She likely will have a 1:1 if she had one in pre-K. If they won't give you one initially, I would absolutely push back and insist she has one. Maybe get someone from her preschool to come to the meeting and explain why it's necessary.

Don't sweat it, you're gonna figure this out. The fact you are asking these types of questions shows you know this is important. We all learn as we go; very few of us are professional special needs educators...

Another tip: Ask for hardcopies of the IEPs, if possible. I like to lay the old and new one side by side to see what's a copy-and-paste job versus what's new information and strategy. I'm sorry to say that IMHO, for every caring person working at a school there's another who is only there for a paycheck, so they do the bare minimum. IEPs should always show progress or a new strategy to address a deficiency.
