SGP is a measure of how much a student improves his or her state test performance from one year to the next compared to students across the state with a similar score history.
mSGP Release Process
As a central tenet of AchieveNJ, educators are never evaluated on a single factor or test score alone, but on multiple measures of both effective practice and student learning. As part of this system, the state has committed to developing measures of student growth as required under the TEACHNJ Act signed into law in August 2012. By using a growth methodology to calculate student outcomes, the Department recognizes that students enter each grade level at varying starting points and with unique challenges and that we should focus on student improvement, rather than simply how many students attain proficiency.
New Jersey measures growth for an individual student by comparing the change in his or her achievement on the state standardized assessment from one year to the student's "academic peers" (all other students in the state who had similar historical test results). This comparative change in achievement is reported on a 1 to 99 scale.For a timeline showing the development of SGP and mSGP Data in NJ, click here.
Qualifying educators (of 4th-8th grade Language Arts and 4th-7th grade Math assessed by the state test) are assigned the median SGP (mSGP) score of all of qualifying students based on information submitted by the district (see this Course Roster Verification and Submission guidance for more information). Starting with 2014-15, educators who qualify to receive the mSGP score as one element of their evaluation will earn that score based on a) the most recent year or, b) the median of the previous two years combined – whichever is most advantageous to the educator. For more information, please see this Guidance on Multiple Years of Data to Calculate mSGP.
For mSGP to be part of a teacher's evaluation, the teacher must be:
For mSGP to be part of a principal/AP/VP's evaluation, that educator must be:
mSGP data are available only for those who teach Language Arts or Mathematics in grades 4-7/8 because their students typically have baseline and end-of-year test scores. Given that third grade is the first testing year, there is no baseline data to create an SGP for that grade.
The list of specific courses that a teacher may teach and receive an mSGP rating can be found here Contained in this list, however, are all pre-secondary education Language Arts and Math courses, for example, Language Arts (Grade 1). Normally, first grade teachers would not receive an SGP because their students are not taking the state tests. However, in a situation where a school is offering 4th grade students a first grade language arts course, teachers of this course would receive an SGP according to the three factors stated above. The full list of codes for all courses can be found here.
mSGPs are one of several measures used to examine the work of educators under AchieveNJ. In 2014-15, the mSGP counts for 10% of all qualifying educators' evaluations. To calculate a final evaluation score, mSGPs are converted to a 1.0 - 4.0 score according to the Median Student Growth Percentile Conversion Chart, then weighted and included along with the other components of evaluation. See the Evaluation Scoring Web Page for more information.
Yes. Evaluation data of a particular employee shall be confidential in accordance with the TEACHNJ Act and N.J.S.A. 18A:6-120.d and 121.e. Educator mSGP data should be handled in the secure manner one would treat, handle, and store any part of a confidential personnel record and should not be released to the public. The Department strongly recommends that districts store mSGP data in each educator's personnel file or in another secure manner that is easily accessible to the educator (either electronically or on paper).
