The SARA model is a four-step problem-solving framework used in policing: Scanning, Analysis, Response, and Assessment. Rather than reacting to individual 911 calls, it pushes police departments to identify recurring problems, understand their root causes, design targeted solutions, and then measure whether those solutions actually worked. It’s the backbone of what’s known as problem-oriented policing, and a review of the ten most rigorous studies on SARA-based strategies between 1993 and 2006 found they achieved statistically significant reductions in crime and disorder compared to traditional policing approaches.
How the Four Stages Work Together
Each letter in SARA represents a distinct phase, and they’re meant to be followed in order. The model is cyclical: if the final assessment reveals the problem hasn’t improved, the process loops back to an earlier stage. Here’s what happens at each step.
Scanning
Scanning is about identifying and defining the problem. Instead of treating every incident as isolated, officers and analysts look for patterns: a cluster of car break-ins in the same parking garage, repeated domestic violence calls at a specific address, or a spike in robberies along a particular bus route. The goal is to move beyond symptoms to spot a recurring issue that deserves focused attention. During this phase, departments pull together initial data from crime reports, calls for service, community complaints, and officer observations to confirm the problem is real and significant enough to warrant deeper investigation.
Analysis
This is the stage most traditional policing skips, and it’s arguably the most important. Analysis digs into why the problem keeps happening. A key tool here is the problem analysis triangle (sometimes called the crime triangle), which is built on a simple idea: crime occurs when three elements converge in the same place and time. There must be a motivated offender, a suitable target, and the absence of someone or something capable of preventing the crime. If any one of those three elements is missing, the crime typically doesn’t happen.
So during analysis, officers and analysts ask specific questions. Who are the offenders and what motivates them? Who or what are the targets, and what makes them vulnerable? What about the location or time of day allows the offender and target to come together without anyone intervening? Departments use both quantitative data (crime maps, statistics, call logs) and qualitative research (interviews with victims, offenders, and community members) to build a complete picture. The point is to find the weakest link in the triangle, because that’s where an intervention is most likely to succeed.
Response
With a clear understanding of the problem’s causes, the response phase involves designing and implementing a tailored intervention. This is where SARA most clearly breaks from traditional policing. The solution doesn’t have to be more patrols or more arrests. It might involve working with a property owner to improve lighting in a parking lot, partnering with social services to address homelessness near a transit station, or collaborating with schools and community organizations to redirect at-risk youth. The response is shaped entirely by what the analysis revealed, and it often involves agencies and stakeholders beyond just the police department.
Assessment
The final stage measures whether the response actually reduced or eliminated the problem. Did calls for service drop? Did crime incidents decrease at the target location? Did the community notice a change? Assessment can be as simple as comparing before-and-after crime statistics, or as rigorous as a formal evaluation with control groups. If the problem persists, the findings feed back into the scanning or analysis phase, and the cycle starts again with better information.
The SARA Model in Practice
Some of the strongest evidence for SARA comes from well-documented case studies in American cities. Boston’s Operation Ceasefire, launched in 1995, followed each SARA stage to tackle gang violence and youth homicide. An interagency working group identified the problem, researchers used both qualitative and quantitative methods to understand the dynamics of youth violence, and the team designed a focused intervention targeting gang activity and illegal gun possession. The result: a 63 percent reduction in the average number of youth homicide victims, along with significant decreases in gun assaults and calls for service across the city. A related study found a 24.3 percent drop in new handguns recovered from youth.
Boston also used the model in its Safe Street Teams initiative, which identified 13 violent crime hot spots using mapping technology. Over a 10-year observation period, areas where the SARA-based interventions were deployed saw a 17.3 percent reduction in total violent crime, a 19.2 percent drop in robberies, and a 15.4 percent decrease in aggravated assaults compared to areas without the program.
In Jersey City, New Jersey, a problem-oriented policing intervention in violent crime hot spots followed the SARA framework and produced significant reductions in disorder, calls for service, and criminal incidents at targeted locations versus control sites. Across multiple studies, the pattern holds: one review found that problem-oriented policing using the SARA method was associated with a 33 percent drop in street violence compared to traditional policing.
Why Analysis Is Often the Weak Link
The SARA model looks straightforward on paper, but the analysis stage is where many departments struggle. The National Institute of Justice has noted that current practice often falls short during this phase, with officers rushing from scanning directly to response without fully understanding the underlying causes. When that happens, departments end up applying generic solutions to specific problems, which undermines the entire approach. Truly effective analysis requires time, data access, and often collaboration with researchers or analysts, resources that many departments lack or don’t prioritize.
The problem analysis triangle, while useful, can also be difficult to apply in practice. Figuring out exactly what the “real” problem is, as the Center for Problem-Oriented Policing at Arizona State University acknowledges, is often the hardest part of the process. A spike in burglaries might seem straightforward, but the root cause could be anything from a new drug market driving theft to a change in work schedules that leaves homes empty at predictable times. Getting the analysis wrong means the response targets the wrong thing.
How SARA Differs From Traditional Policing
Traditional policing is largely reactive. Officers respond to calls, take reports, make arrests when possible, and move on to the next incident. The SARA model flips that approach by treating repeated incidents as symptoms of a deeper problem that can be solved, not just managed. It also broadens the definition of what counts as a police response. Instead of relying exclusively on enforcement, SARA encourages partnerships with city agencies, nonprofits, businesses, and community members to address the conditions that enable crime.
This matters because many recurring crime problems have environmental or social roots that arrests alone won’t fix. A convenience store that gets robbed repeatedly might need better lighting, a redesigned layout, or a change in cash-handling procedures more than it needs another patrol car driving past. The SARA model gives departments a structured way to arrive at that kind of insight and act on it.
