The number of city students who declined to take the state tests reached an all-time high this year, officials said Wednesday, and new data from the city offers the most in-depth look yet into the small but growing movement.

In just two years, its numbers have jumped from just over 350 students to more than 7,900, with a presence in most parts of the city. That amounted to 1.8 percent of city students opting out of the math tests and 1.4 percent in reading — far smaller than the 20 percent of students who opted out statewide.

Here’s a more detailed breakdown of exactly where students opted out:
