When you asked this question the other day, I answered it. I can see that you're confused, but you're posting this in a forum where the agents who are answering don't know what listing you're speaking of...so, none of us can help you without the address.
The boundaries can be confusing. For example, you can be about a mile west of Naperville Central HS (D203) and be in a different school district (D204). Just because it's the closest school doesn't mean it's the school your child will attend. Trulia puts the "closest school" in it's listings, even if your child can't attend that school. It's helpful when there is a private school nearby, which would provide parents with a choice. But, where public school boundaries are concerned, there are no choices.
There are 5 high schools which serve Naperville, 3 in D204 and 2 in D203.
If you aren't sure of the information on a consumer website like Trulia, I would urge you to contact an agent. We don't bite. :) We get these questions every day. It will save you the time, not to mention the uncertainty. An MLS search will provide the most up-to-date information, which is particularly important in rentals...the good ones go very fast.
If you would like to work via email, my contact information is below...or, feel free to call me.

You can't search for properties based on proximity to the school, in Naperville there are 4 high schools that students can to. You will have to search based on the school boundaries to make sure that Naperville Central will be the school. You could contact me and I will be happy to assist you. Mikegoodwin@mdgrealtor.com
