"I'd be very hesitant to accelerate a child without literacy skills at least a little beyond the destination grade. Writing skill weaknesses are one thing (that's pretty common), but reading skills can create global problems in grade 4 and up"

Is there any research/books/authors that provide estimates for the 'ideal' placement for an accelerated child within a class? I'm sure I've heard around the place that it would ideally an accelerated student should be in the top half of the class? Am I making this up?
