The document outlines a 16-level assessment for English language learners. Each level focuses on specific language functions and grammar points. Students must demonstrate proficiency in areas like introductions, daily routines, past experiences, and hypothetical situations. They must also show accurate use of verb tenses, pronouns, prepositions, and other grammar structures. To pass each level, students must cover a percentage of points, speak in complete sentences, and have good comprehension. The goal is for students to develop fluency and the ability to communicate ideas and discuss topics across different tenses.
