Would you like to try the RETA Certification Practice Exam before taking the full exam?

These practice exams are available for you to take as a 'dry run' of the live exam. Get a feel for the actual test experience before you take the full CARO, CIRO and CRST exam. The questions come from the question pools of the CARO, CIRO and CRST Exams. All of the questions have been retired from the live exams.

 Note: This is very important, due to the strict security and privacy act compliance effort required for certification, each registrant must have their own unique and viable e-mail address. The system will not allow duplications - so sharing a co-worker's email address will not work.

If you have taken a RETA exam in the past you are in the RETA testing database. Please contact RETA HQ at 541-497-2955 for your login to the Webassessor login page.
