The worst classroom I ever set foot in was the ESL class full of Hispanic girls. Talk about attitude and mouth. Zero respect for anyone. Why they were in ESL was anyone’s guess because they spoke perfect English but the school gets $$$$ for ELS so why not. And it gets them out of another teacher’s hair for an hour.
They get placed in the ESL class simply because of a Spanish surname. I worked with one person at one engineering company, last name Rodriguez, who spoke perfect English but did not understand Spanish. She described how she was placed in an ESL class simply because of her last name.
