What Is a CNA? Complete Career Overview

What Is a CNA? Complete Career Overview, Training Path, Pay and the Bridge to LPN and RN

A certified nursing assistant (CNA) is the bedside caregiver who keeps American healthcare running. CNAs handle the hands-on patient care that nurses delegate — bathing, feeding, transferring, toileting, vital signs, mobility, and the simple human dignity work that fills every shift in hospitals, skilled nursing facilities, assisted living, home health, and hospice.

In a 12-hour hospital shift a CNA might assist eight to fourteen patients. In a nursing home, the ratio runs ten to twenty residents on day shift and eighteen to twenty-five on nights. The role is physical, emotional, and the entry point most American nurses started from — roughly 40% of registered nurses began their careers as a CNA before bridging up.

The Bureau of Labor Statistics counts more than 1.4 million CNAs working in the United States. By 2032 that number must climb to 1.6 million to keep pace with the aging baby boomer population, and BLS projects 209,000 annual openings every year of this decade. Pay sits between $13 and $28 per hour depending on state, employer type, shift, and experience. Hospital systems anchor the top of the range, rural skilled nursing the bottom. Bilingual CNAs, those working specialty units, and travel CNAs earn $1 to $5 above base.

The credential is one of the fastest in healthcare. A 75 to 150 hour state-approved training program plus a single competency exam — written plus skills — gets a new CNA on the floor in 4 to 16 weeks. Tuition runs $300 to $1,500 at community colleges and many employers pay you to train if you commit to one year of employment.

The federal OBRA-87 minimum is 75 hours, but states layer their own requirements on top. California requires 160 hours. Maine requires 180. Alaska tops the list at 200. Most southern and midwestern states stay at the federal 75-hour floor.

This complete career overview walks through every part of the role — what a CNA legally can and cannot do, exactly how training works state by state, what the certification exam covers, what a normal shift looks like at 7 a.m. and at 3 a.m., realistic pay by setting, and how a working CNA moves up the credential ladder to LPN, RN, or specialty aide work without restarting their career. If you are weighing the path, this article gives you the full picture before you enroll.

Scope of Practice — What CNAs Can and Cannot Do

Scope of practice is the most misunderstood part of the CNA role. A CNA works under the delegated authority of a licensed nurse, usually an RN or LPN. The nurse decides what gets delegated. The CNA performs the task. The legal boundary is set by each state's nurse practice act and by the federal OBRA-87 regulations that govern nursing assistant training in long-term care.

Inside that boundary, a CNA can take vital signs, assist with bathing and grooming, help patients eat, transfer patients from bed to chair, ambulate patients, position and turn bed-bound patients to prevent pressure injuries, empty Foley bags, measure intake and output, collect non-sterile specimens like urine or stool, perform passive range-of-motion exercises, apply non-prescription topical creams when delegated, and document everything in the chart. The CNA II credential, available in about a dozen states including North Carolina, expands scope to include sterile dressing changes, tracheostomy care, ostomy care, and tube-feeding management when delegated by an RN.

What a CNA cannot do is more important to know than what they can. CNAs cannot administer medications in most states, except in the handful that recognize a separate medication aide certification. CNAs cannot start IVs, give injections, draw blood, insert urinary catheters, perform sterile procedures, interpret lab values, or accept verbal physician orders.

CNAs do not assess patients in the clinical sense — they observe and report. If a resident's color changes, breathing changes, or mental status changes, the CNA tells the nurse. The nurse assesses. That distinction is on every state exam, and it is the line that protects both the patient and the CNA's certificate.

Charting matters as much as the bedside work. Every state exam includes documentation questions, and every workplace expects an end-of-shift summary covering vitals, intake, output, meals consumed, toileting, mobility, skin condition, and any incident the nurse needs to know about. The CNA Basic Nursing Skills practice set drills the most-tested documentation scenarios, and the CNA Safety and Emergency Procedures set covers the report-immediately conditions every new CNA needs to recognize.

cna training requirements">CNA Training Requirements — Hours by State and Where to Enroll

Federal OBRA-87 sets the floor at 75 total training hours, with at least 16 of those hours spent in supervised clinical practice in a long-term care facility. Each state then decides whether to require more. About 25 states stick close to the federal floor. The other half layer additional hours, more clinical time, or supplementary topics like dementia care or infection control.

The highest-hour states are Alaska (200), Maine (180), Oregon (175), Virginia (160), California (160), Delaware (150), and Arizona (120). The lowest-hour states are most of the South and the Plains states — Texas, Florida, Georgia, Alabama, Mississippi, Tennessee, Louisiana, Oklahoma, Kansas, Iowa, Missouri, and Indiana all sit at or near the 75-hour federal minimum. North Carolina, South Carolina, and West Virginia use 75 hours. New York requires 100 hours. Massachusetts requires 100. New Hampshire requires 100.

Tuition runs $300 to $1,400 at community colleges, $700 to $1,800 at hospital-sponsored academies, and $1,200 to $2,500 at private schools. The American Red Cross runs accredited programs in many states with tuition closer to the $1,300 to $1,700 range. Most community colleges price under $500 because state funding subsidizes the seat. Wake Tech in North Carolina runs the program for about $340 in tuition plus around $80 in supplies. Central Piedmont, Forsyth Tech, Cape Fear Community College, and Asheville-Buncombe Tech all price similarly.

Many large employers pay you to train. Brookdale Senior Living, Genesis HealthCare, Atrium Health, HCA Healthcare, ProMedica Senior Care, and Encompass Health all run paid CNA academies that recoup tuition through a one-year employment commitment. NCWorks Workforce Development Boards, Workforce Innovation and Opportunity Act (WIOA) grants, and Job Corps programs fund seats for eligible adults in every county. If you are unemployed or underemployed, the funded path is the most common way Americans enter the field.

The CNA Certification Exam — What It Looks Like

Every state requires a competency evaluation administered by an approved testing vendor. The two largest are Pearson VUE and Prometric. Credentia (formerly D&S Diversified) administers the National Nurse Aide Assessment Program (NNAAP) in many states. The exam has two parts — a written or oral knowledge test plus a hands-on skills demonstration. Both must be passed on the same registration to earn the credential.

The written exam is 60 to 100 multiple-choice questions covering physical care skills, role and responsibility of the nurse aide, basic restorative services, mental health and social service needs, spiritual and cultural needs, resident rights, communication, infection control, and safety. Candidates have 90 minutes for the written portion in most states. The passing score sits at 70% to 75% in most states, with some states scaling to a calibrated cut score. Pearson VUE and Prometric both offer an oral version of the written for candidates whose first language is not English or who request reading accommodation.

The skills demonstration is where most candidates feel the pressure. The proctor randomly selects three to five skills from a published list of 22 to 25 skills. Hand hygiene is always tested and must be performed at the start, between resident contact tasks, and at the end.

The other skills typically include making an occupied bed, measuring and recording blood pressure, measuring and recording radial pulse and respirations, transferring a resident with a gait belt, performing passive range of motion on the shoulder or knee, perineal care, mouth care, dressing a resident with an affected side, and feeding a resident with dysphagia precautions.

Each skill must be performed step by step. Skipping hand hygiene, skipping privacy steps like knocking and closing the curtain, or skipping the call light placement at the end of the skill are the most common reasons candidates fail. The skills exam typically lasts 30 to 40 minutes total.

Candidates who fail one of the two parts can usually retake just the failed part — most states allow three attempts within 24 months of completing training. After three failed attempts the candidate retakes the full training program. The CNA Basic Nursing Skills question bank mirrors the written exam format, and the CNA Personal Care Skills set drills the most commonly demonstrated bedside skills.

A Day in the Life — What a 12-Hour Shift Actually Looks Like

A 7 a.m. to 7 p.m. CNA shift on a hospital med-surg floor begins at 6:50 with handoff from the night CNA. Vital signs from the last round, intake and output totals, mobility status, planned procedures, and any overnight changes get passed across. By 7:10 the new CNA is in the first patient's room introducing herself, checking the call light placement, and pulling morning vital signs.

Breakfast trays arrive between 7:30 and 8:30. The CNA assists patients who need feeding help, repositions bed-bound patients, helps ambulate the post-op patients ordered to walk three times daily, and starts the morning bath rotation.

From 9 a.m. to noon the floor moves fast. Physicians round and write orders. Nurses pass medications. The CNA fields call lights, helps patients to and from the bathroom, changes briefs on the incontinent patients, draws fasting blood-sugar fingersticks if certified for that task, and documents intake and output on every patient at every meal.

Mid-morning vital signs run on patients flagged for q4 vitals. Lunch trays arrive at noon. Afternoon brings discharges out, admissions in, and the second round of vital signs. By 3 p.m. the CNA is helping patients up to the chair, walking ambulatory patients, and turning the bed-bound patients to prevent pressure injuries.

The 3 p.m. to 7 p.m. block is the most physical. Dinner trays, evening hygiene, last vitals, and the hand-off documentation. Many hospitals chart in EPIC, Cerner, or Meditech — the CNA documents vitals, I&O, ADLs, bowel movements, repositioning, and any patient-reported pain or symptoms.

Handoff to the night CNA at 6:45 covers the same elements: vitals trend, intake/output, mobility status, skin condition, and any concerns. The shift ends at 7 p.m. but most CNAs stay 15 to 30 minutes finishing cna documents. By the end of the day, a busy CNA has walked 12,000 to 18,000 steps, lifted or transferred patients eight to fifteen times, and documented 100 to 200 individual entries.

Night shifts (7 p.m. to 7 a.m.) trade pace for intensity. Fewer doctors, fewer family visitors, fewer interruptions — but also fewer staff, and the heaviest physical work (turning, repositioning, incontinence care) tends to fall on the night team. Night differential adds $2 to $4 per hour at most hospital systems. The CNA who works three twelves on nights and lives 30 minutes from the hospital can clear $48,000 to $58,000 per year with overtime and differentials, which is competitive with many entry-level office jobs in the same market.

CNA Pay — What You'll Actually Earn

The Bureau of Labor Statistics puts the 2024 median CNA wage at $18.36 per hour or $38,200 per year. State medians range from a low near $14 per hour in Louisiana, Mississippi, Alabama, and Oklahoma to a high near $25 per hour in California, Alaska, Hawaii, New York, and Massachusetts. The District of Columbia leads at $22 per hour median. Hospital CNAs earn 15% to 25% more than skilled-nursing CNAs in the same market. Travel CNAs working contracts earn $25 to $45 per hour including taxable wages plus non-taxable lodging and meal stipends.

Pay rises predictably with experience. A new CNA hired at $15 per hour in 2026 typically reaches $17 to $18 within 18 months and $19 to $22 within five years if they stay with a hospital system. Add a medication aide credential and pay rises another $1 to $2 per hour in the states that recognize it. Add a CNA II credential in North Carolina, Oregon, or other CNA-II states and pay rises $2 to $4 per hour. Specialty units pay differentials — ICU, ED, oncology, and OR typically pay $1 to $3 above general med-surg.

Shift differentials matter more than most new CNAs realize. A weekend Baylor plan, where two 12-hour weekend shifts are paid as full-time with benefits, can clear $24 to $30 per hour effective rate at hospitals like Atrium, Duke, and HCA. Night differential adds $2 to $4 per hour. Weekend differential adds $1 to $3. Holiday pay runs 1.5x or 2x base. A CNA willing to work nights, weekends, and pick up holidays can earn 25% to 35% more than a CNA working straight weekday days at the same base rate. Compare state-by-state numbers in the CNA hourly pay breakdown.

CNA to LPN, CNA to RN — The Credential Ladder

The CNA role is most valuable as a starting point. Roughly 40% of US registered nurses began their career as a CNA before bridging up. The math is simple — a CNA who bridges to LPN typically doubles their hourly rate, from $16-$18 to $26-$32 per hour. A CNA who bridges to RN typically triples it, from $16-$18 to $32-$45 per hour. The bridge programs accept your CNA clinical hours as prerequisite credit and shorten the program by 3 to 6 months.

CNA-to-LPN bridges run 10 to 14 months full-time at community colleges. Tuition runs $5,000 to $12,000 total. Wake Tech, Durham Tech, Central Piedmont, Houston Community College, and Miami Dade College all run respected CNA-to-LPN bridges. The LPN exam is the NCLEX-PN, taken after a 1,500 to 1,800 hour state-approved practical nursing program. LPN scope expands to medication administration, sterile dressings, IV monitoring (not initiation in most states), and supervision of CNAs.

CNA-to-RN bridges run 18 to 24 months full-time. The Associate Degree in Nursing (ADN) is the most common path — a 2-year community college program ending in the NCLEX-RN. Tuition runs $8,000 to $18,000 at community colleges, $20,000 to $40,000 at private schools.

Major hospital systems including Duke Health, UNC Health, Atrium, HCA, and Cleveland Clinic offer tuition reimbursement up to $5,250 per year tax-free to working CNAs enrolled in an ADN program. With reimbursement, a working CNA can complete an ADN with $0 to $5,000 in out-of-pocket debt, then start as a new-grad RN at $30 to $36 per hour.

There are lateral moves too. A CNA can add a medication aide credential (recognized in roughly 25 states) for an extra $1 to $2 per hour. A CNA II credential opens specialty work in NC, OR, AZ, and other CNA-II states. A patient-care technician (PCT) credential, common in hospitals, layers EKG and phlebotomy on top of CNA.

A surgical tech credential is a 12 to 24 month path that ends in OR work at $20 to $30 per hour. The role pivots: many CNAs find their long-term home in hospital telemetry, hospice, pediatric home health, or operating room support before deciding whether to bridge to LPN or RN.

How to Get Hired — The First 90 Days

The job market for CNAs is the friendliest in healthcare. Most large systems run a same-week interview cycle. A new CNA with active state registration, current BLS certification, and a clean background check can be on the floor within 14 days of passing the certification exam. The hiring funnel is short — apply online, brief phone screen, in-person interview (often combined with a working tour of the unit), reference check, drug screen and fingerprint, then orientation. Time-from-application to first paycheck typically runs 10 to 21 days.

The strongest applications hit three points. First, evidence the candidate finished training and passed the exam — copy of the state registry listing plus the exam pass letter. Second, evidence of clinical interest — even a single weekend volunteer at a hospice, hospital, or assisted living shows commitment. Third, evidence of dependability — references from past employers (any past employer, not just healthcare) attesting to attendance and reliability. CNAs are hired or not hired primarily on dependability. The technical skills come back fast in orientation; the dependability does not.

For where to apply, hospital careers pages have the highest pay but the slowest hiring cycle (often 2-3 weeks). Indeed and Glassdoor list SNF and assisted living roles that hire within the same week. Per-diem agencies like Aya Healthcare, Vivian Health, and Krucial Staffing offer flexible scheduling at premium rates once you have one year of bedside experience. State-specific guides like the CNA jobs in North Carolina breakdown list the major employers, pay ranges, and hiring timelines for that state's largest systems.

Negotiation is possible even at entry level. Sign-on bonuses run $500 to $5,000 at hospital systems and SNFs that struggle to staff. Shift differential is rarely negotiable but the choice of shift usually is — if you can offer night and weekend availability, you can almost always pick the unit. Tuition reimbursement is the single most valuable benefit and most candidates forget to ask about it. Confirm in writing what percentage is reimbursed, the annual cap, and the clawback period if you leave the employer.

Final Take — Is the CNA Path Right for You

The CNA career fits a specific kind of person. If you want fast credentialing, real patient contact, a clear ladder up, and you can handle the physical and emotional demand of bedside work, this is one of the best entry points in American healthcare. If you want a desk job, slow pace, or strict 9-to-5 hours, the role will burn you out within a year. Honesty about fit matters — the CNAs who stay love the work, not the paycheck.

The credential is portable. You can earn it in California and move to North Carolina with a reciprocity application. You can move from SNF to hospital after twelve months of experience. You can bridge to LPN in just over a year, or RN in just over two. The path scales with effort — the CNAs who plan their career intentionally end up RNs at 22 with no student debt. The CNAs who drift end up making $15 per hour at 35.

The smartest first move is to commit to one full year of bedside work at a setting that runs paid training. Use that year to confirm the path, build clinical hours, and earn tuition reimbursement eligibility. Year two, enroll in either an LPN program or an ADN program while still working part-time. Year three or four, sit the NCLEX. That sequence pays you to train, pays you to bridge, and lands you in a $32-to-$45-per-hour RN role with zero or minimal debt. The CNAs who follow it are the ones who change their family's financial trajectory in a single decade.

Whatever path you choose, certification is the gate. Pass the written and skills exam, get on your state registry, and the door opens. Drill the exam content on the CNA Basic Nursing Skills question bank and the CNA Safety and Emergency Procedures set before your test date. Both mirror the format and content weighting of the NNAAP, Prometric, and Pearson VUE versions of the exam. Pass the exam, take the job, and the rest of the career is yours to build.
