Change management methodologies: of five models, only three lead to a credential

Which change management methodology should you choose?

Choose by the question you face: use the Standard to run a whole change effort, ADKAR to move individuals, and Kotter when a leadership coalition is the bottleneck. Lewin and Bridges serve as thinking aids. A practitioner often combines two of them.

Three of the five lead to something you can earn. The ACMP Standard feeds the CCMP®, Prosci offers its own practitioner certification, and Kotter offers a Kotter Change Certified path. Lewin and Bridges are models with no credential attached. Prices and formats below were read on the providers’ official pages on 7 October 2026. This site follows Leanova Academy, so the Standard receives the fullest treatment.

The ACMP Standard: a process for the whole effort

The Standard for Change Management© is the reference of the CCMP exam, and it is organised in five process groups. They are evaluating change impact and organisational readiness, formulating the change management strategy, developing the plan, executing it and completing the effort. It is published by the ACMP on its Standard page.

Typical artefacts and credential

The artefacts include an impact assessment, a readiness assessment, a strategy, a plan with communications and training, and a closing review. The credential is the CCMP, which asks for a degree plus 4,200 hours of experience, or secondary education plus 7,000 hours, and 21 hours of training, on the ACMP eligibility page. A QEP course such as Leanova’s CCMP Certification Exam Prep (US$595 on 7 October 2026) supplies the hours. Our explanation of the ACMP Standard details each group.

Prosci ADKAR, Kotter, Lewin and Bridges, one by one

Each of the four other approaches is narrower than the Standard, and each answers a precise question.

Prosci ADKAR®

ADKAR stands for awareness, desire, knowledge, ability and reinforcement, five outcomes that one person reaches in that order, as the Prosci ADKAR page sets out. The typical artefacts are a diagnosis of each outcome for a group of employees and a plan that targets the weakest one. Prosci is a methodology and a training company, and its certification is its own. Its Change Management Certification Program runs about three days, costs US$4,500 online or US$4,850 in person, and awards the Prosci Certified Change Practitioner badge. The page also lists ACMP QEP credits among the PDUs.

Kotter’s 8 steps

Kotter’s approach starts from urgency and a guiding coalition, and it runs through eight steps, listed on the Kotter 8 steps page. Its usual artefacts are a case for urgency, a coalition roster and a short-term wins plan. Kotter Change Certified requires six courses, and the five-day in-person programme costs US$6,000 on the official page.

Lewin’s unfreeze, change, refreeze

Lewin’s model is the oldest of the five. It sees a change as three phases: loosening current habits, moving to the new state and fixing it. It has no standard artefacts or credential; teams use it as a framing for a kick-off or a steering committee.

The Bridges transition model

Bridges separates the external change from the internal transition, and focuses on endings, a neutral zone and new beginnings. It helps when people grieve a lost role or team. It has no credential either, and a practitioner would apply it in conversations with managers rather than as a project template.

A fictional rollout: how a CCMP holder combines them

A CCMP holder uses the Standard as the backbone and borrows from the others in specific places. Consider a fictional regional bank, Banque Atlantia, replacing its branch advisory software over eighteen months.

In the impact and readiness group, the practitioner maps which of 400 advisers lose a task and which gain one. In the strategy group, she picks a Kotter-style coalition of three branch directors, since the executive team is too far from the floor. In the plan group she uses ADKAR to design the training: advisers who lack knowledge get workshops, those who lack desire get a conversation with their manager. Bridges guides the talks with the back-office team whose role disappears, and Lewin supplies the three-phase language for the steering committee. The Standard’s last group ties it together with a review and a handover.

No single credential was needed for that mix. The CCMP shows that the holder knows the whole process, and the models are used as tools. A broader view of the field is in our guide to organizational change management, and unfamiliar terms are defined in the change management glossary.

Other frameworks you may meet: APMG and the Change Management Institute

APMG International and the Change Management Institute offer two further paths, each with a published structure. APMG’s Change Management exam comes in a Foundation (50 questions, 40 minutes, pass mark 25 out of 50) and a Practitioner (80 scenario questions, 2 hours 30, pass mark 40 out of 80), based on a syllabus developed with the Change Management Institute, according to the APMG product page.

The Change Management Institute runs Accredited Change Professional, a members-only portfolio assessment against its Competency Model. Its page lists Foundation at USD 525 and Specialist at USD 675. They are separate from the ACMP: a holder of one is not thereby a CCMP.

Which one to pursue depends on where your clients and employers sit. If your target is a learning route that also earns the 21 hours, the self-paced LCeX-Professional course (21 QEP hours, US$595, no prerequisite) is one option; the ACMP exam still follows separately.
