Summary

PS 270 Johann Dekalb is an elementary school located in Brooklyn, New York, serving grades PK-5 with 122 students. It is part of the New York City Geographic District #13, which is ranked 617 out of 874 districts in New York and has a 1-star rating from SchoolDigger.

PS 270 Johann Dekalb consistently ranks among the lowest-performing elementary schools in New York state, with rankings between 1,572 and 2,426 out of around 2,400 schools over the past 10 years. Its proficiency rates on state assessments are significantly lower than the district and state averages across all grade levels and subject areas. The school serves a high-needs student population, with 69-88% of students qualifying for free or reduced-price lunch over the past few years. Despite the high per-student spending (between $37,128 and $43,129) and a relatively low student-teacher ratio (9.5 to 10.1), PS 270 Johann Dekalb has not shown significant improvement in its academic performance over the past 10 years.

In comparison, the nearby schools such as PS 20 Clinton Hill, PS 3 Bedford Village, and PS 256 Benjamin Banneker generally outperform PS 270 Johann Dekalb on state assessments, with higher proficiency rates and better overall rankings. These schools serve student populations with lower percentages of free/reduced-price lunch recipients. The data suggests that PS 270 Johann Dekalb is facing significant challenges in effectively serving its high-needs student population and improving academic outcomes, despite the high spending and low student-teacher ratio.
