For those of you who are planning to buy a home in the portland area (or moving from out of state) I found some great school locator links.
For portland, the website below gives information on what school your child will attend when you enter a home address in the portland school district: http://www.pps.k12.or.us/departments/enrollment-transfer/6478.htm
For the Beaverton school district, they do not quite have a locator site like the portland school district, but instead a file that lists each street address. Users will have to manually search for the home address they are putting an offer on and cross-check that with the school their child would go to. Use this document for reference.
It is the same for Hillsboro school district, check out the following link. It has a map of the district with all the schools highlighted.
