Yes, there are timed practice tests available on the SkillTracker platform at www.td.org/skilltracker. From that page choose Start Now or Return to Your Assessment, provide your TD.org credentials and then select ATD Practice Tests. You will have a choice of the CPLP or APTD practice test. The CPLP practice exam includes 50 questions in 50 minutes. The APTD exam includes 30 questions in 30 minutes. The practice tests are designed to give you an indication of your level of preparation for the exam. A passing score on the practice exam is not a guarantee that you will pass the official exam; however, it will help you to focus your efforts on your weaker areas of expertise.
