PennPraxis' program evaluation practice is informed by the multi-disciplinary experience base of the Weitzman School's faculty and staff. Bringing training from the fields of design, econometrics, community engagement, data analysis and policy - the breadth of experience and depth of perspective allows Praxis to engage with a range of interesting projects. A multi-pronged, community-engaged research approach is frequently a part of any Praxis evaluation project, utilizing a broad set of strategies that include: in-person survey research, observational mapping, passive sensor data, open data exploration, spatial analytics, and focus groups. Praxis also engages in support of econometric evaluation research, especially that which involves the built environment or public policy.
