The Invisible Line: Where is the Border?
In Ardmore, the school district boundary is primarily determined by the county line.
Lower Merion School District (LMSD): Located in Montgomery County. This covers the northern and eastern portions of Ardmore, including the historic downtown and Suburban Square.
School District of Haverford Township (SDHT): Located in Delaware County. This covers the southern and western portions of Ardmore (often referred to as the "Havertown side").
Pro Tip: Do not rely on a mailing address alone. Many homes with an "Ardmore, PA 19003" address are actually located in Haverford Township (Delco) rather than Lower Merion (Montco).

Lower Merion School District: The Gold Standard
LMSD is consistently ranked among the top three public school districts in Pennsylvania. It is known for its immense resources, diverse elective offerings, and the "choice zone," which allows some residents to choose between Lower Merion High (The Aces) and Harriton High (The Rams).
Academics: Offers a massive array of AP courses and the International Baccalaureate (IB) program at Harriton.
Real Estate Impact: Properties here often command a premium. However, Montgomery County property taxes are traditionally lower than Delaware County's on a percentage basis, though high property valuations can balance this out.
School District of Haverford Township: The Community Favorite
Haverford offers a "small-town" feel within a major suburb. While Lower Merion often grabs the national headlines, Haverford is a top-tier district that residents praise for its tight-knit community and excellent special education support.
Academics: Known for strong elementary programs and a high-performing high school that consistently sends students to elite universities.
Real Estate Impact: You can often get "more house for your buck" in the Haverford section of Ardmore compared to the Lower Merion side, though you should factor in Delaware County’s higher tax millage rates.
Key Considerations for Homebuyers
1. The Tax Equation
This is the biggest "gotcha" for newcomers. Lower Merion (Montgomery County) generally has a lower millage rate. Haverford (Delaware County) underwent a recent reassessment, and while the schools are excellent, the tax burden relative to home price is often higher than in neighboring Montco.
2. Walkability and Lifestyle
The Lower Merion side of Ardmore puts you closer to the Amtrak/SEPTA station and high-end shopping at Suburban Square. The Haverford side offers better access to local parks like Haverford Reserve and a more "neighborhood" feel with traditional brick twins and single-family homes.
3. High School Athletics and Arts
If your child is a budding athlete or musician, both districts are exceptional. Lower Merion is legendary for its basketball program (Kobe Bryant’s alma mater), while Haverford is renowned for its music department and deep-seated rivalry with Upper Darby.
