About Our Data

How we evaluate schools

Our school reviews are based on both quantitative and qualitative information. For each school, we analyze the schools stats we publish from the Department of Education, listed in more detail below. We also read through the school's most recent Quality Review (formal evaluations by trained educators) and Comprehensive Educational Plan (annual plans written by school staff).

As often as possible, we visit schools in person to write reviews. These visits usually take 3 to 6 hours to sit in on classes and interview the principal, teachers, and sometimes parents and students. We look for well-equipped classrooms, a high level of engagement among the students, lively class discussions, good examples of student work, imaginative lessons and a well-rounded curriculum that includes art, music, science and social studies. We ask and observe how teachers reach a range of pupils, how they handle discipline, and whether the school welcomes children and parents of all different backgrounds. Some of our staff have visited and reviewed hundreds of schools.

We list as Staff Picks schools that do well on all or almost all these measures. Staff picks for special education are schools with high academic standards (reflected by better-than-average test scores among children with disabilities), that treat all children kindly, and that serve a substantial number of special needs students.

We list as Noteworthy schools that do well on many but not all of the measures we take into account. These include new schools (which may not yet have a full complement of grades or a graduating class) and schools we have not visited recently. These lists are not exhaustive and we welcome additional suggestions.

School Stats

Teacher effectiveness data comes from section 1.2 of the school’s most recent Quality Review: “Develop teacher pedagogy from a coherent set of beliefs about how students learn best that is informed by the instructional shifts and Danielson Framework for Teaching, aligned to the curricula, engaging, engaging, and meets the needs of all learners so that all students produce meaningful work products.” We assign stars based on the school’s rating: underdeveloped = 1 star; developing = 2 stars; proficient = 3 stars; well-developed = 4 stars.

What is Pre-K like?
We assign stars based on the school's rating for Classroom Assessment Scoring System (CLASS) and Early Childhood Environmental Rating System (ECERS-R) (1 star = "inadequate or minimal, low-range", 2 stars = "developmentally appropriate, mid-range", or 3 stars = "strengths, high range")
• Instruction: Teachers ask kids to explain their reasoning when they solve problems.
• Activities: Children explore art, music, sand/water, dramatic play and more.
• Interaction: Teachers ask kids good questions and invite back-and-forth conversation.
• Language: Teachers talk and listen to kids in a supportive way.

About our apples

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 serving grades k-5 are not compared to schools with grades k-8 and stand-alone high schools serving grades 9-12 are not compared to schools with grades 6-12, for example. In many cases, this results in a difference between our averages and the official citywide averages published by the DOE.

For Questions or Data Requests

If you have any questions about the numbers, datasets or our calculations, please email Nicole Mader at [email protected]. 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.
