To take both the Written or Oral Examination and the Skills Evaluation you must pay $95 as of 2015. Normally, your training program will schedule your examination with the Nurse Aide Competency Evaluation Services (NACES) but if you need to schedule your own examination, call NACES at 800-444-5178 or 512-467-0615 for more information or to receive a candidate handbook and application.
The exam is administered by Pearson Vue. You can learn more about the testing process by downloading the Candidate Handbook. You can look for a test site and date in this document: Texas Regional Test Sites and Test Schedules.
