Which credential is specifically referred to as an active credential for psychologists in compact states?

The correct answer is the "E-passport." This credential functions within the context of compact states, facilitating psychologists in providing services across state lines. The E-passport serves as a streamlined verification process indicating that the psychologist meets the necessary qualifications established by the compact agreement, and allows for the practice of telepsychology under specific regulations.

This credential is distinct as it enables psychologists to maintain an active status across multiple states within the compact, thereby enhancing their ability to deliver services while adhering to the stipulations set forth by the compact. The E-passport represents a significant advancement in telehealth and inter-state practice, aligning with the evolving landscape of regulatory practices in psychology.

Other options, while relevant in terms of credentials and licenses, do not specifically refer to the mechanism or credential described as “active” in compact states. Each of them may pertain to license provisions or specific regional requirements but does not encapsulate the overarching utility and definition that the E-passport serves in the context of the interstate compact for psychologists.
