International Scale of River Difficulty
The International Scale of River Difficulty is a standardized rating system used worldwide to classify how challenging a river section is for rafting and kayaking. It runs from Class I (very easy) to Class VI (extremely dangerous). When reviewing resumes for river guide positions, this scale helps recruiters understand a candidate's experience level with different water conditions. It's similar to how ski slopes use green circles, blue squares, and black diamonds to show difficulty levels. You might see it mentioned as "Whitewater Classification," "River Class Rating," or simply "River Rating" in job applications.
