Developed collaboratively by leading classroom teachers and linguists of Korean, High Intermediate replaces Advanced Intermediate as the third-year textbook in the popular Korean language-learning series Integrated Korean. All volumes are developed according to performance-based methodology and principles: contextualization, learner-centeredness, use of authentic materials, function/task-orientedness, balance between skill-getting and skill-using, and integration of speaking, listening, reading, writing, and culture. Grammar points are systematically introduced with simple but adequate explanations and abundant examples and exercises.

Each situation/topic-based lesson consists of objectives, pre-lesson topics, and conversation reading, further reading, and culture sections. Conversation and reading sections contain comprehension questions, grammar and usage, activities, and English translations. Vocabulary for each lesson appears conveniently at the bottom of the page.

Integrated Korean is a project of the Korean Language Education and Research Center (KLEAR) with the support of the Korea Foundation. In addition to the five-level Integrated Korean textbooks and workbooks, volumes include Korean Reader for Chinese Characters, Korean Composition, Selected Readings in Korean, Readings in Modern Korean Literature, Korean Language in Culture and Society, and A Resource for Korean Grammar Instruction. A dictionary of Korean grammar and usage is forthcoming.
