CCSA Releases Academic Accountability Data including State and Similar Schools Ranks for Every School in California

November 1, 2016

Sacramento - The California Charter Schools Association released three new accountability tools that provide a variety of school level data for every traditional district school and charter public school across the state. CCSA is pleased to provide this school level data online in one location for families, teachers, charter school authorizers and school communities for critical decision-making purposes.

Accountability is a key ingredient in the success of California's charter schools. Charter schools have thrived, in part, because clear minimum academic performance standards have allowed high performing schools to flourish with autonomy and underperforming schools to close. In the current rapidly changing state and federal accountability landscape where the criteria assessing school performance is in transition, we know student learning remains the most important factor during charter renewal, and for parents and families deciding on the school that best meets the needs of their child.

"California's charter sector embraces high expectations of accountability, and we believe in sharing proactively academic results as part of our commitment to being accountable to the public and parents," said Jed Wallace, president and CEO, CCSA. "Parents and decision-makers are owed the right to make informed judgements. That is why we developed an accountability framework based on multiple measures for all schools across the state with tools similar to those that parents and the public were once familiar with and used to understand how schools are performing."

State Ranks and Similar Schools Ranks

To help schools and the public contextualize their performance, we have translated data from academic accountability reports into "state ranks" and "similar schools ranks." This is a sortable spreadsheet of all schools in the state. (See Background section for more information including how ranks were calculated.)

2016-17 Statewide School Accountability Spreadsheet

This comprehensive spreadsheet shows the results of every school based on CCSA's accountability framework that sets minimum academic accountability criteria to measure academic performance of charter schools. This tool contains a variety of comparable measures of student outcomes including state ranks, similar schools ranks, A-G completion rates, Average Point Difference Measure (APD) and Similar Students Measure (SSM). (See Background section for more information.)

School Academic Accountability Reports

Annually, CCSA publishes individual school Academic Accountability Reports that show the results of every charter and traditional school based on CCSA's accountability framework. CCSA's minimum academic accountability criteria do not apply if a school is: Alternative Schools Accountability Model (ASAM), Alternative, less than four years old, or has less than 30 valid test takers.

CCSA's straightforward and transparent accountability framework provides all charter schools with tools to examine their individual performance, as well as to provide vitally important points of comparison to help a school contextualize its performance for its authorizer, families, and entire school community. This framework sets minimum academic accountability criteria that guide CCSA's advocacy for renewing and replicating charter schools. CCSA uses these metrics as "initial filters" in its accountability framework. For renewing or replicating charter schools below all filters, CCSA engages in a deeper multiple measure review.

The state and similar school ranks are based on the following measures to better contextualize school performance:

  • State ranks: CCSA has created a weighted average of proficiency, called the Average Point Difference (APD). This measure uses current year CAASPP (California Assessment of Student Performance and Progress) data and takes into account the performance of every tested student in the school, not just those that are over the "met standard" bar. It helps a school understand how far above or below proficiency its students are performing.
  • Similar schools ranks: Also based on the current year CAASPP data, this measure helps schools benchmark their performance in comparison to others serving similar demographics of students statewide. This Similar Students Measure helps contextualize a school's performance, while accounting for all significant subgroups served by the school.

CCSA created the Similar Students Measure (SSM), as a key component of our accountability framework. The Similar Students Measure (SSM) identifies schools that over- and under-perform compared to schools serving similar students statewide. It functions as a "proxy value-add" measure by comparing each school's performance to a prediction based on how schools with similar demographic characteristics perform.

CCSA has created the Average Point Difference (APD) to help schools and parents better understand SBAC scale scores and interpret growth. APD is a measure that compares a school's SBAC scale scores by grade to the state standard for "met". The APD means that the average student in the school scored that many scale score points above or below the met standard. We believe that rather than using a percent met or exceeded measure that incentivizes schools to only focus on "bubble students", the APD instead encourages schools to help each student raise his or her score as high as possible each year.

CCSA believes that a small number of chronically underperforming charter schools threatens the overall success of the broader charter school movement. That is why annually, CCSA publicly calls for the nonrenewal of charter schools that are not meeting our minimum criteria for renewal.

All data is based on the data file released by the California Department of Education (CDE) on October 18, 2016.
