You can select a nonprofit organization where you want to complete your hours, provided it is willing to verify your participation by completing the verification form. In the near future, you will also have the option of getting a direct referral to an existing workfare partner.
If you are looking for a worksite where you can complete the hours assigned to you, you can use the resource guides and websites linked below to help your search. The websites can provide volunteering organizations for you to consider, but it is up to you to confirm that they are accepting volunteers, that they meet your work requirement, and that they can verify your hours completed.

Once you find a location you're interested in, you can sign up online, give them a call, or send an email to ask if they are accepting volunteers. If the organization confirms that they are accepting volunteers, let them know you need them to complete a form that verifies the number of hours completed. When you report to the organization, show them the form that they need to complete to verify your completed hours.
