What is the SPI?The School Performance Index (SPI) is a comprehensive method for comparing the success of all schools – public and public charter schools – on on a variety of key components. Imagine 2014 called on the district to develop a method of ranking schools to identify those in need of intervention and those that should be rewarded with more autonomy.
The SPI combines and weights the following into a single calculated score: •student proficiency•student growth•student attendance •survey data•college preparatory data (high schools only)

Why use an index?Evaluating schools’ performance requires examining many
outcomes of academic progress and achievement as well as parent and student satisfaction.
The School Performance Index creates a score that is a composite of key indicators showing how each school is performing:
1. Relative to the District (or charters) Overall
2. Relative to Similar District Schools
Public Comment Draft
Why not just use Adequate Yearly Progress (AYP) to measure school performance?
1. SPI is more comprehensive: it incorporates many more measures than AYP.
2. SPI is more balanced: Making AYP is disproportionately difficult for schools with more ethnic, linguistic, and special needs diversity, because of the way “subgroups” are handled.
3. SPI puts focus on student growth: AYP is much less influenced by individual student growth than the proposed SPI.

Components of the SPI
Individual Student Growth
– Accounts for the differences in school populations—not all students start in the same place
– Credits schools where students make gains, no matter where they started

Components of the SPI
PSSA Proficiency– Students performing at
Pennsylvania Standard
PSSA “Below Basic”– Credits schools for helping
students move out of the lowest level
Achievement Gap– Credits schools for reducing the
District’s ethnic achievement gap

Similar Schools Rank• Each School’s Similar Schools Rank is based on its SPI
relative to the schools it is most demographically similar to.
• Although an Overall Performance Level is useful for comparing schools district-wide, SDP schools face distinct challenges related to their diverse demographics.
• When evaluating school performance, it is often more useful to compare schools with similar student populations.
• Every school has its own unique cohort.
Public Comment Draft
Similar Schools RankDemographic Factors:
• % Poverty
• % African-American or Latino
• % Special Education
• % English Language Learners
• School Selectivity [HS Only]
• measured by average 8th grade PSSA

Although it is difficult to display visually, mathematically we can add as many demographic dimensions as necessary
Each factor of the demographic comparison is calculated as compared to the reference school. The yellow circle displays an example reference school. The blue circle displays an example similar school.

What is the SPI used for?• The SPI has been used to identify the district's highest and
lowest performing schools.
• Schools that received a score of SPI “1” were granted Vanguard status and invited to participate in the Weighted Student Funding pilot as well as other opportunities for more autonomy.
• Schools that received a score of SPI 10 were selected for intervention, including: • Non-Empowerment SPI 10 Schools became Empowerment
Schools • Empowerment SPI 10 Schools were selected to be part of
the Renaissance Schools initiative.
