A Licensed Professional Clinical Counselor is an American credential used specifically in states including California, Ohio, Kentucky and Minnesota, and is equivalent in scope to the LPC title used more widely elsewhere in the United States.
What the credential permits
The credential permits independent diagnosis and treatment of mental health conditions, and requires a master's degree in counselling, a defined number of supervised postgraduate clinical hours, and a licensing examination, broadly mirroring the requirements behind the LPC title used in other states.
A difference of title, not of training
As with several related American counselling credentials, the difference between LPCC and LPC lies essentially in the title chosen by a particular state, rather than in any real difference in the underlying training or scope of practice involved. LPCC is an American state-issued credential and does not apply to practice in the UK, where the regulatory landscape for counselling is structured quite differently.
