State variations
Where states differ
Mental-health licensing happens at the state level, which produces real differences in title, requirements, and scope across the country.
Title variations for counselors
The same credential is called LPC (Licensed Professional Counselor) in most states, LMHC (Licensed Mental Health Counselor) in New York, Florida, and several others, LCPC (Licensed Clinical Professional Counselor) in Illinois and Maryland, and LPCC (Licensed Professional Clinical Counselor) in California and Ohio. All refer to the same master's-level counseling credential with equivalent scope.
Supervised hours differ
Post-graduate supervised clinical hours vary by state. Most states cluster around 3,000 post-master's hours (California, Texas, and Washington each require 3,000, for example), while some set the bar lower (Oregon requires 2,400). Some states count only direct client contact; others include indirect hours (documentation, supervision, case conferences). The difference can add roughly a year to the path depending on state.
Psychologist prescribing privileges
A small number of states allow psychologists with additional postdoctoral pharmacology training (typically a 2-year master's in psychopharmacology) to prescribe psychotropic medication: New Mexico (since 2002), Louisiana (since 2004), Illinois (since 2014), Iowa (since 2016), Idaho (since 2017), Colorado (since 2023), Utah (since 2024), and Vermont, whose Act 84 of 2026 creates a prescribing-psychologist specialty that requires a collaborating agreement with a psychiatrist before prescribing.
License portability and compacts
The Psychology Interjurisdictional Compact (PSYPACT) allows psychologists to provide teletherapy across participating states, which now include most of the US (psypact.gov keeps the current map). The Counseling Compact, which lets LPCs practice across member states, has been enacted in 40 states (Pennsylvania became the 40th in July 2026); 11 are currently issuing practice privileges (Arizona, Arkansas, Georgia, Indiana, Louisiana, Minnesota, Missouri, Ohio, Oklahoma, Tennessee, and Wyoming, after Missouri went live on October 19, 2026), with the remaining states and the District of Columbia still completing the steps to go live. Social workers have their own Social Work Licensure Compact, which has passed its activation threshold but is not yet issuing multistate licenses. These compacts especially affect telehealth providers.
