InsideSchools aims to provide the most up-to-date information on New York City's public schools. We rely on official statistics and information from the New York City Department of Education (DOE), which monitors most public schools. While some data was provided by special request, most of it is available to the public through the links below.
General school information
We aim to give families basic school information in an accessible format.
Contact and location
The DOE's LCGMS database is updated continuously throughout the school year. We use it to keep the following information up to date:
• Grade range
• Principal name
• Parent coordinator name and email address
• Street address
• Telephone number
• Subway and bus routes
The 2017-18 zone maps for elementary, middle and high schools are pulled from NYC Open Data.
Directory details (for high schools only)
The data in this section comes directly from the 2018 High School Directory, including:
• Descriptions of each program
• Admissions methods
• Foreign language and Advanced Placement courses offered
• PSAL sports teams
You can also view any information from the High School Directory in a new online app by the DOE called the NYC School Finder.
About our school stats
One goal of InsideSchools is to help families review and compare school performance outcomes from several data sets in one easy place. We believe that such statistics are only relevant when they are shown in the context of the student populations they serve. This is why we begin by describing the student body of each school and show how each statistic compares to a citywide average.
We use color-coded apples to show how well a school is doing compared to other schools across the city with the same grade levels. Schools that are better than the citywide average on a given indicator get a green apple. Schools that are worse than the citywide average get a red apple. Those that are around the citywide average get a yellow apple.
We use a common statistical calculation called a standard deviation to determine whether a given school is below average, near the average, or better than average on each data point. It allows us to easily see if a number is near the citywide average or substantially better or worse than the citywide average.
We calculate the citywide average for each type of school separately, so elementary schools are not compared to schools with grades k-8, for example. In many cases, this results in a difference between our averages and the official citywide averages published by the DOE.
Data sources and links
Almost every statistic displayed in InsideStats comes from one of the following publicly available datasets. For those who wish to delve deeper into the numbers or compare multiple schools, we link to those citywide datasets below. You can also view the data for an individual school on the "Statistics and Budget" section of your school’s DOE website.
At a glance
The 2016-2017 Demographic Snapshot provided the information on:
• Percent of students in each race/ethnicity category
• Free or reduced price lunch (schools that participate in the universal free lunch program are marked as 100%)
• Students with disabilities
• English language learners
• Percent of male students
The number of pre-kindergarten seats available and additional eligiblity requirements came from the 2018 Pre-K Directory.
About the school
• To identify which schools share a building with other schools, we matched up addresses of each school in the LCGMS Database.
• Uniform requirements came from the 2018 Middle and High School Directories.
• Data on metal detectors was originally collected as a joint project with the New York Civil Liberties Union and was updated by WNYC.
• Our statistic on school crowding came from the School Construction Authority's 2015-16 Enrollment, Capacity and Utilization Report. This figure is calculated by dividing the number of students enrolled in that year by the number of students the school—not the building—is designed to hold.
Safety and vibe
The 2016-17 School Quality Guide, which is the more detailed version of the School Quality Snapshot, provided data on:
• Average daily attendance
• How many students are chronically absent
• Years of principal experience at the school
• How many teachers have three or more years of experience teaching
• Teacher attendance
The rest of the questions in this section came from the 2016-17 NYC School Survey (formerly the Learning Environment Survey).
The 2016-17 School Quality Guide provided:
• Test scores for the New York State Common Core exams in English language arts and math
• The percent of 8th-graders earning high school credit, which is the portion of 8th-graders who both took and passed a high school-level Regents exam
• Percent of graduates who passed all their 9th-grade classes
• The three high schools most 8th-grade graduates attend
The 2015-16 Arts in Schools Report provided information about arts offerings and was generously prepared by the nonprofit Center for Arts Education.
• This report counts the total spaces at a school that are solely dedicated to the arts, not used as dual-purpose areas. These include rooms for music, theater, dance and visual arts as well as film studios and auditoriums.
• It also counts licensed arts teachers in music, dance, theater and visual arts. Teachers who spend only part of their time teaching these disciplines are indicated as "part-time."
Student opinions about the curriculum came from the 2016-17 NYC School Survey.
The accelerated courses offered for high school credit at each middle school came from the 2018 Middle School Directory.
Graduation rates and college readiness statistics came from the 2016-17 School Quality Guide, including:
• How many students graduate in four years?
• How many enroll in CUNY without remedial help?
Details about diplomas earned comes from the state-reported 2017 Graduation Outcomes, specificially:
• How many earn Advanced Regents diplomas?
• How man students drop out?
Special education and English language learners
Performance statistics for students in special education came from the 2016-17 School Quality Guide, including:
• Special education services offered
• Graduation rates
• Average test score for each sub-group of special education students
Survey responses from parents of students with disabilities came from the 2016-17 NYC School Survey.
The DOE publishes lists of schools adding transitional bilingual education and dual language programs each year. The 2017-18 list can be found here.
For questions or data requests
If you have any questions about the numbers, datasets or our calculations, please email Nicole Mader at email@example.com. If you see errors or miscalculations in your school's numbers, let us know and we will correct any problems as soon as possible.
We are also happy to assist school leaders, researchers or policymakers who are interested in working with this data. A long-term goal as we continue to improve our site is to make all our data available for download or through an API. Until then, feel free to reach out with any requests or questions.
