How many credits do you need be to considered a high school senior in Texas?

                        I'm considered a junior at the moment with 12.5 credits, and then I have 7 classes, which will give me 19.5 credits at the end of the year.  I've heard that it's 20, but that makes no sense to me, because then that would make it impossible for some juniors to move up even though they passed all their classes.  You need 26 credits to graduate, and I would have .5 more than I needed to by the end of next year.  Is it really 20 credits?  Or will I be considered a senior?
