The answer could be yes, or no, depending on your organizational goals.
The annual self-evaluation is a good tool to use to self-evaluate the progress of your SMS. If you are not an OSHA VPP Star site, you are encouraged to complete the annual self-evaluation at the end of each calendar year to help identify your strengths and weaknesses, devise a plan for moving forward, and promote continuous improvement.
You are required to complete at least one annual self-evaluation prior to submitting an OSHA VPP application. So, if you plan to submit your OSHA VPP application, be sure to complete at least one of these evaluations and include it with your OSHA VPP application (you can do it yourself—use a group effort).
If you are not looking to apply for formal OSHA VPP recognition, an annual self-evaluation is not required. However, it is still encouraged.
