What is shorthand for assessment?

There isn't one universally accepted shorthand for "assessment". However, depending on the context, you might use:

Formal:

* Assmt.

* Eval. (for evaluation, which is often used interchangeably with assessment)

Informal:

* Check-in (for a quick, informal assessment)

* Review (for a more comprehensive assessment)

Ultimately, the best shorthand depends on your audience and the specific context.
