Did you know that there is a price gap of over $500,000 between homes in the northern Altadena area and San Marino?

Even within the same Pasadena address, the preference for schools can vary significantly depending on which school district boundary you fall under. Pasadena is centered around the Pasadena Unified School District (PUSD), but nearby San Marino and Arcadia operate separate school districts, making it particularly important to understand the boundaries.

Schools that receive relatively good ratings within PUSD tend to be concentrated in the northwestern foothills. Eliot Arts Magnet Middle School has a GreatSchools rating of 8, and the Blair High School IB Program is known to be among the top performers in terms of academic achievement within PUSD. However, the overall average for PUSD is around 5 to 6, so it cannot be said that the entire district is consistently excellent.

This is why many families choose San Marino Unified or Arcadia Unified instead of a Pasadena address. San Marino Unified has an A+ rating according to Niche and an average GreatSchools score of 9 to 10, making it one of the top school districts in Southern California. San Marino High School is reported to have received a perfect score of 10 from GreatSchools. Arcadia Unified also has an A rating from Niche and an average GreatSchools score of 8 to 9, making it a long-time favorite among Korean families.

Looking at housing prices, the median value of single-family homes in San Marino is estimated to be around $2.5 million to $3.1 million as of 2025. Arcadia is more accessible, with a range of about $1.3 million to $1.8 million. The median value of homes in the general PUSD area of Pasadena is estimated to be around $1 million to $1.4 million. When translating the school district gap into housing prices, there is a difference of over $1 million between San Marino and PUSD.

The area most frequently chosen by Korean families in the Pasadena region is Arcadia. Arcadia has a high percentage of Korean residents (estimated at 15-20% of the total population), and community infrastructure such as Korean markets and Korean language schools is well established. While San Marino also has many Korean families, the entry prices are high, so if the budget allows, San Marino is often mentioned as an option, while Arcadia is a more realistic choice.

If you are considering options within the PUSD school district in downtown Pasadena, you might want to consider a strategy that includes applying to Magnet Schools. Some Magnet programs in PUSD can be applied to regardless of school district boundaries, and there are schools with high academic levels upon admission. However, since it is a lottery system and competitive, there are no guarantees. School registration usually takes place between February and April, so if you aim for admission in the fall semester, it is advisable to finalize your address before spring.

If you are choosing neighborhoods based on school districts in the Pasadena area, you can rank them as follows: San Marino (top-tier, high-priced) → Arcadia (upper-tier, mid-priced) → northwestern PUSD (middle-tier) → southeastern PUSD (lower-tier). The answer varies depending on where you balance your budget and school district level, but Arcadia seems to be the most popular choice in terms of value for money.
