Inside Jersey, a magazine produced by the Star Ledger, used a "proprietary formula" to chart trends in student achievement over the past four years.
The magazine used data from the state's High School Proficiency Assessment (HSPA), SAT scores and other data in its calculations to dole out letter grades.
Lawrence High School earned a "B" grade for above average scores and above average growth. The composite SAT score for a Lawrence
student was 1530. The student achievement was calculated at 5.6 percent from 2008-12, the time period over which the study took place.
