Summary:

The 19018 zip code area is home to three elementary schools: Westbrook Park Elementary School, Primos Elementary School, and Aldan Elementary School. These schools serve students from kindergarten through 6th grade and are part of the Upper Darby School District and the William Penn School District.

Based on the data, Primos Elementary School appears to be the standout performer in the group, with the highest proficiency rates in math, English language arts, and science across all grade levels compared to the other two schools and the district/state averages. For example, in 2024-2025, Primos had 36.6% of students proficient or better in math, compared to 25.2% at Westbrook Park and 22.5% at Aldan. Primos also had the lowest student-teacher ratio at 11.6, compared to 13 at both Westbrook Park and Aldan.

However, all three schools in the 19018 zip code area have consistently ranked in the bottom half of Pennsylvania elementary schools based on the SchoolDigger statewide rankings, with Westbrook Park and Aldan being in the bottom 20% for the past three years. The data reveals significant performance gaps between the schools and the district/state averages, particularly in math and English language arts. This may be due to resource challenges, as all three schools have 100% of students receiving free or reduced-price lunch and relatively low spending per student compared to the state average.
