Where can I find a list of the ranges of the different instruments?

I have been able to find many places that will give me a maximum range for each instrument, but I am looking for a source that gives the range that perhaps you can expect that, say, some high-school student might know if they have been learning the instrument in school for 4–5 years. I guess the main point I am try to get across is “where can I find the range of the different instruments that I can actually expect people to be able to play?” By “instrument”, I mean flutes, oboes, saxophones, french horns, tubas, bassoons, things of that nature.
