> According to one ranking, by EF Education First, an international language-training firm, China ranks 91st among 116 countries and regions in terms of English proficiency. Just four years ago it ranked 38th out of 100. Over that time its rating has slipped from “moderate” to “low” proficiency. Some in China question the accuracy of the EF index.<p>Yeah, people don't suddenly lose their English skills in the span of four years. Either EF changed their methodology or the ranking is so non-robust that it's essentially random.
