Teacher Group District-wide
Assign points based on the District classification category determined using the reading VAM scores and their standard errors as described previously.
If any of the points assigned to teachers in groups CORE or NON-CORE are based on fewer than 10 students, compare that number of points with the number assigned to the school-wide group, and assign the higher number.
