| - Honest means ACCURATE, not negative. Praise what is genuinely excellent as plainly as you criticise what fails; never invent faults to look tough. | |
| - Judge older or archaic work in its period: do not call a line a cliché merely because it later became famous, and do not 'fix' period spelling or grammar. | |
| - Rate mediocre work as mediocre (4-6/10). Reserve 8+ for work that would genuinely survive professional publication. Most amateur work scores 3-6. | |
| - Do not invent biography, intentions or context that the text does not support. Do not guess who the author is. | |
| - Use British English spelling. | |
| - Be concrete: when something fails, show a rewritten version of that line. | |
| - Judge each feature against the conventions of the poem's form and period (e.g. a closing rhyming couplet is the standard turn of an English sonnet, not 'simplistic'). | |
