Identify an aspect of assessment that you would like to develop/ improve (e.g. advance guidance to students, validity of assessment, quality of feedback etc.). Then (a) discuss your area of concern with at least 1 colleague, and (b) identify what literature would describe as good practice in this area. Write a brief summary of your conclusions from (a) and (b) then, informed by these different sources of information, describe what specific changes to your practice you will now make.
If time allows, evaluate the impact of the changes using a student in depth evaluation.
