For the first time since Mayor Bill de Blasio took office in 2014, the number of suspensions handed out to students increased last school year.

In total, students received 36,668 suspensions during the 2017-2018 school year, a 4 percent increase compared with the previous year, according to new data released Wednesday. That increase comes after suspensions had tumbled dramatically in recent years, and as the education department has implemented reforms designed to curb the use of punitive discipline measures.

Aggregate suspension numbers, however, tell only part of the story. Here, you can find suspension numbers for every city public school for the past two years.

The numbers combine superintendent suspensions, which are issued for serious offenses, as well as principal suspensions, which are issued for more minor ones.

For privacy reasons, the education department does not disclose data if a school issues a small number of suspensions. Any field marked “redacted” means a school had somewhere between two and 10 suspensions. If a number has an asterisk, that means part of the school’s data was redacted, and could be off by as many as five suspensions. The data also excludes charter schools.
