Social Work Methods · Casework
Every helping relationship in social casework follows a path. It begins with a client who is stuck and ends with a client who is standing on their own. This guide walks that path in five clear phases, with examples, charts and a worked case.
The 5 phases of social casework at a glance
The five phases of the social casework process are (1) social investigation or study, (2) assessment or social diagnosis, (3) intervention or treatment, (4) termination and follow-up, and (5) evaluation. Mary Richmond (1917) first described three phases, namely investigation, diagnosis and treatment. Contemporary practice splits these into five.
- 1Social studyGather the facts about the person and the problem
- 2AssessmentMake sense of the facts and name the problem
- 3InterventionPlan and carry out the help, together with the client
- 4Termination and follow-upEnd the relationship gradually and check back
- 5EvaluationJudge whether the goals were met

Before the phases
What is social casework?
Social casework is a method of social work that looks at both the individual and the environment. Its aim is to improve the balance between what the person can cope with and what life demands of them. Sometimes people cannot solve a problem or reach the help that already exists, because of causes inside them or around them. A caseworker then uses the skills, techniques and methods of casework to help the client solve their psycho-social problems and cope better with social functioning.
Think of the five phases as threads in one weave. They are not sealed rooms. Study continues while you assess, and evaluation runs quietly through the whole process, not only at the end.

Phase 1
Social investigation (social study)
Social investigation is a systematic study of the client and their circumstances in relation to the problem. Other names for this phase include social evidence, social inquiry, intake and orientation.
Mary Richmond stressed that the caseworker must collect all the facts and reason from them carefully, because this reveals the client's personality and situation and makes proper treatment possible. Every later activity rests on this foundation, whether you work with an individual, a family, a community or society.
What the study must cover
Social investigation exists to answer three questions: What exactly is the problem? What caused it? What can be done? According to Perlman, the first phase looks at six things:
- The nature of the presenting problem
- The significance of the problem to the client
- The cause, onset and precipitating factors
- Efforts the client has already made to cope
- The solution or goal the client wants from the agency
- The agency's own character and ways of helping, in relation to this client
Perlman's four working methods for the opening phase
- Give the client something to do. Even a small task builds involvement.
- Help the client talk through the problem. Listening comes before advising.
- Partialize and focus. Break a tangled situation into workable pieces.
- Connect the client with the agency. Explain what help is and is not available.
Tools and techniques of the case study
- 🗣️Interview
- 👀Objective observation
- 📝Records and documents
- 📚Secondary sources
- 👨👩👧Family members
- 🧪Special tests
The interview is the engine of social investigation. It collects information about the client, their difficulties and their relationships. It also lets the worker guide the client and the key people around them. Good interviewing needs more than textbook knowledge of human behaviour. It needs supervised practice.
What information to collect
- The present problem and its origins: when, how and where it began, what was tried, and how things stand now.
- The client's background: developmental and health history, school or work progress, traumatic events or disabilities, family profile, cultural and economic status, important relationships, interests and abilities.
- The environment: how the surroundings affect the client, and how the client affects them.
Example. A mother says her 14-year-old son stopped going to school. The caseworker interviews the mother, speaks with the boy separately, checks attendance records and talks to a teacher. Only then does the picture of when and why it started begin to form.
Phase 2
Assessment (social diagnosis)
Assessment is the thinking phase. The caseworker uses the facts, together with their knowledge of human behaviour and social realities, to work out what the client's problem is, what contributes to it, what could reduce it, and what steps the caseworker can take. The aim is to come as close as possible to an accurate picture of the client's social position and personality.
A good assessment has two qualities:
- It is grounded in known facts, both tangible facts and psychological facts.
- It is open to revision. The worker keeps other plausible explanations in mind and changes the assessment when new information arrives.
Three types of diagnosis
- Dynamic diagnosis explains the present problem and the forces at work inside the client, in their social setting, and between the two. It asks: What is the problem? Which psychological, physical and social factors play a part? What resources exist? It stays flexible because it is formed early.
- Clinical diagnosis classifies the client by the nature of their condition and identifies dysfunctional features of behaviour or personality. It is useful when a personality difficulty clearly exists alongside the social problem and feeds it.
- Etiological diagnosis looks for the origins of the problem. The client's developmental history can show what they are going through and how far they are likely to cope. It is especially helpful when the client's reactions seem inconsistent with the present problem.
Four steps when diagnosing
- Notice undesirable behaviours. Survey functional and dysfunctional behaviour in the client and the environment, framed as excesses or deficiencies.
- Focus on defined behaviours. Break complex behaviour into smaller pieces.
- Collect baseline data to see what seems to control the problem behaviour now.
- Analyse the data to predict likely difficulties and start setting intervention goals.
Tip for exams: "Assessment" and "social diagnosis" name the same phase in most textbooks. "Diagnosis" is Richmond's older word. "Assessment" is the modern one.
Phase 3
Intervention (treatment)
Intervention aims to relieve the client's distress and restore, maintain or strengthen their social functioning. It also builds comfort, satisfaction and self-awareness, and may strengthen the ego's coping abilities and the working of the person-situation system. Hamilton described treatment as everything done to help a person with a problem. The focus is the immediate problem first and, where possible, the deeper difficulties behind it.
The ten stages inside intervention
- Initial phase
- Motivation and role induction
- The primary contract
- Diagnosis and assessment
- Setting intervention goals
- Developing an intervention plan
- Preparing for actual intervention
- Intervention in practice
- Monitoring and evaluating the effects
- Planning follow-up and termination
Three ways of intervening
Direct method
The worker influences the client directly through counselling and structured support. It suits clients who need direction because of lack of knowledge, anxiety or limited ego strength.
Environmental modification
The worker changes the client's surroundings to reduce stress, and influences the attitudes of parents, teachers, spouses, employers and relatives. Services such as home help, camps, group activities and training for self-reliance belong here.
Practical service
The worker helps the client choose and use community resources: money, medical care, day care, scholarships, foster homes, legal aid, recreation. Hamilton called this the oldest and best-known way of helping, and Porter Lee was the first to classify such resources.
Techniques used in direct intervention
- Building insight: counselling, interviews and clear explanation help clients understand their situation and feelings.
- Supportive interventions: reassurance, suggestions and encouragement give immediate relief and motivation.
- Behaviour modification: methods such as positive reinforcement support healthier habits.
- Strengthening relationships: family counselling or communication skills training improve how clients interact.
- Clarifying the situation: filling gaps in what clients know about themselves or their surroundings.
- Understanding emotions: helping clients see a situation more objectively when strong feelings cloud judgement.
Caseworkers change the environment only when the pressure on the client is beyond the client's control but within the caseworker's reach. Otherwise, the client stays the main actor.
Phase 4
Termination and follow-up
Termination ends the process that began when the client agreed to casework help. Worker and client decide the ending together, once the worker is confident the client can handle present and future difficulties. An abrupt ending is neither wise nor necessary.
The better path is gradual. Contacts become fewer and further apart so that the client's dependence on the worker fades naturally. Follow-up is planned on a tapering schedule: two weeks, one month, three months, six months and one year.
Why taper? A sudden exit can feel like abandonment and may undo progress. A planned fade lets the client test new skills while support is still within reach.
Phase 5
Evaluation
Evaluation is the process of judging how well, and how far, the casework process worked. It checks whether the goals set for the case have been met. It gives the caseworker and the client honest feedback on whether the programme is working as planned, whether changes are needed, and whether the client is truly being helped.
A caseworker looks at three things:
- the content and effectiveness of the programme,
- how much stronger the client has become, and
- how well the caseworker helped.
Evaluation is not only a final report. Checking progress throughout lets the worker adjust the plan before small problems grow.
Questions that guide evaluation
- Were the agreed goals reached, fully or in part?
- What does the client say has changed in daily life?
- Which methods helped most, and which did not?
- What should the worker do differently next time?

Putting it together
A worked example: Asha and Ravi
This is a fictional case written to show how the phases connect. Asha, 34, works long shifts. Her son Ravi, 14, has stopped going to school. She approaches a community agency.
- 1. StudyThe worker interviews Asha, then speaks with Ravi alone, checks attendance and talks to a teacher. Ravi's absences began when Asha's shifts changed. He now looks after his younger sister each afternoon. Asha has scolded him and asked a relative, without success.
- 2. AssessmentA dynamic assessment shows pressure from three sides: home duties, falling behind in class, and strained talk between mother and son. Ravi's earlier steady school record points to a situational problem, not a personality difficulty, so no clinical label is needed. Goal: Ravi back in class within two months, with childcare solved.
- 3. InterventionDirect: counselling Asha on talking with Ravi, and encouraging him. Environmental: the teacher agrees to catch-up support. Practical service: the little sister is enrolled in a community day-care centre.
- 4. TerminationRavi attends steadily. Sessions move from weekly to fortnightly to monthly, and follow-ups are fixed at one, three and six months.
- 5. EvaluationThe worker reviews attendance, Asha's confidence and Ravi's own feedback against the goals, then reflects on the case with a supervisor.
Practice wisdom
Common mistakes to avoid
- Rushing the study. Acting on the first story you hear leads to the wrong plan.
- Treating the diagnosis as final. New facts should change it.
- Doing things for the client instead of with them. Goals and plans are made together.
- Ending suddenly. Taper contacts and plan follow-up.
- Skipping evaluation. Without it, neither client nor worker learns anything.
Throughout every phase, respect confidentiality, informed consent and the client's right to self-determination.

Questions people ask
Frequently asked questions
What are the 5 phases of the social casework process?
They are social investigation (study), assessment (social diagnosis), intervention (treatment), termination and follow-up, and evaluation.
Who proposed the phases of social casework?
Mary Richmond (1917) described three phases: social investigation, diagnosis and treatment. Modern practice divides these into five phases.
What is the difference between assessment and social diagnosis?
They refer to the same phase. Social diagnosis is Richmond's older term, and assessment is the term used in contemporary practice. Both mean understanding the client's problem from the facts gathered.
Why should termination be gradual?
A gradual ending reduces the client's dependence on the worker step by step and avoids a feeling of abandonment. Follow-up contacts are spaced further apart, from two weeks up to a year.
Is evaluation only done at the end?
No. Evaluation is the formal judgement of whether goals were met, but progress is also checked throughout the process so the plan can be adjusted.
What techniques are used in the social study phase?
The main ones are interviews, objective observation, records and documents, secondary sources, information from family members and, where needed, special tests.
Key takeaway
Social casework is a connected sequence: study the situation, assess it carefully, intervene with the client, end the relationship gradually, and evaluate honestly. Keep the S-A-I-T-E chain in mind and every case becomes easier to organise, in the field and in the exam hall.
