The easiest CNA jobs are usually in long-term care assisted living facilities or home health care, where patient needs are more routine and the pace is slower compared to hospitals or nursing homes.

Most CNA written exams have 60–70 questions, and you need about 70–80% correct to pass. That means you can usually miss 12–18 questions, depending on your state’s scoring.

If you fail, you can retake the exam up to three times within 24 months of finishing your training. After three failed attempts, most states require you to redo CNA training before testing again.

The most common mistake is missing critical steps, like proper handwashing, patient safety, or positioning.
