Are all bleep/beep tests done on a twenty metre distance?

I have been trying to improve my fitness the last month, Running every at a steady pace for 15mins I did the bleep test a few months ago in school and i got 10.1. I downloaded the bleep test last week and i cant get to the result i got in school! could the bleep test i downloaded be baced on a shorter distance than the one i did in school?
