Reading the MCC Blueprint: Dimensions of Care and Physician Activities

Why a grid and not a syllabus

A syllabus lists topics. A blueprint tells the test developer how to build a form that measures the right things. The MCC uses a two-way grid, and it assigns each question to one cell. The result is that two questions about the same disease can test different things. One asks you to diagnose a patient with heart failure in acute decompensation. Another asks how you discuss a new diagnosis of heart failure and prognosis with a patient. They sit in different cells, even though the topic is the same.

That is the first lesson of the blueprint: studying by organ system is necessary but not sufficient. You also need to practise the four activities within each system, and to know what changes between the four dimensions of care.

The four dimensions of care

The definitions above are our paraphrase of the MCC technical report. Note that the MCC puts a clinical topic in whichever dimension the question is really about, not the dimension you might expect from the disease. A question on a child's vaccine schedule sits under prevention. A question on a child's missed vaccines because of housing instability may sit under psychosocial aspects.

The four physician activities

• Assessment and diagnosis. History, examination, investigation and synthesis. The question asks for the most likely diagnosis, the best test or the key finding.
• Management. Planning safe, effective care with patients and other professionals. The question asks for the next best step, the treatment or the disposition.
• Communication. Interactions with patients, families and professionals, including informed consent, disclosure and breaking bad news.
• Professional behaviours. Ethics, duties, reflection and lifelong learning. The question asks what a professional physician does when duties conflict, a colleague acts unsafely, or a boundary is at risk.

What the numbers say, and what we do not know

The MCC test specifications document contains two grids with percentage targets and tolerances of plus or minus five points. The extracted text gives, for the first grid, about 25% for each of the four dimensions of care and activity weights of about 20% for assessment and diagnosis, 35% for management, 25% for communication and 20% for professional behaviours. A second grid shows different numbers. The extraction does not make clear which grid applies to Part I, so we cannot state either set as official. We think the first is more likely, but that is a judgment, not a fact.

Other sources disagree. Some commercial sites quote different splits. An older MCC page says acute and chronic care appear more often than health promotion or psychosocial care, and that assessment and management appear more often than communication and professional behaviours. That page predates the 2025 changes.

The practical conclusion is robust under either set of numbers: management questions are the biggest single block, and communication plus professional behaviours together make up a very large share. Candidates who study only diagnosis and treatment of diseases will leave marks behind.

How to revise with the grid

1. Tag your errors twice. For each wrong answer, record the domain and the cell (for example, pediatrics, prevention, management). After 200 questions you will see whether you are weak in a system or in an activity.
2. Add an activity pass to each system. When you finish a system, write one communication scenario and one professional-behaviour scenario for it. For heart failure: how you explain a new diagnosis, and what you do when a patient wants to stop treatment.
3. Build a prevention page for each life stage. Pediatric, adolescent, adult, pregnancy and older adult. Include the Canadian screening and immunization sources.
4. Practise the psychosocial lens. For common presentations, ask what social factor changes the best answer: housing, income, language, violence, addiction, cultural background, rural access.
5. Check coverage with a mixed block. If a 100-question block contains fewer than 15 questions in any cell, your bank is not reflecting the exam.

The Examination Objectives and CanMEDS roles

The MCC organizes its Examination Objectives by CanMEDS roles: Medical Expert, Communicator, Collaborator, Leader, Health Advocate, Scholar and Professional. The Medical Expert role has the most objectives, which is why the clinical content dominates. The other roles map onto the physician activities. Communicator is communication, Professional is professional behaviours, and Collaborator, Leader, Health Advocate and Scholar show up in questions on teamwork, patient safety, advocacy for populations and evidence-based decisions. Reading the objectives for these roles is a quick way to see what a professional-behaviour question looks like.

Questions that fall under Health Advocate often concern the social determinants of health, Indigenous health, access to care and the structure of the Canadian health system, which includes the Canada Health Act principles. Those principles (public administration, comprehensiveness, universality, portability and accessibility) are worth a short check against the Health Canada source.

Domain weights are editorial

Our twelve domain pages use estimated weights from 6% to 13%. They come from our reading of the MCC objectives and clinical presentations, and they are not MCC numbers. They exist to help you sequence study, and they spread questions across the grid so every domain includes prevention, acute, chronic and psychosocial items and every activity. For the list of domains and counts, see the hub. For a ranking by return on time, see the high-yield topics. For what to do with the grid in a schedule, see the study plan.

Worked examples of the grid (no exam content)

These short illustrations are our own, written to show how one topic can sit in different cells. They are not exam questions.

Using the grid to find your own gaps

After every 100 questions, make a small table with the four dimensions across and the four activities down. Put a mark in the cell for each wrong answer. A column with many marks, such as prevention, points to a content gap. A row with many marks, such as communication, points to a skill gap that no clinical reading will fix. A single cell, such as chronic care in management, points to a drug-and-target problem. This kind of analysis shows you in a week what a topic score does not show in a month.

What the grid cannot tell you

• The share of images. The MCC says items may include images, but not how many.
• The share of five-option items. The MCC states three to five options per item without a breakdown.
• The exact weight of any specialty. No discipline percentages are published.
• The share of pilot items. Some items in each section are unscored, and they are not marked.

Plan on these unknowns by covering the full range of formats in practice, and avoid relying on any website that claims to know the precise distribution.

Building a blueprint-aware weekly routine

A practical routine uses the grid without turning study into bookkeeping. Each week, choose a system from the domain list. On the first two days, learn the clinical content. On the third day, do a 40-question mixed block and log the cells of any errors. On the fourth day, write one communication scenario and one professional-behaviour scenario for the system. On the fifth day, review the prevention lens: which screening or vaccine decisions arise from this system. Use the weekend for a short timed block and for revising the error log. Over twelve weeks this gives each system four passes through the grid, and it makes the communication and professionalism marks routine rather than a last-minute sprint.
