The High School of American Studies at Lehman College (also known as HSAS, or American Studies, but never Lehman, as there's another Lehman HS in the Bronx) already posted info about their fall tour:
It's on Thursday, 10/12 at 5:30pm.
Usually info for specialized open houses aren't available until the fall, so it's great to be able to get these on calendars early. Keep in mind, every specialized school hosts a fall open house. They're generally all scheduled in the 2 or so weeks before the SHSAT. They work to make sure none overlap, but other main round schools sometimes are happening at the same time.
