The overall number of suspensions in NYC public schools has decreased dramatically. The odds that an individual student will be suspended have fallen too. For example, Research Alliance analyses show that in the 2008-2009 school year, 7.6% of first-time 9th graders were suspended at least once. By the 2014-2015 school year, that rate had fallen to 5.6%—translating to more than 1,500 students not receiving a suspension during the 9th grade.
These numbers reflect a districtwide push to reduce the use of suspensions, in response to growing concern about suspensions’ negative effects and the fact that, in NYC and nationwide, students of color and those with disabilities are disproportionately removed from class. In recent years, the NYC Department of Education has revised the school discipline code, encouraging alternative approaches to discipline and restricting schools’ ability to suspend students for “defying authority.”
The emphasis on reducing suspensions has not been without criticism. Some NYC educators and parents have argued that the new policy is making it harder for teachers to effectively respond to students’ behavior issues. Questions have also been raised about the reliability of data on safety incidents in schools.
Understanding what happens when a school district actively works to reduce suspensions—and what practices enable schools to meet this goal while maintaining a safe environment—will require good, in-depth research. (In fact, the Research Alliance is currently developing just such a study.) But there is a basic question that we can answer more immediately: Do NYC students generally feel safer in schools that issue fewer suspensions?
To begin exploring this question, we calculated the suspension rate  for the 769 NYC middle and high schools during the 2014-2015 school year. We also divided the schools into three categories based on students’ average responses to safety-related questions on the NYC school survey (for the same school year). The figure below illustrates our findings.
This analysis raises many questions about the relationship between schools’ approaches to discipline and students’ sense of safety. For example:
- What are the characteristics of schools with high perceptions of safety and low suspension rates? How do factors like a school’s size, neighborhood, resources, staff training, etc., influence disciplinary practices and perceptions of safety?
- How varied are perceptions of safety within schools? Do students within the same school generally have similar perceptions of the environment, or do some students feel very safe and supported, while others do not?
- What school practices hold the most promise for reducing suspensions and simultaneously improving safety? Which practices are related to more equitable student discipline outcomes (i.e., fewer disparities among those who are suspended)?

This post was developed using data provided to the Research Alliance for New York City Schools by the NYC Department of Education. David Kang conducted the analyses.
The suspension rate is the number of suspensions administered by a school divided by the total number of students enrolled at that school.
 The analysis focuses on the 769 schools with any students in grades 6 through 12 in the 2014-2015 school year.
 The measure of "I feel safe at school" is constructed as each school’s mean student response to "I feel safe in hallways/public spaces," "I feel safe in my classes," and "I feel safe outside and around school" on the annual school survey. “Less safe,” “moderately safe,” and “more safe” represent the bottom, middle, and top thirds of the distribution, respectively. It is important to note that these categories are relative and do not indicate not an absolute level of safety. For instance, “less safe” does not necessarily mean “unsafe”—it just means that a school is perceived to be less safe than the average NYC school. Likewise, indicating that a school is “more safe” simply means that it is perceived as safer than the average NYC school.
