Given a choice, most of us will pick the powerful sports car over a sensible basic car to get from point A to B. Both vehicles can get us there, but the probability of an accident before
arriving at point B is greater in the sports car....
If the low end of the scale score band for Level 3 is say 100 scale score
points and student A scores 90 scale score
points on the Math SBA for their grade level, and student
B scores 110 scale score
points, and student C scores 115 scale score
points, the system subtracts each student scale score from 100
arriving at derived scores of -10, +10, and +15.
