The most important (in my opinion) step in the formative assessment process is data USE. To be "formative assessment," either the teacher or the student has to USE assessment information to make a change (e.g. teachers using assessment data to make a teaching choice, students using feedback to revise their work, etc.)
Since USE is so important, I'd love to hear everyone's ideas for how you increase the chances that students USE the feedback teachers provide. Especially "reluctant" students: students who have already given up (there are lots of terms for thisL: fixed mindset, losing streaks, learned helplessness, low self-efficacy, etc.) When a student is convinced that they CAN'T learn, that trying won't help, how do you get them to try one more time, get feedback, and USE that feedback?
