I have been searching for succinct language for referring to how "advanced" a topic or skill might be. I've found things like Integrative Complexity and the Model of Hierarchical Complexity, which seems to describe a school of thought, but falls short of providing consistent language for comparing examples within that school of thought. By "advanced", I am intending to communicate a greater amount of pre-requisite knowledge and/or a higher degree of complexity.
I toyed around with some terminology such as "Depth of Knowledge Required" at first, but it seemed lacking to me for some reason.
Is there a published set of language one could refer to in order to describe the concept of how advanced/complex a particular topic or skill is?
An example application where this terminology would be helpful could be in determining what the appropriate course of action would be to introduce a concept/topic to another person. For clarification, how would I compare the following two examples:
Computational Genomics in general might require additional knowledge compared to biological taxonomy
Non-linear dynamics involves many more pre-requisites than does algebra.
It's not that either option can't be complex or involve high level work, but to engage with the topic for the first time one clearly would be more difficult to approach than the other.
