Below are the Reading/English Language Arts CPIs by subgroup on the 2012 MCAS exam for the KIPP Lynn Charter School. CPIs are a measure of the extent to which students are progressing toward 100% proficiency in ELA or math; the goal is a CPI of 100 which is the equivalent of all students having achieved proficiency on the exam. More specifically, each student participating in the MCAS is given a score based on well they perform on the MCAS which is later averaged among the district, school or subgroup to determine the CPI. Possible scores are 0 (Warning/Failing - Low), 25 (Warning/Failing - High), 50 (Needs Improvement - Low), 75 (Needs Improvement - High), and 100 (Proficient or Advanced).
