Will local schools be dealing with waves of immigrants?

Obama's Health and Human Services department reportedly says 96 percent of the unaccompanied alien children who recently entered the U.S. have already been placed with their. sponsors.

According to CNS News:

Kenneth Wolfe, deputy director for the Office of Public Affairs at ACF, told CNSNews.com on Friday that in 2014 (through the month of June),  96 percent of the 45,157 children -- or 43,341 of them -- who were transferred from the custody of Customs and Border Protection (CBP) to the ORR have been placed with sponsors inside the United States, including with family members.

That's a lot of children, most of whom will presumably be enrolling in U.S. public schools for the first time in the coming weeks.

Has HHS given local school systems any estimates how many of these new faces will be showing in their classrooms in August or September? Or are school systems on their own to adapt if waves non-English speaking students show up at the last minute? This has potential to become a critical issue in areas with large Central American immigrant populations.
