To start with the numbers, the San Jose Unified School District has 46 schools with 25,409 students enrolled. In the past, when thinking of San Jose, the downtown school district would come to mind first, but now the Evergreen Elementary School District on the East Side and the Cupertino Union School District spanning the West Side are more frequently mentioned for their test scores. The Evergreen District received a Niche rating of A- and an 8 from GreatSchools, with 60% in math and 65% in reading meeting or exceeding state standards. The Cupertino Union School District has much higher scores, with 84% in math and 83% in reading meeting or exceeding standards; this district covers parts of San Jose westward, Cupertino, and Sunnyvale, adding another item to check. Even with the same San Jose address, the assigned school can vary significantly depending on which elementary district it falls under, so it's essential to first check the district boundaries, then the individual school ratings, and finally the recent test score trends. When moving to middle and high school levels, it's common for a separate unified school district to be in charge, so if you only check one elementary district, you might be surprised later when your assigned school changes.

The Korean population in Santa Clara County is 41,985, making up 2.2% of the county's total population of 1.9 million, which corresponds to the 99th percentile among counties nationwide and the 94th percentile within California. In the San Jose metro area alone, the Korean population was estimated at around 36,000 based on the American Community Survey from 2017 to 2019. There has been a trend of Korean families expanding their residences westward in San Jose and near Cupertino, as this area offers good access to Korean tutoring centers and churches, making it easier to establish a living infrastructure. However, this trend should be viewed as a reference for convenience rather than a separate indicator of school achievement.

Housing prices in San Jose remain high overall. Recent data shows the median price at $1,487,500, up 4.2% from the previous year, while Zillow's average home value is $1,462,209, which has increased by 0.7% over the past year. According to Redfin, the median price for the three months leading up to June was $1,500,000, which is a 0.76% decrease compared to the same period last year. Homes near high-achieving school districts tend to be more expensive than the San Jose average, so it's safer to look at recent price trends rather than hastily concluding that any district is guaranteed to rise. The unique employment trends in Silicon Valley's tech industry also reflect in the demand for listings, so examining local employment indicators can be helpful for decision-making.

To summarize the items to check, there are three main points. First, the assigned elementary and secondary school districts may differ by address. Second, due to the characteristics of Silicon Valley, the burden of housing prices relative to income is significant. Third, it's important to determine whether renting or buying fits your current budget. For families moving from out of state, it's also essential to consider that California's income tax rates and property tax structures differ from those of previous residences. For investors looking for rental income, areas near high-achieving school districts tend to have steady rental demand, but the high listing prices mean it's safer to approach yield calculations conservatively.

If you are a family just arriving from Korea and considering your first settlement, it's important to accept that it may be challenging to satisfy commuting distance, school districts, and Korean community infrastructure all at once. It's more efficient to set priorities and narrow down your search range.
