Charting Tips for CNAs
What to document, how to write it, and the habits that protect residents and your license.
By the CaregiverCert team · Updated October 24, 2026 · 5 min read
If it isn’t documented, it’s as if it didn’t happen. Your charting tells nurses how residents are doing, supports their care plans, and protects you. Federal rules require nursing home records to be complete, accurate, organized, and confidential (42 CFR 483.70(h)). Here is how to do your part well.
What CNAs usually document
What you chart depends on your facility’s system, but CNA documentation usually includes:
- Vital signs, height, and weight. Recording these is part of federal CNA training.
- Daily care: bathing, dressing, grooming, toileting, meals and fluids, repositioning, and walking.
- How much a resident ate, and intake and output when ordered by the facility.
- Changes you notice: skin changes, new pain, confusion, falls, refusals of care, or changes in mood or behavior.
Report first, then chart. Recognizing and reporting changes to the nurse is a core CNA skill. Tell the nurse right away about any change, then document it.
How to write good entries
- Chart what you saw and did, not guesses. Write “Resident ate 25% of lunch and said her stomach hurts,” not “Resident seems sick.”
- Be specific: amounts, times, and the resident’s own words in quotes.
- Chart at the time you give care, or as soon as possible. CMS expects services to be documented when they’re provided.
- Use only approved abbreviations from your facility.
- Be objective and respectful. The record should reflect what actually happened.
Never chart for someone else
Each staff member must have their own login, and electronic entries should not be changed after they’re recorded. Never chart care you didn’t give, never document under someone else’s login, and never share your password. Falsifying records can cost you your job and, in some states, your certification.
Fixing mistakes
Mistakes happen. Fix them the right way: a correction should show who made it and when, and the original entry shouldn’t be erased. On paper, that usually means a single line through the error with your initials, date, and the correct information. In an electronic record, use your facility’s correction or late-entry feature. Ask your nurse how your facility does it.
Protecting privacy
Residents’ health information is protected by HIPAA in any form: electronic, paper, or spoken. Share only what’s needed for care, don’t leave screens open where others can see them, and never post about residents on social media, even without names.
Frequently asked questions
What do CNAs chart?
Usually vital signs, daily care like bathing, meals, and toileting, how much residents eat and drink, and any changes they notice in a resident’s condition.
When should a CNA chart?
At the time care is given, or as soon as possible after. Don’t wait until the end of your shift.
How do I correct a charting mistake?
Follow your facility’s policy. Corrections should show who made them and when, without erasing the original entry.
Can I chart for a coworker?
No. Only document care you personally gave, under your own login.
