A psychological assessment is a structured, evidence-based process applied by a qualified psychologist to understand a person’s psychological functioning and answer specific questions clearly and reliably. The purpose is to inform legal decision-making, clarify mental health or cognitive difficulties, assess vulnerability or risk, or provide recommendations to support wellbeing.
At Compass, psychological assessments are carried out with professionalism, compassion and respect. Our psychologists use research evidence and clinical understanding as well as our ability to engage with a wide range of individuals across the lifespan to produce clear, accessible reports grounded in robust psychological evidence.
Why Would Someone Need a Psychological Assessment?
Psychological assessments are often used when decisions need to be made using independent, clinically informed evidence. In legal contexts, assessments can help the Court understand complex psychological issues and reach fair, well-informed conclusions. An assessment may also be required to clarify the nature and severity of difficulties, explore the impact of trauma, or understand a person’s cognitive functioning or vulnerabilities.
Depending on the referral question, a report may address topics such as:
- Mental health
- Cognitive functioning
- Capacity, risk and vulnerability
- Parenting, attachment or relationship dynamics
- The psychological impact of specific events or experiences (trauma and adjustment)
Who Can Carry Out a Psychological Assessment?
A psychological assessment should be completed by a suitably qualified applied Psychologist (e.g., Clinical, Forensic and Educational Psychologists). Compass assessments are delivered by HCPC-registered applied Psychologists, and all assessments are conducted in line with ethical standards and professional guidelines issued by the Health and Care Professions Council (HCPC) and British Psychological Society (BPS).
What Does a Psychological Assessment Involve?
At Compass, our psychologists use a structured yet flexible approach that integrates clinical interviews, psychometric testing and an analysis of background records, which then leads to a psychological formulation. This builds a clear picture of the person’s strengths, vulnerabilities and psychological needs.
The assessment process typically includes:
- Referral and instruction – agreeing the scope of the assessment, reviewing the key questions, and receiving relevant documentation from the legal representative or commissioning party.
- Document review – analysing background information such as medical or legal records (and, where relevant, previous assessments).
- Clinical interview – a structured but supportive conversation exploring history, experiences and current presentation (in person, online, or in custodial settings if required).
- Psychometric testing – where appropriate, administering standardised measures to assess areas such as intellectual functioning, memory, trauma, mood, personality, or risk factors.
- Formulation and report – integrating all information into a comprehensive, evidence-based report that answers the instructing questions and provides a clear psychological formulation.
Reports are written in accessible, professional language and include relevant conclusions and recommendations.
What Are Psychometric Tests (and Why Are They Used)?
Psychometric tests are standardised measurement tools of various psychological factors. The tools used will depend on the person’s age, capacity, background, and the purpose of the assessment.
Examples of psychometric tools may include:
- WAIS-IV / WISC-V – assessment of intellectual functioning
- BDI-II / BAI – measures of anxiety and depression
- TSI-2 – trauma and PTSD assessment
- WMS-IV – memory screening / memory functioning
- MCMI-III – personality and clinical profile measures
- HCR-20 / RSVP / SARA – structured professional judgement tools for risk assessment
- TSCC / TSCYC – trauma and post-traumatic stress measures for children
- BYI – child anxiety and depression inventories
- SAVRY – violence risk assessment (young people)
What Might the Outcome of a Psychological Assessment Be?
Outcomes will vary depending on the referral question and context. A report might clarify the nature and severity of mental health difficulties, assess cognitive or memory impairments, identify psychological vulnerabilities, or provide a structured opinion relevant to legal decision-making.
Examples of outcomes may include:
- Clarifying the nature and severity of psychological difficulties
- Assessing cognitive or memory impairments affecting daily functioning
- Providing insight into personality factors influencing behaviour, emotional control, decision making and relationship functioning
- Identifying psychological vulnerabilities relevant to legal or occupational contexts
- Evaluating capacity (for example, capacity to instruct a Solicitor) or fitness to plead
- Evaluating risk of harm or other risk-related concerns
- Offering treatment or support recommendations
Every report includes a clear psychological formulation explaining how the person’s experiences and traits interact to shape their current presentation.
How Long Does a Psychological Assessment Take?
Timescales depend on the complexity of the referral and the availability of relevant documents. Many assessments involve one or two interview sessions (often 1–3 hours each), with additional time for testing where required. Clear timelines are typically agreed at instruction, with communication maintained throughout the process.
Psychological Assessments for Court, Adults, and Children
“Psychological assessment” is an umbrella term, and the focus and process will be adapted depending on who the assessment is for and what questions need answering.
Psychological Assessments for Court
In court proceedings, assessments provide an independent expert opinion to assist the Court. Reports may address matters across Family, Criminal and Civil Courts, including topics such as parenting capacity, children’s psychological wellbeing, trauma evaluation, risk, capacity, fitness to plead, and the psychological impact of injury or offence.

Psychological Assessments for Adults
Adult psychological assessments can be suitable for individuals involved in legal proceedings, including Civil, Family and Criminal Courts. Depending on the referral, the assessment may explore mental health, trauma, mood, personality, cognition, memory, and other vulnerabilities relevant to the questions being asked.

Psychological Assessments for Children and Young People
Child and adolescent assessments are tailored to the young person’s developmental stage, communication style and circumstances. They may involve interviews and observations with the child and caregivers, consultation with professionals where appropriate, and age-appropriate psychometric testing. The aim is to understand the child’s experiences in context and provide recommendations that support wellbeing and development.
