That sounds like what NGA would call "applications", but with the formality of what we'd call "classical techniques" (our short forms). Seems like a similar approach, overall, except the organization by belt (NGA's doesn't have a similar clear cut delineation).
It might be worth adding that some associations choose to teach Hapkido by using forms just as TKD and others do. The Korean Hapkido Federation toyed with that idea back in the late mid-80s. My GM had us try some forms based on elbow strikes, and decided against their use. Ultimately the Federation scraped the idea.
