There are two types of food managers certifications; STANDARD and LIMITED. Which one you get will depend on what kind of work you do.
STANDARD Food Manager certifications are required for most facilities which prepare and serve food (including restaurants, bars, cafeterias, markets, food trucks, bakeries, and food stands). You must pass an ANSI-ANAB Food Protection Manager Certification Exam to earn the STANDARD Food Manager Certification. All restaurants and foodservice establishments which are not classified as LIMITED by their local Health Department are required to have at least one person on premise during all operating hours, day and night, who holds a valid STANDARD Food Protection Manager’s Certification and serves as the "Person in Charge" (PIC), and can produce either a copy of their original Food Protection Manager Certification or a Northern Virginia Certified Food Manager (NVCFM) Photo ID Card / Certificate issued by ORS Interactive.

LIMITED Food Manager Photo ID Cards / Certificates are required for facilities defined as “those which typically serve hotdogs, prepackaged foods, or other types of food that are not potentially hazardous.” You must pass a LIMITED Food Protection Manager Certification Exam at ORS Interactive's Training and Testing Facility to qualify a LIMITED Food Manager Certification.
It is the responsibility of each person applying for a STANDARD Northern Virginia Certified Food Manager (NVCFM) Card or a LIMITED Northern Virginia Certified Food Manager (NVCFM) Card to know the correct classification of their licensed food establishment. Those who are uncertain of their establishment’s classification should contact their local Health Department before making application for a Northern Virginia Certified Food Manager (NVCFM) Photo ID Card / Certificate.
