Last week, Sen. Elizabeth Warren released her education plan, where she proposed slashing federal funding for the expansion of public charter schools by ending the Charter School Program (CSP). Warren claims that the CSP is an “abject failure,” citing a report by an anti-charter organization that the federal government has wasted up to $1 billion on charter schools. (The report’s lack of substance and evidence has already been raised by others.)
I know Warren is wrong firsthand. As part of my work at Bellwether Education Partners, I serve as an external evaluator for three CSP grantees (as my colleague Cara mentioned yesterday). Our unbiased, rigorous, and data-driven evaluations indicate that when implemented well, high-quality charters use their CSP funds to improve their model and successfully serve more students. These charter schools are the reason their students experience gains in achievement beyond their traditional public school peers.
Let me step back. The CSP began in 1994 as an amendment to the federal Elementary and Secondary Education Act. It has three goals:
- To create promising new public charter schools,
- To replicate high-quality public charter schools, and
- To disseminate information about effective practices within charter schools.
In 25 years, CSP has awarded close to $4 billion to charters serving disproportionately more low-income and diverse students than traditional public schools. The average award is about $500K. In exchange for CSP replication funds, the schools expand to serve more students. CSP replication grantees are required to evaluate their progress, and it is strongly recommended that they use an external evaluator to do so. The evaluation must demonstrate that the grantee is doing what it said it would do and compare the achievement of its students to students attending nearby traditional public schools for evidence of impact. This is how the CSP holds grantees accountable.
My colleagues and I use advanced statistical modeling techniques to compare charter-attending students to similar students attending nearby traditional public schools on a 1:1 basis. In the model, when all things are considered, the difference in achievement found can be attributed to the school. In fact, an emerging trend in our current data analysis suggests that the longer a student attends a well-implemented, high-quality charter school, the larger the gains in achievement over their traditional public school student peer become.
