If you want a single number that captures what is happening to Anna, look at its school district. In the 2019-20 year, Anna ISD enrolled about 3,828 students. By May of 2025 that figure had climbed to roughly 6,148. That is on the order of a 60 percent jump in about five years — the kind of growth curve that forces a district to think less like a school system and more like a construction company that happens to teach children.
For families moving in, the practical questions are simple. How many campuses are there, how new are they, and is the district keeping up with the flood of rooftops going in on the edges of town. Here is the honest picture.
The district serves almost all of Anna — but not quite
Anna ISD covers nearly the whole city. There is a small sliver of Anna that falls into the neighboring Blue Ridge ISD, so if you are buying on the outer edge of town it is worth confirming which district your specific address belongs to before you assume anything. For anything past high school, Collin College is the local higher-education option that serves the area.
The district currently operates nine campuses: five elementary schools, two middle schools, one high school, and one alternative campus. What is striking is how young most of that lineup is.
The elementary schools, oldest to newest
Anna ISD runs five elementary campuses, and their opening dates read like a timeline of the town’s growth spurts:
- Joe K. Bryant Elementary opened in 2005, back when Anna was still a fraction of its current size.
- Sue E. Rattan Elementary followed in 2007.
- Judith L. Harlow Elementary opened a full decade later, in 2017, as the first wave of the current boom really took hold.
- Rosamond-Sherley Elementary opened in 2022, its name a nod to two families woven through Anna’s history.
- Lorenzo Dow Hendricks Elementary is the newest, having opened in 2025.
The clustering tells the story on its own. Two campuses in the mid-2000s, then a ten-year gap, then three new elementaries in under a decade. That is a district that spent years steady and then had to sprint.
Two middle schools, both brand-new
Anna’s middle-school picture changed sharply in 2023. That year the district opened two middle-school campuses at once: Slayter Creek Middle School — which was renamed from the former Anna Middle School — and the brand-new Clemons Creek Middle School. Going from a single middle school to two in one year is exactly the sort of move a district makes when its elementary campuses are about to push a much larger class up into sixth grade.
One high school, expanded twice
For now, all of Anna’s high-schoolers attend Anna High School. The current facility dates to 2011, and rather than build a second high school immediately, the district chose to expand the existing one — first in 2019 and again in 2022 — to absorb the growth. That is a common playbook: stretch the high school you have as far as it will reasonably go before committing to a second one.
Rounding out the nine campuses is the Anna Academic Achievement Center, the district’s alternative campus handling disciplinary placement and credit recovery.
The 2022 bond: what the district is racing to build
Here is the part that matters most if you are betting on Anna for the long haul. In November 2022, district voters approved a bond package aimed squarely at the growth problem. On paper, it funds a substantial slate of future construction: additional elementary campuses (numbered, in planning terms, as elementaries five through eight), two more middle schools (numbers three and four), and — notably — a second high school. It also funds a new administration building and service center, land acquisition for future sites, and further expansion at the existing Anna High School.
You do not commit to that many future campuses unless you expect the enrollment curve to keep climbing. The bond is essentially the district saying, in dollars, that the growth is not a blip.
What this means for a family choosing Anna
Two things are worth taking away.
First, most of the district’s buildings are new or nearly new. A family moving here is largely choosing between campuses opened in the last decade rather than aging facilities — a real advantage of arriving during a build-out phase.
Second, growth this fast comes with the usual growing pains. Attendance boundaries in a district adding campuses this quickly tend to get redrawn as new schools open, so the campus your address feeds into today is not guaranteed to be the one it feeds into in a few years. That is not a knock on Anna ISD — it is the mechanical reality of opening a new elementary school roughly every couple of years. The single best habit for a new Anna family is to confirm current attendance zones directly with the district each year rather than assuming they have held steady, because in a town growing like this one, they often have not.
