A seal of approval is a mark or symbol that indicates that a product, service, or organization has been evaluated and found to meet a certain standard of quality or safety. It’s a stamp of trust that says to people, “This product/service has passed the test.”

For example, if you notice an Energy Star rating on an appliance, it means that the product has met the latest energy efficiency requirement and is certified by a government agency. Similarly, if you see USDA Organic on a food package, then you know that the food has been through intensive standards to make sure that the way it is grown and handled is safe.

Seals of approval give consumers confidence. When you buy something that has an official seal on it, you know that it has been evaluated by experts and measures up to some standard. They are also a boon to businesses, as these seals are used as an advertisement to respect and attract customers whose losses would be sustained if they experience anything less than the best of quality and safety.

A seal of approval can be awarded by a wide variety of organizations, government organizations, professional organizations, or independent testing entities. Whatever the source, it tells us the same thing in every case: We know this is true.

(In short, a seal of approval is not a mere badge.) It’s a guarantee of assured reliability and a quality guarantee between the manufacturer and buyer.
