What is an Academic Peer? The New Hampshire Growth Model measures student growth by taking account of where a student starts and uses NECAP results for all New Hampshire students in a given content area and grade to quantify each student’s annual progress. The resulting metric is called a student growth percentile. Similar to height and weight percentiles used to describe the relative height and weight of an infant as compared to other infants of the same sex and age, a student growth percentile describes the relative academic growth a student made compared to other students with the same achievement history—their academic peers. Academic peers are not an actual set of students but are constructed using all the state’s data. The following slides illustrate what an academic peer group is and the way that student assessment data is used to create a student growth percentile.

What is an Academic Peer?
The New Hampshire Growth Model measures student growth by takingaccount of where a student starts and uses NECAP results for all NewHampshire students in a given content area and grade to quantify eachstudent’s annual progress. The resulting metric is called a studentgrowth percentile. Similar to height and weight percentiles used to
describe the relative height and weight of an infant as compared to otherinfants of the same sex and age, a student growth percentile describes
the relative academic growth a student made compared to other studentswith the same achievement history—their academic peers. Academicpeers are not an actual set of students but are constructed using all thestate’s data. The following slides illustrate what an academic peer groupis and the way that student assessment data is used to create a student
growth percentile.
