Of course this is correct if one can already read. If you look at a former post of mine, my juniors and seniors mostly read at about a 5th grade level. That is the level at which they stopped formal reading class. From 6th grade on they have Language Arts where they learn only 10 vocab words/week. Up to 5th grade they learn whole word memorization. It is no coincidence that they are still stuck at an elementary reading level.
