Maryland WIC regulations require that authorized vendors accept training from the WIC Program as required by the Program. Vendors shall have a representative attend and participate in at least one State or local agency interactive training session each calendar year.

Every authorized vendor is required to designate at least one person, to serve as the designated WIC trainer. The designated WIC trainer shall train all cashiers, including pharmacy cashiers and other staff involved with WIC transactions on Program policies and procedures. The vendor or its designated trainer will promptly inform employees of changes in the WIC Program, including changes to the Authorized Foods List.

The Maryland WIC Program offers a variety of Training classes for Vendors. Classes are designed to help stores be successful WIC Vendors.​
