School Performance Measure
Updated March 2018The School Performance Measure (SPM) reflects City Schools’ values, including the cultivation of a nurturing learning environment for student growth. Collectively, a school’s teachers and school leadership play an instrumental role in affecting school climate, and the measure has served as a component of teacher and school leader evaluation systems since SY 2014-15.

SPM reflects a whole school’s year-long performance. Data are lagged, reflecting the previous school year, because data are not yet available for the current school year. As in previous years, SY 2017-18 SPM will include a score in learning environment for all schools. High schools receive additional indicators of college and career readiness. In SY 2017-18, no schools receive achievement or student growth data as a result of the transition to PARCC.
SY 2017-18 SPM Indicators
Norming: Schools are scored relative to one another
Beginning in SY 2014-15, schools were scored relative to all other schools in their grade band for SPM. As a response to stakeholder feedback requesting consideration of school context in SPM scoring, beginning in SY 2016-17, each school has been scored relative to its four nearest neighbor schools. "Nearest neighbors" does not mean that the schools are georgraphically close to one another. Rather, these are the specific schools within each school’s grade band (E, EM, M, MH, H) who serve the most similar students in terms of:
- Percentage of students with economic disadvantage*
- Percentage of students with disabilities
- Percentage of English learners
Focus group feedback included confirmation that these three characteristics impact instruction and school supports.
In addition, selective high schools constitute their own grade band for school comparisons, so that selective high schools are only normed with other selective high schools, and non-selective high schools are only normed with non-selective high schools.
* As a proxy for economic disadvantage, City Schools uses the proportion of students receiving direct services, including Temporary Assistance for Needy Families (TANF) and the Supplemental Nutrition Assistance program (SNAP), as well as homeless students, students in foster care, students eligible for Medicaid, and students scoring at beginner or low-intermediate English language proficiency levels.
Once each school's nearest neighbors are identified, each indicator is percent rank scored within each school's nearest neighbor group in increments of 20 to 100. We know that our schools are all pushing for the success and progress of each student. In order to reflect schools that maintain a high level of performance as well as schools that are demonstrating accelerated growth for their students, some indicators have both absolute and change scores.
Schools receive only the higher score, absolutely or change, in SPM. This also means that multiple schools who are nearest neighbors may receive the same percent rank score on the same indicator. Schools can tie to receive the same score, each school's nearest neighbors can be different, and some schools receive the absolute score while others receive the change score.
Note that nearest neighbor groups may change slightly due to missing data.
Lagged Data: Based on your school assignment
As noted above, data for SPM is lagged by one year. To ensure that SPM scores in an educator's evaluation are reflective of the school community they served, teachers and principals are given an SPM score based on where they were assigned in the previous school year. This means that their SY 2017-18 SPM score is based on where they worked in SY 2016-17. If they were assigned to multiple schools or if they changed schools during the year, teachers and principals receive a prorated score that incorporates data from the schools to which they were assigned.
Teachers and principals new to City Schools in the 2017-18 school year, those on leave for 2016-17, and those in district office or alternative schools or programs for 2016-17, will not have SPM as an evaluation component. As a result, the other components of the effectiveness evaluation are reweighted.
Review your SPM school-level report
In response to educator feedback, this year will be the first year that both teachers and school leaders are able to access the school-level SPM report that is included in their effectiveness evaluation via Employee Self-Service. These SPM reports align with the SPM score that will be included in their evaluation. As a reminder, this is based on where the teacher or principal worked in the previous school year.
School leaders will continue to have access to their school's current SPM report via Principals Dashboard. Teachers who switched school assignments this school year and are interested in reviewing the school's SPM results - even though its score will not be calculated in their evaluation - should contact their school leader.
At a glance
- The school performance measure will account for 15% of the overall 2017-18 Teacher Effectiveness Evaluation
- The measure is based on data from the 2016-17 school year
- All teachers at the same school in the 2016-17 school year will receive the same score
- Teachers who served more than one school in 2016-17 will receive a prorated score
- Teachers who are missing SPM will have other components of the evaluation reweighted
