We used 6 at my most recent school: colours of the rainbow (minus indigo as it was too similar) with very clear descriptors of what that meant - in line with top 1% of the country, in line with top 10% of country etc, which we chose carefully using knowledge of our own cohort and how many were likely to hit those groups.

Another gem. Thank you.
I agree five is optimal.
