Is Columbine High School the only public high school in Littleton?

No, actually Columbine High School is in South Littleton, within a five mile radius you have Dakota Ridge High School, Chatfield Senior High, and Colubine High School

Columbine and the other Jefferson County schools aren't even technically in Littleton. They're a part of unincorporated Jefferson County. But they use a Littleton mailing address, and we call that whole part of town Littleton, so we tend to think of it all as being one really big suburb called Littleton!

No, Columbine High School is just one of the High Schools in Littleton. Columbine High School is part of Jefferson County Public Schools. If you live in Littleton and are in Jefferson County, you could be within the boundaries of either Dakota Ridge, Chatfield, or Columbine High Schools. If you are further east and reside within Arapahoe County, you are in the Littleton Public Schools District. The three high schools in Arapahoe County are Heritage, Littleton and Arapahoe High Schools.

No, there is also Littleton High School, Arapahoe High School, and Heritage HIgh School. They also have what's called Options High School which I believe is on South Acoma Street. This high school has smaller classes and is more for high-risk teens and pregnant teens. They focus on career counseling and getting the kids back on the right track.
