There are a lot of ways of assessing verbal proficiency in a language. Unsurprisingly, most of the research and teaching material are for language teachers and researchers.
However, I was wondering whether anyone knows of good scales or competencies that learners like to use to measure their own proficiency. To help them monitor their own progress.
edit: Good link to Flimsy's 2015 post. That was very helpful. I still think that a fluency scale that is understandable and intuitive for the learner and not dependent on external agencies such as ILR, ACTFL and CEFR is still helpful. Especially important for work and sensitive topics.
A proficiency scale that allows learners to figure out and map their competency would be ideal.
Edit: to change fluency to proficiency
