is important to determine what can be done to improve RL. In the causal model, it is theorized that the two proximal causes of improvement in rate level are pronunciation level and cognitive speed level. This means that the two factors that influence gain in RL during a school year are the gain in PL and the gain in Cs.
