A government adviser says agencies should make sure people they recruit as carers can speak English before placing them in vulnerable people's homes.
Dr Shereen Hussein, scientific adviser to the Department of Health, told the BBC that poor language skills could lead to bad care and abuse.
Trying to teach carers English could cause tension or problems which "may result in mistreatment or abusive behaviour to either the care worker or the service user".
