Purpose: This study examines differences in the mechanisms that charter schools and traditional public schools use to facilitate parental school involvement and the degree to which these differences account for the high levels of involvement among charter school parents. Data and Research Methods: We merge data from principals and teachers from the nationally representative Schools and Staffing Survey and National Teacher and Principal Survey with nonprofit tax data from the National Center for Charitable Statistics. We use ordinary least squares regression to explain how charter and traditional public schools involve parents in communal, public-good activities, and individualistic, private-good activities within schools. Findings: Charters are less likely than traditional public schools to use bureaucratic structures, like parent–teacher organizations, and more likely to use nontraditional and less bureaucratic structures, like parent workshops and compacts. The use of such structures mediates a portion of the charter advantage; however, they only partially explain the association between being a charter and parent involvement. Additionally, we find some of the outreach structures that are most common in charter schools, including compacts, are also more strongly associated with parent involvement in charter schools than in traditional public schools. Implications: While charters have more public-good and private-good parent involvement than traditional public schools, our results suggest that the uncritical adoption of outreach strategies from one sector to another is unlikely to result in equal gains in parental involvement.

目的：本研究探讨了特许学校和传统公立学校用于促进家长学校参与的机制的差异，以及这些差异在多大程度上说明了特许学校父母之间的高度参与。数据和研究方法：我们将全国代表性的学校和人员调查以及国家教师和校长调查的校长和教师数据与国家慈善统计中心的非营利性税收数据合并。我们使用普通最小二乘回归法来解释特许学校和传统公立学校如何让家长参与学校内的公共，公共物品活动以及个人主义，私人物品活动。发现：与传统的公立学校相比，宪章更不可能使用官僚结构，例如家长教师组织，而更有可能使用非传统的，不那么官僚的结构，例如家长讲习班和契约。这种结构的使用介导了部分租船优势。然而，他们仅部分解释了章程与父母参与之间的联系。此外，我们发现，在特许学校中，包括契约在内，最常见的外展结构与家长在特许学校中的参与比与传统公立学校之间的联系也更紧密。含义： 尽管宪章比传统的公立学校拥有更多的公共和私人利益的家长参与，但我们的结果表明，不加批判地从一个部门到另一个部门采用外展策略不太可能导致父母参与的平等收益。
