# TODO: Include _assessment_sections test here?

[kallewesterling]

I think assessment should be auto-generated, based on lessons, perhaps with additional evaluative questions in the assessment.md file—or potentially inside the theory-to-practice.md file. (Self-)assessment should also include the "exit slip" questions, perhaps in its own section in the theory-to-practice.md, or in the assessment.md or its own .md file...

Either way, alpha-1 won't have assessment as a feature, so I'm adding it as a enhancement towards v1.0

Some of this was addressed in cff70dc. Renaming the issue accordingly.

Add new model with fields:

• title
• workshop
• question + answer (make similar to lesson.Question and [optional] lesson.Answer)
• date (needed as well)
• potential "code" or some other way to link these to specific occasions when workshops are taught?
