2.1 Kelman's Three Levels of Adoption
Key Takeaways
- Kelman's three levels of adoption are compliance, identification and internalisation, in increasing order of depth
- Compliance is doing what is asked because of an external reward or sanction, and it stops when the pressure stops
- Identification is adopting the change because of a valued relationship with the person or group promoting it
- Internalisation is adopting the change because it genuinely fits the individual's own values and beliefs
- The model helps change managers choose the level of intervention required and justify the change effort
Not every change needs everyone to believe in it. Some changes only need people to do the thing. Others fail completely unless people genuinely accept the reasoning. Kelman's three levels of adoption gives change managers a way to decide which situation they are in — and therefore how much effort and what kind of intervention is justified.
The three levels
| Level | What it is | What drives it | What happens when the pressure stops |
|---|---|---|---|
| Compliance | Doing what is asked | External reward or the avoidance of punishment; authority | Behaviour reverts almost immediately |
| Identification | Adopting because of a relationship | Wanting to be like, or be approved by, a respected person or group | Behaviour persists while the relationship does |
| Internalisation | Adopting because you agree | The change fits the individual's own values and beliefs | Behaviour persists independently |
Compliance
At the compliance level, a person adopts the change because of what will happen to them if they do or do not. They have not changed their mind about anything. Classic markers are an instruction, a deadline, a sanction, or a supervisor watching.
Compliance is not automatically the wrong target. If the change is a legally mandated safety procedure with immediate consequences, compliance is precisely what you need and you should not spend three months building emotional buy-in for it. Responding to an order in a crisis is a compliance-level response, and in a genuine crisis that is the appropriate one.
The danger is mistaking compliance for success. Adoption dashboards routinely light up green during the enforcement period and collapse three months later when the change team disbands. If your measures only capture behaviour while someone is checking, you are measuring compliance and calling it adoption.
Identification
At the identification level, a person adopts the change because someone they respect has adopted it, or because they want to belong to the group that has. This is why change agent networks work: the message carries more weight from a trusted peer in the same team than from a corporate email.
Identification-level adoption is more durable than compliance but it is borrowed conviction. If the respected line leader who championed the change leaves, the adoption they carried can leave with them. Practically, this means a change that depends heavily on identification needs succession thinking — spread the advocacy across several credible people rather than resting it on one charismatic manager.
Internalisation
At the internalisation level, a person has adopted the change because it genuinely fits what they believe. A nurse who adopts a new hand-hygiene protocol because they have accepted the infection evidence has internalised it. They will follow it unobserved, apply it sensibly in situations the protocol did not anticipate, and correct colleagues who do not.
Internalisation is the only level that survives the change team going away. It is also the most expensive to reach: it requires people to work through the reasoning themselves, which means dialogue, involvement and time rather than announcement.
Using the model as a change manager
The practical value of Kelman is that it lets you assess the type of change interventions required and justify the effort of the change manager. Work in this order:
- Decide the level the change actually needs. Does the benefit survive if people only comply? For a system cutover with hard enforcement, often yes. For a culture change, safety culture, or a new way of collaborating, absolutely not.
- Match the intervention to the level. Compliance needs clear instruction, visible enforcement and simple process. Identification needs credible advocates, peer networks and role modelling. Internalisation needs co-design, dialogue, insight-provoking questions and space to work things through.
- Use the gap to justify resource. This is where the model earns its place in a business case. If a sponsor wants culture change but is funding a compliance-level intervention, Kelman gives you the language to name the mismatch: "the benefit depends on internalisation, and broadcast communication only buys compliance."
Common exam traps
Candidates confuse identification and internalisation because both involve genuine adoption. The distinguishing question is where the conviction lives. In identification it lives in the relationship — "I do this because of who asked me". In internalisation it lives in the person — "I do this because I think it is right". Where a scenario mentions a respected colleague, a role model, a champion or wanting to belong, the answer is identification. Where it mentions personal values, genuine agreement, or continuing without any prompting, it is internalisation. Where it mentions instruction, authority, reward, penalty or crisis orders, it is compliance.
During a fire evacuation drill, staff follow the marshal's instructions immediately and without discussion. Which of Kelman's levels of adoption does this behaviour illustrate?
A change programme reports 95% adoption during the three-month enforcement window, then sees usage fall to 30% once the change team stands down. Which level of adoption had actually been achieved?
A team adopts a new collaboration practice mainly because a widely respected senior engineer has visibly adopted it and they want to work the way she does. Which level of adoption does this describe?
