Prometric does not offer free online CNA practice exams, but other companies such as CNAOnline and CNA Thrive do offer free practice exams that cover the material on the CNA exam administered by Prometric. Prometric offers only paid CNA practice exams with different fees for different practice with the written and skills parts of the computer-based exam.
CNAOnline notes that taking free practice tests can help CNA students save money by better preparing them to pass the actual exam on the first attempt. Free practice exams on this site provide students with explanations of mistakes to help target addition study. The site provides links to practice exams for different states along with connecting to information and tips about how to study and pass the exam. Additionally, the site is regularly updated with new material to include any changes on the CNA exam, as of 2015.
CNA Thrive offers free practices exams that cover nine different areas including tests of CNA daily duties, data collection and patient safety. The content of the actual exam and practice tests follow the curriculum generally outlined in commonly used CNC training textbooks. Once a test-taker has worked through the free sample tests, the company encourages additional preparation with full-length practice exams, solutions and feedback for a fee.
