GothamSchools — daily independent reporting on NYC public schools

When test scores are released, individual schools often get lost in the big picture. To pull some out of the heap, I’ve created a way to look at each school’s results in a broad stroke: For every school in the city, I averaged the percentage of students who scored proficient across all the tested grade levels.

The following lists rank the highest- and lowest-scoring elementary schools in the city overall. It includes no charter schools and no screened schools. I did include schools with gifted and talented programs; they are denoted with a * next to their name.

Middle schools will come tomorrow. (And Kim Gittleson has done a similar analysis of charter schools; check it out.)

UPDATE: Three of these lists have been revised to add four schools missing from our lists due to an Excel error. The four added schools are:

• PS/IS 116 Wiliam C. Hughley, with 23.6% average proficiency on math, should have been on the math low-scoring list.
• P.S. 172 Beacon School of Excellence, with 99.6% average proficiency on math, should have been on the math high-scoring list.
• P.S. 172 Beacon School of Excellence, with 95.1% average proficiency on reading, should have been on that high-scoring list.
• P.S. 158 Bayard Taylor, with 90.5% average proficiency on reading, should have been on that high-scoring list.

Schools that would have been bumped off the lists because of these additions have been kept on.
