Where do we go from here? • Look at multiple forms of data • Common assessments • MCAS • Class work • Carefully crafted interventions • Interventions during school • Tutorial after school • Consistently use data to inform instruction
What is growth? MCAS shows how each student is achieving relative to state standards Is John proficient in 6th grade mathematics? Cannot compare John’s scaled scores from year to year Growth measures change in an individual student’s performance over time How much did John improve in mathematics from 5th grade to 6th grade? Did John improve more or less than his academic peers?
Student growth percentiles Each student’s rate of change is compared to other students with a similar test score history (“academic peers”) Growth is distinct from achievement A student can achieve at a low level but grow quickly, and vice versa The rate of change is expressed as a percentile. How much did John improve in mathematics from 5th grade to 6th grade, relative to his academic peers? If John improved more than 65 percent of his academic peers, then his student growth percentile would be 65.
Rules of thumb Typical student growth percentiles are between about 40 and 60 on most tests. Students or groups outside this range has higher or lower than typical growth. Differences of fewer than 10 SGP points are likely not educationally meaningful.
