How does the Colorado Growth Model account for demographic or regional differences among students in its calculations?
The Colorado Growth Model does not account for any demographic or context variables in the calculation phase itself. The calculations do not even know what school or district each student is in! The algorithms used only know students grades in a set of calendar years and what scores they earned on CSAP in those years. When growth data are reported for groups of students, the individual growth scores are grouped after the growth calculations have been performed. No adjustments are made to the calculations on the basis of any demographic or other group, so that all students are treated equally by the model.
