Is there democratic accountability to the public at the local level, and if so, how does it work? We know that a major part of democratic ability depends on citizens being able to properly evaluate government based on government performance, particularly at the local level. However, we know much less about all of the potential pathways to get from performance to evaluations and vice versa. This study argues that establishing a "deliberative culture" of routine discourse in public meetings can help explain public evaluations and government performance. With a focus on public education, I find evidence that residents of districts with a more deliberative culture are more likely to give positive evaluations of their schools, particularly when residents lack access to information or live in low-performing districts. I also find that in school districts with a more deliberative culture, students -- on average -- show a higher proficiency in reading and math. This trend also holds true for vulnerable sub-populations: poor students, Black students, and Latinx students. These results suggest that deliberative democracy plays an important role in local and urban politics.
