If your DD is a chameleon, it might be best to help her establish that confidence in reading right now, rather than wait for school, when she's incentivized to hide her abilities in order to fit in. My chameleon DD started pretending she didn't know how to write a few weeks into K. Because she'd been feeling good about her reading before she showed up in K, she'd already shown off her reading skills to her teacher before she realized it was a problem for her awful, awful teacher.
My DD exhibited perfectionism that prevented her from reading aloud before she was 5. We'd seen her read some fairly advanced messages from signs, so we knew she could handle her basic readers, but she refused to perform. As her fifth birthday was approaching, I appealed to her competitiveness. I told her she was developing ahead of where I was in every way except one: I was reading books to my mom when I was four. Within the week, DD read to her mom, and within the month, her pre-K teacher had turned over story time to her.
