One reason Rowland Heights has long been a popular choice for Korean families is its school districts.

Looking at the numbers, the difference in school ratings between the Rowland Unified School District (RUSD) and the adjacent Walnut Valley Unified School District (WVUSD) is typically 1 to 2 points higher on the GreatSchools scale, which directly correlates to home prices. The boundaries of the two districts intersect within Rowland Heights, making address verification crucial in this area.

According to data, the top schools in the Rowland Unified district include Nogales High School (GreatSchools rating of 7) and Killian Elementary (also around 7). The overall average for RUSD is between 6 and 7, which is considered upper-middle level within LA County. In contrast, the adjacent Walnut area's Walnut Valley Unified has an average of 8 to 9 on GreatSchools and an A rating from Niche, making it one of the top school districts in Southern California. Diamond Bar High School (part of WVUSD) is known as a prestigious school in the area with a GreatSchools rating of 9.

In terms of home prices, the median value of single-family homes within the WVUSD boundary in Rowland Heights is estimated to be around $1 million to $1.3 million as of 2025.

The RUSD boundary area is understood to be in the $800,000 to $1 million range. The overall median value in nearby Diamond Bar is about $1.1 million to $1.4 million, which is similar to or slightly higher than the Rowland Heights WVUSD area. The school district premium is reflected in home prices, ranging from $100,000 to $300,000.

Rowland Heights has a high percentage of Korean residents, with estimates suggesting that 15 to 20% of the total population is of Korean descent.

With a concentration of Korean markets (H Mart, Galleria Market), Korean restaurants, and Korean language schools, the living infrastructure for Korean families in this area is among the best in Southern California. For this reason, many families choose Rowland Heights even if the school district ratings are similar to or slightly lower than those in Diamond Bar or Walnut, due to the community infrastructure.

The northern and northeastern areas of Rowland Heights that fall within the WVUSD boundary (north of Colima Rd and parts east of Fullerton Rd) are known to be the most preferred areas in terms of school districts. In this area, there is a high likelihood of being assigned to Chaparral Elementary (GreatSchools rating of around 8) or Vejar Elementary. The most accurate way to confirm specific assigned schools is to enter the address on the official WVUSD website.

Compared to nearby cities, Rowland Heights maintains a unique position as a place that meets both school district and Korean community needs.

While purely in terms of school district quality, Diamond Bar and Irvine may lead, considering the Korean living infrastructure and the school district quality relative to prices, the Rowland Heights WVUSD area appears to be a very reasonable option. Diamond Bar also has a significant Korean population and consistently good WVUSD schools, but home prices tend to be 10 to 20% higher than in Rowland Heights.

If you are planning to move to this area, the first step is to determine which school district the property address falls under, whether RUSD or WVUSD. The boundary lines on maps are often divided along roads, so both sides of the same road may belong to different school districts. School registration deadlines are usually between February and April, and it is advisable to confirm your address six months before the start of the semester.
