The benefit of sending your child to IUSD is that, it's a school district with growing enrollment vs many older neighborhoods are now facing serious declines and school closures.
I graduated from ABC school district centered around Cerritos and its immediate areas bordering Lakewood, Artesia, and Hawaiian Gardens. For those who don't know where it is, it's near where 91 FWY meets 605 FWY.
For 2025 academic year, the district has 1400 graduating high school seniors vs 1000 elementary school intake. For the class of 2024, there was a decline of 356 students, and for class of 2025 it will be another 400.
The school district has 16% out of district transfer students. My daughter attends an elementary school in Cerritos with 4 kindergarten classes, 3 out of 4 are dual English/Mandarin immersion with many kids from outside district (including my daughter). But even with the added kids from other districts, the net gain is only +18 kids from last year.
The district is looking to close/merge schools to save money. Cerritos is an older neighborhood (compared to Irvine) with many empty nesters and old folks who will stay until they're carried off to the funeral home. There isn't much new construction and few young families moving in. Thus, the school district will face many challenges.
Nearby school districts like Downey also face the same challenges, with local births declining from 1800/year down to 1000/year over the past 2 decades. They have been able to maintain school enrollment through taking kids from nearby cities, but it has reached a limit where enrollment will decline.
Fewer kids means less money, and more school closures/mergers. For now this is an issue that IUSD does not have to deal with.
