Here is a link to Westminster High School: http://www.adams50.org/westminsterhs/site/default.asp - you may also want to give them a call at 303-657-3980 to get a specific list of documentation you will need to enroll your student in this school. They can also discuss open enrollment (when you live outside of the county you wish to enroll your student at). It has been my experience that open enrollment is on a first come first serve basis and is done prior to the upcoming school year. I know for some school districts the open enrollment period has already passed for the 2011-2012 school year. Again, these are all things that you can discuss when you call the main office of Westminster High School.
FYI, Westminster High School is in the Adams County School District. Here is their website if you need it:
Also, most school districts will require you provide them a copy of your current lease (since you are renting). See the registration tab under Parent Information (http://www.adams50.org/194710225172828927/blank/browse.asp?a )
Please let me know if I can answer any further questions you have.
