Take a break before proofreading
Read slowly and focus on one type of error at a time
Check spelling and typos
Check grammar and sentence structure
Check punctuation
Check capitalization
Check word choice and consistency
Verify names, dates, numbers, and facts
Read the text aloud
Use a ruler or finger to track each line
Proofread on a printed copy if possible
Review headings, formatting, and spacing
Search for repeated or missing words
Use spellcheck, but do not rely on it completely
Compare the final version with the original draft
Proofread more than once
Ask someone else to review it
