Why have this conversation early?
Most disagreements about feedback aren't really about the feedback — they're about unspoken assumptions on both sides. Agreeing expectations early gives you a shared reference point to return to when things get busy or tense.
Clarify your expectations as supervisor
Before the first draft arrives, decide what you're willing to commit to and what you expect from the PGR in return.
How many drafts of each chapter are you prepared to read?
How far ahead of a meeting should written material be submitted?
What form will your feedback take — margin comments, a summary letter, verbal, or a mix?
What length and standard of writing do you expect at this stage — exploratory 'thinking in print', or polished for a reader?
What will you do if a deadline is missed on either side?
Understand the PGR's expectations
Ask, don't assume. PGRs bring expectations shaped by prior study, discipline norms and cultural context. Some want detailed line edits; others want big-picture direction.
Agree in writing when, realistically, feedback will be returned.
Ask what specific aspects they want feedback on for each submission.
Check what kind of feedback has worked (and not worked) for them before.
Agree how you'll flag when a piece needs a substantive rewrite rather than tweaks.
