The Project Management Institute created the PMI-ACP (Agile Certified Practitioner) in 2011 to establish credentials for someone who has been adequately trained with how to implement the Scrum Framework. Scrum was one of the original Agile methodologies and remains by far the most popular today.
The PMI-ACP is a combination of everything you'd learn in a Certified Scrum Master class, and everything you'd lear in a Certified Product Owner class, along with advanced Risk Management techniques, some Lean concepts applicable to software development, and a few extra accessories that help Scrum scale up for larger projects, and larger group sizes.
In addition, PMI requires at least nine months of actual experience working with a Scrum team before they will aware the credential.
If you are an HR Professional, rest assured your candidate presenting with a PMI-ACP certification is slightly better equipped than one with a Scrum Master, or Product Owner, or both.
