 challenges make it harder for students to be able to get all the staffing they need to fulfill those IEP goals. And even aides who need lesser qualifications, there's a shortage of them as well. And so a lot of students would really benefit from a one-on-one aide, for instance, or someone who can literally walk around the whole school day with them or help them in individual classes. And so when you don't have enough of those aides, then you have to make do and pair kids up more and not give quite as much as the one-on-one attention as they maybe deserve.
