Confusion that a school sans signboard caused

The other day I was accompanying a candidate for an examination under Non-Government Teachers' Registration & Certification Authority (NTRCA). The examination centre was a boys' school in the New Market area. Outside the examination centre confused candidates were asking if it was the right venue, as the school had no signboard with its name on it. However, the school authorities were kind enough to paste two copies of seat arrangement lists.
About five minutes before the examination started, a candidate was feverishly searching for his roll number in the seat arrangement list only to find out that he had come to the wrong venue.
To help the examinees find the venue of the examination on time, the NTRCA authorities could have mentioned the name and full address of the institution in the admit cards. And why on earth doesn't a school have a signboard with its name inscribed on it? Would the authorities look into the matter?
