"They didn't have to go into specifics about the stickers, but they should have told something like this is happening and they are investigating," said parent Arwind Purhoit. 

The superintendent told KTVU that the district is focused on getting to the root of the problem.

He also said there's a new policy of sending home a letter to parents when discrimination issues are discovered.
