What does ABC certified mean?

"ABC certified" doesn't have a single, universally recognized meaning. The letters ABC could refer to many different organizations or certification programs depending on the context. To know what "ABC certified" means, you need more information, such as:

* The industry: Is it related to construction, healthcare, education, a specific trade, etc.?

* The specific area: What is being certified? (e.g., a person, a product, a business practice)

* The full name or any other identifying information: Is there a longer name associated with the certification (e.g., "ABC Safety Certification")?

Without more context, it's impossible to say what "ABC certified" signifies.
