Which of the following is a benefit of compact state participation?

The benefit of compact state participation primarily lies in enhanced professional mobility for psychologists. This means that when states enter into an interstate compact agreement, licensed professionals, such as psychologists, can practice in multiple member states without needing to apply for separate licenses in each state. This arrangement is particularly beneficial in addressing workforce shortages and facilitating timely access to mental health services across state lines.

Additionally, the compact helps streamline processes, allowing psychologists to provide care in various locations, whether for teletherapy or in-person services, thereby promoting greater flexibility and efficiency in service delivery. This mobility not only aids professionals in their career advancement and opportunities but also serves the public by improving access to psychological care across regions.

The other options relate to limitations or challenges rather than benefits. For example, limited access to licensure, increased paperwork, and uniform education requirements might complicate the practice environment rather than enhance it.
