VIETNAMESE VIBES 1 ALIGNS WITH THE CEFR (COMMON EUROPEAN FRAMEWORK OF REFERENCE FOR LANGUAGES) COMPETENCE FRAMEWORK, ENSURING STANDARDIZED LANGUAGE PROFICIENCY ASSESSMENT. THE TEXTBOOKS ARE AVAILABLE IN THREE LANGUAGES: VIETNAMESE, ENGLISH, AND ITALIAN, MAKING THEM SUITABLE FOR A DIVERSE AUDIENCE. EACH OF THESE TEXTBOOKS COMPRISES 12 CONTENT LESSONS AND 2 REVISION LESSONS. THE REVISION LESSONS ARE SPECIFICALLY CUSTOMIZED TO ALIGN WITH THE PROFICIENCY TESTS CONDUCTED BY THE VIETNAM MINISTRY OF EDUCATION, WHICH ARE ALSO BASED ON THE CEFR FRAMEWORK. WITHIN EACH REVISION LESSON, THERE IS A COMPREHENSIVE FOCUS ON ALL FOUR ESSENTIAL LANGUAGE SKILLS: LISTENING, SPEAKING, READING, AND WRITING. FOR EACH SKILL, LEARNERS CAN ENGAGE IN TWO EXERCISES, OFFERING A WELL-ROUNDED APPROACH TO LANGUAGE ACQUISITION AND PREPARATION FOR PROFICIENCY ASSESSMENTS.
