About the OACCPP

The Ontario Association of Consultants, Counsellors, Psychometrists and Psychotherapists (OACCPP) is a professional association of mental health practitioners that was formed in 1978. 

We're proud to serve over 2,300 members throughout Ontario who work in a variety of settings, such as community clinics, family health teams, hospitals, colleges, school boards, private practice settings, EAP programmes and other mental health related services. About 60% of our members are in private practice.


The OACCPP is an incorporated provincial body of mental health service providers with a mandate to provide for the professional needs of our members, and to meet the needs of the community in identifying and certifying competent practitioners providing services in mental health consulting, counselling, psychometry, and psychotherapy.

OACCPP Certification recognizes knowledge, skills and aptitude of mental health professionals, emphasizing competence and expertise in their provision of services.


The OACCPP works tirelessly to provide our members with engaging and effective professional development opportunities; while monitoring and proactively responding to issues within the mental health profession that are important to our membership. 

Mental Health Practitioner Designations

As a service to the community, the OACCPP is providing the information below to help outline the differences between counsellors, consultants, psychotherapists and psychometrists. 




A professional whose practice involves the primary function of informing, advising, guiding, educating, and coaching. The practice of counselling includes, but is not limited to, clinical, and mental health counselling. Incorporated in its mandate is guidance and education to individuals, families and/or groups.



Any person who provides consulting services in the form of education and information to individual professionals, groups or organizations in the public or private sector.



Psychotherapists work with individuals, couples, families and groups to help them overcome a range of psychological and emotional issues. Psychotherapists use personal treatment plans and a variety of non-medical-based treatments to help them solve specific problems; or to treat mood disorders such as depression, OCD and anxiety.

Using talk therapy, they provide insight and use psychotherapeutic interventions to change distressing patterns of cognitions or behaviours that contribute to mood, anxiety or other problems. Some examples of the different approaches psychotherapists use are behavioural therapy, cognitive-behavioural therapy, and gestalt therapy. They commonly work in rehabilitation centres, multidisciplinary health clinics, psychological offices and in private practice. Although Psychotherapists may treat people with clinical diagnoses (e.g., Major Depression, OCD, General Anxiety Disorder) with psychotherapy (talk therapy), they are not licensed to provide a diagnosis or prescribe medication.

In Ontario, only members of the College of Registered Psychotherapists of Ontario (CRPO) have the authority to identify themselves as Registered Psychotherapists (RPs).



Psychometrists are part of research or healthcare teams that specialize in administering, scoring, analyzing and interpreting psychological tests. In Ontario, Psychometrists are not legally allowed to communicate diagnoses, so they must work under the supervision of a Registered Psychologist or Psychological Associate, who are licensed to do so. Tasks include explaining testing procedures to clients, answering questions, administering tests, scoring tests, analyzing data, interpreting results, writing reports and communicating results to other mental health care professionals. A psychometrist must also stay up to date with new developments in the field, as tests and procedures are created, updated and/or improved.
