According to The Common European Framework of Reference for Languages (CEFR), advanced English users can understand a wide range of more difficult, longer texts and recognize implicit meanings.    Advanced English speakers can also:   Express themselves fluently and spontaneously without searching for words. Write clear, well-structured and detailed texts on complex subjects. Understand long and complex texts, including abstract, poetic and literary texts. Participate actively and spontaneously in conversations using idiomatic speech. Easily understand English speech spoken at a native pace in a variety of accents. Watch and understand native movies and TV without subtitles.
