The sgpdata package contains 4 examplar data sets for use with student growth percentile (SGP) analyses. Two of the data sets sgpData_LONG and sgptData_LONG specify data in the WIDE format that’s used by lower level SGP functions like studentGrowthPercentiles and studentGrowthProjections. The other two, sgpData_INSTRUCTOR_NUMBER and sgpData_student_categorizing_variables, contain the variables required by higher level SGP functions like abcSGP, prepareSGP, and analyzeSGP.
Each year the state publishes SGP data for students and schools, which allows educators to see how their students are performing relative to academic peers across the state. These SGPs are not based on the students’ performance in any one year, but rather on their cumulative performance over time.
SGPs are calculated using a statistical method called quantile regression, which describes the relationship between a students’ previous score and their current year’s score. This methodology is a powerful way of assessing student progress because it provides information about how well a student is learning in relation to their peers.
However, it is important to remember that SGPs are based on trends in the statewide performance data and may not be representative of individual student performance in any given year. SGPs will shift over time, but these shifts are usually not dramatic. During the Covid-19 pandemic, for example, a large portion of the student population in Massachusetts experienced less growth than usual, but this was not typical of most years.
A student’s SGP is a number between 1 and 99 that indicates how much the student grew relative to their academic peers. For instance, a student with an SGP of 85 means that the student scored about the same as or better than about 85 percent of their academic peers on this year’s MCAS test in that subject area.
The SGPs released this year are preliminary and not intended for high stakes teacher evaluations until 2018/19, when high school students will be included in the analysis. This will give the state three additional years to stabilize this new data source.
SGPs are based on academic peer groups from grades 8 and 10 in the same school/district as the student tested in the spring, as well as their academic peers who have grade 8 MCAS data from another school/district in the state. Thus, students transferring to a school/district in grade 10 will have their SGP calculated using the academic peer group that they had in grades 8 and 7 as of the October SIMS data collection.
