Global consultancy McKinsey and Co has said that the majority of schools in the UAE could only be rated poor to fair, Gulf News has reported. Only a few schools in the country can be considered fair to good, and even fewer good to great, according to McKinsey's Dr Mona Mourshed. "School systems need to change their structure by establishing new institutions or school types, alter school years and levels, or decentralise system responsibilities," she said.
