Follow the Evidence — Change the System

Services are tailored to the needs of your jurisdiction or agency

We work to build your capacity to identify and address current and future policy and practice needs

We offer only services that we truly believe are needed and are a wise use of public dollars


JSP team members are consultants and public sector managers and leaders.

We bring a balanced perspective from across the criminal and juvenile justice systems. Our experience gives us credibility with local stakeholders, the creativity to troubleshoot and solve problems in a practical way, and the ability to view agencies in the context of systemic policy and practice. We know what it takes to make reform efforts successful.

JSP builds capacity.

In all our consulting engagements, we consider people's readiness to change, and we partner with local leadership to enhance their ability to sustain reform over the long term. Our work includes helping organizations instill a commitment to gather the necessary facts to make more informed, data-driven decisions. To encourage local ownership of the change process, we coach executives and—together with local representatives—co-facilitate planning and implementation, working behind the scenes to ensure success.

JSP brings practical strategies and solutions.

We emphasize objective, data-driven decision making throughout system reform. Over the past two decades we have authored or co-authored tools for system assessment, decision point mapping, policy modeling, data dashboards, risk assessment, population projections, and cost-benefit analyses. We bring the creativity, experience, and project management skills to apply these tools for a variety of initiatives. Ensuring the best fit for a jurisdiction—whether with a strategy, tool, or facilitator—is important to us. Our focus is on matching our services to what is in your best interest. We combine the knowledge of how to apply current methods with the ability to develop new solutions if existing resources do not meet your needs.

JSP Innovates.

One our innovative partnerships is with Michael Wilson Consulting, Inc. Together we offer jail population projection models and cost/benefit analyses to help county policy makers manage their correctional populations most efficiently. We work with local analysts to collect and analyze information from stakeholders and at system decision points (e.g., law enforcement, courts, jails, and probation) to create a profile of the current jail population, project future growth, and model the impact of potential policy changes. Although our analysts can project jail population trajectories given current jurisdictional policies, as well as model the impact of potential policy changes, this is only a snapshot at a point in time. JSP is uniquely positioned to offer groundbreaking, user-friendly models so that you can modify your projections on your own over time.
