Growth depends on genetics (some turtles grow faster than others), diet (what and how much the turtle is fed) and habitat (including how warm the environment is).
Captive RES, partly because some keepers tend to overfeed them, seem to generally reach around 4 inches (sometimes more) in the first year. Bigger is not necessarily better, though. Slow, steady growth is preferable, and a shell length of around 3 - 3.5 inches is better.
Some say that an inch of growth a year is pretty much the guide, but to me it can be more variable than that. The fastest growth takes place in the first 3 years and subsequently slows down.
