Suppose a class in 7th grade ends with an average Math Growth RIT score of 240, and we want to set the goal for that class in Math, but for 8th grade.
The norm for 8th grade is 231. Intuitively, it seems that setting 231 as a class goal (which is already at 240) is not beneficial. Is it reasonable to use the expected growth of a year (i.e. 5 points) and add them to the end of the year average RIT (240) to set the goal for the next year (240+5 = 245)?
