"What Do All Those Letters Mean?" Understanding Mental Health Credentials in Illinois
- Jul 18
- 5 min read
If you've ever searched for a therapist, you've probably noticed a variety of letters after people's names:
P.S. Scroll to the bottom of this post for a picture of this information!
LPC. LCPC. LSW. LCSW. LMFT. PsyD. PhD. APRN. Psychiatrist.
It can quickly become overwhelming.
Many people wonder...
What's the difference?
Are some therapists more qualified than others?
The good news is that these professionals all share the same goal: helping people improve their mental health and well-being. While each profession has its own educational path, licensing requirements, and areas of specialization, all licensed mental health professionals have completed extensive training and are regulated by the State of Illinois.
Let's break down what these titles actually mean. Click on the titles to learn more!
Graduate Student/Intern/Practicum Student
You may encounter therapists who are completing graduate school through supervised internships.
Graduate counseling interns are master's-level students who provide counseling while receiving close supervision from experienced licensed clinicians.
Working with an intern can offer several benefits:
Lower-cost services
Fresh knowledge of current research
Close supervision and consultation
High levels of dedication and preparation
Many clients have meaningful and lasting therapeutic experiences with counseling interns.
Licensed Clinical Professional Counselor (LCPC)
An LCPC is an experienced professional counselor who has completed:
A master's degree in counseling
Thousands of hours of supervised clinical experience
A national licensing examination
Additional state licensing requirements
LCPCs can independently diagnose and treat mental health conditions, provide psychotherapy, develop treatment plans, and often supervise other counselors pursuing licensure.
Licensed Social Worker (LSW)
An LSW earns either a bachelor's or master's degree in social work and becomes licensed through the state.
Social workers are trained not only in mental health but also in understanding how family systems, communities, social environments, and available resources impact a person's well-being.
Many LSWs work in:
Schools
Hospitals
Medical settings
Community agencies
Case management
Behavioral health
Some also provide therapy under supervision depending on their education and workplace.
Licensed Clinical Social Worker (LCSW)
An LCSW is a master's-level social worker who has completed advanced supervised clinical experience and passed a clinical licensing examination.
Like an LCPC, an LCSW can independently provide psychotherapy, diagnose mental health conditions, and treat emotional and behavioral concerns.
LCSWs often integrate an understanding of both mental health and environmental factors such as family dynamics, community supports, financial stressors, and systems that affect daily life.
Licensed Marriage and Family Therapist (LMFT)
An LMFT specializes in relationships and family systems.
Their graduate education emphasizes:
Couples counseling
Marriage therapy
Family dynamics
Parenting
Communication
Relationship conflict
Although many LMFTs also work with individuals, they receive specialized training in understanding how relationships influence emotional well-being.
Now things start to get a bit different...
Psychologist (PhD or PsyD)
Psychologists earn doctoral degrees in psychology.
You may see:
PhD (Doctor of Philosophy in Psychology)
PsyD (Doctor of Psychology)
Psychologists provide psychotherapy, psychological evaluations, cognitive testing, personality assessments, and other specialized assessments.
In Illinois, psychologists generally do not prescribe medication.
Psychiatrist (MD or DO)
A psychiatrist is a medical doctor who specializes in mental health.
Because they attend medical school, psychiatrists can:
Diagnose mental health disorders
Prescribe medication
Monitor psychiatric medications
Treat complex psychiatric conditions
Some psychiatrists also provide therapy, although many primarily focus on medication management while collaborating with therapists.
Psychiatric Mental Health Nurse Practitioner (PMHNP)
A Psychiatric Mental Health Nurse Practitioner (PMHNP) is an advanced practice registered nurse with specialized graduate education in psychiatric care.
PMHNPs can:
Diagnose mental health conditions
Prescribe psychiatric medications
Monitor medication effectiveness
Provide psychotherapy (depending on training and practice setting)
Many work alongside therapists as part of a collaborative treatment team.
So...Who Is the "Best" Therapist?
One of the biggest misconceptions is that one license is inherently better than another.
In reality, the quality of therapy often depends less on the letters after someone's name and more on factors such as...
The relationship you build with your therapist
Their experience treating your concerns
Their therapeutic approach
Your comfort level
Their ability to understand your goals
Research consistently shows that the therapeutic relationship is one of the strongest predictors of successful outcomes in therapy.
Credentials matter—but finding the right fit matters just as much.
Which Professional Should You Choose?
Different professionals may be a better fit depending on your needs.
You might consider:
An Intern or Graduate Student, LPC, LCPC, LSW, LCSW if you are looking for:
Anxiety treatment
Depression treatment
Trauma therapy
Stress management
Individual counseling
Family therapy
Any of the above or more specifically, a LMFT if your primary concerns involve:
Couples counseling
Marriage difficulties
Parenting challenges
Family conflict
A Psychologist if you need:
Psychological testing
ADHD evaluations
Autism assessments
Learning disability evaluations
Comprehensive diagnostic assessments
A Psychiatrist or PMHNP if you are seeking:
Medication evaluation
Medication management
Treatment for more complex psychiatric conditions
Ultimately...
Choosing a therapist doesn't have to feel overwhelming.
While credentials are important, they are only one piece of the puzzle. Every licensed mental health professional in Illinois has completed rigorous education, training, supervision, and state licensing requirements.
Rather than focusing solely on the letters after someone's name, consider asking questions like:
Do I feel comfortable talking with this person?
Do they have experience with my concerns?
Do I feel heard, respected, and understood?
At the end of the day, the right therapist is someone who helps you feel safe, supported, and empowered as you work toward your goals.

There are often more credentials behind someone's name, like mine! Here's what mine stand for...
Professional Educator (PEL)
A Professional Educator License (PEL) is an Illinois credential issued to qualified education professionals who meet state requirements for working in public schools. Depending on the endorsements held, a PEL may qualify someone to work as a teacher, school counselor, school social worker, school psychologist, administrator, or in other educational roles. A PEL reflects specialized preparation and experience within the education system, but it is not itself a mental health counseling license.
For someone who holds both an LCPC and PEL, the combination can be especially valuable when working with children, adolescents, parents, educators, or schools because it reflects professional training across both mental health and education.
National Certified Counselor (NCC)
An NCC (National Certified Counselor) is a voluntary national certification awarded by the National Board for Certified Counselors (NBCC). Counselors who earn the NCC have met national standards related to graduate-level counseling education, examination, and professional requirements.
Unlike an LCPC, which is a state license that authorizes someone to practice clinical counseling in Illinois, the NCC is a national professional certification. It demonstrates that a counselor has chosen to meet standards established by a national credentialing organization in addition to any state licensure they hold.
