Which document must be available for M7?

The correct response highlights the importance of having certified documentation of the PATH credentialed individual(s) involved. This requirement ensures that all personnel providing services meet the necessary qualifications and have been properly vetted through PATH International's rigorous credentials. Such certification serves as validation of their skills, training, and adherence to the ethical standards set by the organization, which is critical for maintaining safety and quality in therapeutic environments.

In contrast, while the other options may provide valuable information for operational or administrative purposes, they do not directly address the core requirement for M7. Documents detailing client interactions, annual activity reports, and lists of therapy equipment serve different functions in program oversight and accountability, but the primary focus for M7 is on verifying the credentials of the individuals delivering therapy.
