Psychology is a broad field with more than a dozen recognized specialties, each focused on a different slice of human behavior. The American Psychological Association currently recognizes 17 specialties, ranging from clinical psychology to police and public safety psychology. Here’s a breakdown of the major types, what they actually do, and what it takes to become one.
Clinical Psychologists
Clinical psychology is the largest and most recognized specialty. Clinical psychologists assess, diagnose, and treat mental health conditions, including depression, anxiety disorders, schizophrenia, and personality disorders. They work in hospitals, private practices, community mental health centers, and academic settings. Their training emphasizes understanding and treating psychological disturbances, and they typically handle more severe or persistent conditions than some other types of psychologists.
Clinical and counseling psychologists earn a median salary of $95,830 per year, and employment in these roles is projected to grow 11% between 2024 and 2034, faster than most occupations.
Counseling Psychologists
Counseling psychology shares a lot of overlap with clinical psychology, and the two often work side by side in the same settings. The key difference is historical and philosophical: counseling psychology grew out of vocational guidance and has traditionally focused on people without serious or persistent mental illness. Counseling psychologists tend to help clients navigate life transitions, relationship difficulties, stress, and career decisions rather than treating severe psychiatric disorders.
You’ll find counseling psychologists in college counseling centers, independent practices, healthcare settings, organizational consulting groups, and university teaching positions. In practice, the line between clinical and counseling psychology has blurred significantly, and many professionals in both fields perform similar work.
School Psychologists
School psychologists work primarily with children and adolescents in K-12 settings. Their responsibilities include administering cognitive and achievement tests (like IQ assessments), counseling students, planning academic or behavioral interventions, and consulting with teachers and parents. Most states require school psychologists to hold a specific certification to deliver services through a school system.
School psychologists earn a median salary of $86,930. Job growth in this area is projected at just 1% over the next decade, making it one of the slower-growing psychology specialties.
Educational Psychologists
Educational psychologists are a related but distinct group. They study how people learn, covering topics like motivation, development, assessment, and instruction across all ages and settings, not just schools. Their work is primarily research-oriented. Most educational psychologists become professors or researchers at universities rather than working directly with students. They don’t hold clinical duties but often train future teachers by teaching courses on learning theory and classroom assessment.
Industrial-Organizational Psychologists
Industrial-organizational (I-O) psychologists apply behavioral science to the workplace. They help companies improve employee productivity, develop hiring and screening procedures, resolve workplace conflicts, and build better management structures. Their research spans a wide range of topics: leadership development, compensation, workplace safety, team dynamics, diversity, and work-life balance.
This specialty is one of the highest-paying in psychology, with a median salary of $109,840. I-O psychologists work in corporate offices, consulting firms, government agencies, and research settings. Projected job growth sits at 6% through 2034.
Forensic Psychologists
Forensic psychologists operate at the intersection of psychology and the legal system. They conduct evaluations that directly shape legal decisions: determining whether a defendant is competent to stand trial, assessing whether a suspect understood right from wrong at the time of a crime, or evaluating the psychological impact of injuries in personal injury lawsuits. They also work on child custody cases and child abuse investigations.
Some forensic psychologists specialize in threat assessment, predicting who may be at risk of committing a violent act. Others help attorneys with jury selection or run focus groups to test which legal arguments are most persuasive. Their testimony in court carries significant weight because they bring psychological evidence into proceedings where judges and juries need expert guidance.
Clinical Neuropsychologists
Neuropsychologists specialize in the relationship between the brain and behavior. When someone has a brain injury, stroke, neurodegenerative disease, or other condition affecting cognition, a neuropsychologist evaluates what’s changed. They use structured testing to measure specific abilities: memory, attention, planning, problem-solving, language, and processing speed.
These evaluations help determine the severity of cognitive impairment, track changes over time, and guide treatment or rehabilitation plans. Neuropsychologists work in hospitals, rehabilitation centers, and private practices, and they frequently collaborate with neurologists and other medical specialists.
Health Psychologists
Clinical health psychologists focus on how psychological factors influence physical health and illness. They help patients manage chronic conditions like diabetes, heart disease, or chronic pain by addressing the behavioral and emotional components of those conditions. This might involve helping someone stick to a treatment plan, manage stress that worsens symptoms, or change habits like smoking or poor diet. They typically work in hospitals, medical clinics, and rehabilitation centers.
Sports Psychologists
Sports psychologists work with athletes and teams to address the mental side of performance. A basketball player might have excellent technique but hesitate to take open shots. A sports psychologist helps identify the thought patterns, automatic beliefs, or psychological blocks behind that kind of gap between ability and performance.
Their toolkit includes visualization and mental rehearsal, stress management, relaxation techniques, positive self-talk strategies, and confidence-building. They also handle clinical concerns like anxiety and depression in athletes. Sports psychologists provide individual counseling, run team-level interventions, and consult with coaches and athletic trainers on broader support strategies.
Other Recognized Specialties
Several other APA-recognized specialties serve more specific populations or settings:
- Geropsychologists specialize in the mental health and cognitive needs of older adults, including dementia-related care and adjustment to aging.
- Rehabilitation psychologists help people adapt to disabilities, chronic illness, or injuries, often working alongside physical and occupational therapists.
- Couple and family psychologists treat relationship dynamics and family systems rather than focusing exclusively on individuals.
- Police and public safety psychologists support law enforcement and first responders through fitness-for-duty evaluations, crisis intervention, and resilience training.
- Psychoanalytic and psychodynamic psychologists use therapy approaches rooted in exploring unconscious processes, early life experiences, and patterns in relationships.
PhD vs. PsyD: Two Paths to Practice
Most practicing psychologists hold a doctoral degree, but there are two main routes. A PhD in psychology is a research-oriented degree. Students spend significant time conducting original research, and many go on to careers in academia or research-heavy clinical roles. A PsyD (Doctor of Psychology) was developed as a practitioner-focused alternative, modeled loosely after the medical degree. PsyD students still receive research training but spend more time on clinical technique and applied work.
The PsyD has grown substantially in popularity, and both degrees lead to licensure and independent practice. That said, some bias against the PsyD persists in parts of the profession, partly because the degree became associated with for-profit professional schools of varying quality. Graduates of well-regarded PsyD programs, however, are fully competitive in the job market.
Nontraditional Psychology Careers
Not every psychology graduate works in a therapy office or a university. A growing number apply behavioral science training in fields like user experience (UX) research, where understanding how people think and make decisions is central to designing apps, websites, and products. Others work in marketing, public policy, data analytics, and human resources. The core skill set of psychology, understanding why people behave the way they do, transfers to nearly any industry where human decision-making matters.
