Seconding MON's recommendation that you not tell her it'll be better next year, because if it's still not good enough, your DD is going to blame you, and things will be even worse at home than before.
Also, it's only January, and next year is a lifetime for a 7yo. If there's anything at all you could be doing now to advocate for your DD, I'd start doing it... and make sure she knows you're doing it. Just knowing that her mom is getting involved and taking her concerns seriously can be a big comfort to her.
