Global Scale of English (subtitulado en español)
The Global Scale of English is a numeric granular scale from 10 to 90 which measures English language proficiency and is comprised of the five communication skills of the CEFR: reading, listening, writing, spoken interaction and spoken production. It is the most academically robust and precise form of English language assessment to have ever been established and enhances the current common European Framework of Reference (CEFR) by showing the finer gradations. http://www.english.com/
