Original Research by School Decision on Mcdaniel Delaplaine Sch
McDaniel Delaplaine Sch serves kindergarten through eighth grade and sits in Philadelphia's South Philadelphia neighborhood. The school has enrollment of about 230 students. Essentially all students qualify for free or reduced-price lunch. The student body is predominantly Black, with smaller populations of Hispanic, Asian, and multiracial students. Data on the share of students with disabilities or English learners was not available.
The most recent state testing data, from 2024-25, shows proficiency rates that are well below district and state expectations. In mathematics, the school's proficiency rate was in the low single digits. In English language arts, the rate was in the low double digits. These results reflect a serious gap in foundational reading and math skills among the school's students. A parent may want to speak directly with the school's leadership about what instruction and supports are in place to close this gap, whether students are receiving intervention outside regular classroom time, and what progress the school has seen year to year.
Science testing from 2022-23, the most recent available, showed higher proficiency, though still a minority of students tested met proficiency. Scale score data for that year was reported.
The school uses the Pennsylvania System of School Assessment for all tested subjects. State assessment data does not report a graduation rate, because the school serves only through eighth grade. Attendance, chronic absenteeism, and discipline data were not available. Information about special education services, English learner supports, staffing, or course offerings was not in the data provided.
In the housing market around the 19145 ZIP code, median home values are moderate for Philadelphia and have declined slightly year over year. Rent is also moderate for the city. Combined with the affordability measures in the economic data, the area is substantially more affordable than the state and national benchmarks.
The Philadelphia City School District, which operates this school, is in the midst of major structural change. The district adopted new standardized curricula in math and English language arts starting in 2023-24 and 2024-25 respectively, moving to Illustrative Mathematics for K-12 and to a "science of reading" approach for ELA. This means instruction in reading and math at McDaniel Delaplaine is now uniform with the rest of the district. Early results showed a one-point decline in reading scores after the first year of the new ELA curriculum, with two-thirds of students still not reading at grade level across the district. Separately, in April 2026 the Board of Education approved a major facilities and consolidation plan that closes schools, merges programs, and modernizes campuses over the next decade. This plan will reshape school catchments and buildings across Philadelphia beginning in 2026-27. A parent should confirm whether McDaniel Delaplaine is affected by those boundary or consolidation changes.
