There are 11 measures of store nutrition environments which assess the availability and pricing differences between healthier and less-healthy options: milk, fresh fruits and vegetables, ground beef, hot dogs, frozen dinners, baked goods, beverages (soda/juice), whole grain bread, baked chips, and cereal.
The NEMS-S tool has been updated since its original publication. The original published version of the instructions and the store measures can be accessed by clicking on this link: NEMS-S survey and instructions.
The updated version of the NEMS-S tool has an added measure of cereal as well as some changes to the layout.
