There is an existing discussion/request for a system to tag or otherwise indicate level of questions:
The idea is that people answering or searching could use this to filter questions. The indicator could for example be a tag, or else some other thing which is a required ingredient and would be selected from a pull-down list. Here is a possible set of choices for such a list:
- from zero to around early high school, including teaching of same
- advanced high school or university (undergraduate), including teaching of same
- graduate study to open research question
With this post I am re-asserting the existing request(s). It is true that the level of most questions becomes clear early on when reading the question, but a tag would help people wanting (3) to avoid looking at (1) altogether, and vice-versa. The choice of tag need not be checked by the system; if someone picked the wrong tag then they would simply reduce the chances of a response useful to them.
