PRECISELY.
We afterschool language arts, and have from the beginning. Letting the school set the pace there has not been acceptable and this has been true even with a fabulous teacher that my DD has looped with since 8th grade.
The curriculum alone just isn't meaty enough for her to sink her teeth into. It's like she's starving for more, and school certainly isn't giving it to her. Even in terms of her writing, while she can meet demands, the real problem is that the demands stop short of what she actually needs to be learning.
