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 range from 2,000 (states such as Oregon and Washington) to 4,000 (states such as California and Texas). Some states count only direct client contact; others include indirect hours (documentation, supervision, case conferences). The difference can add 1 to 2 years to the path depending on state.
Psychologist prescribing privileges
Seven states currently 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), and Utah (since 2024). About a dozen more states have active legislative efforts to expand the same scope.
License portability and compacts
The Psychology Interjurisdictional Compact (PSYPACT) allows psychologists to provide teletherapy across participating states (40 states plus the District of Columbia effective as of 2026). The Counseling Compact, which lets LPCs practice across member states, has been enacted in 40 states (Pennsylvania became the 40th in July 2026); six are currently issuing practice privileges (Arizona, Georgia, Indiana, Louisiana, Minnesota, and Ohio), with the remaining states and the District of Columbia still completing the steps to go live. LCSWs are working toward a similar interstate compact. These compacts especially affect telehealth providers.
