AICP Exam Content Outline Explained: All 9 Domains and What They Cover

If you've searched for what's on the AICP exam, you've probably found two different answers. Some study materials describe five topic areas with weights like 25% and 30%. Others describe nine. Only one of those is current, and if you're studying from the wrong one, you're allocating your time based on an exam that no longer exists.

This guide lays out the current AICP exam content outline, what each of the nine domains actually tests, how the new outline maps to the old one, and how to use the weightings to plan your studying. Think of it as home base: each domain below links to a deeper guide.

The Basics: How the AICP Exam Is Structured

According to APA's official content outline, the AICP Certification Exam has 170 multiple-choice questions. Twenty of those are unidentified questions still in development, which means 150 questions count toward your score. You won't know which 20 are unscored, so treat every question as if it counts.

The exam also includes scenario questions, where three to five questions are tied to a single scenario. These reward the ability to read carefully and apply knowledge, not just recall it.

APA also notes that the exam tests planning as practiced across the United States, not in any particular state or region. If your day job revolves around your own state's statutes, remember that the exam is looking for the national answer.

The Current AICP Exam Outline at a Glance

The current outline covers nine major topic areas. APA publishes the percentage of questions drawn from each one. We've added an approximate number of scored questions per domain, based on 150 scored questions, to make the weights easier to picture.

The question counts are estimates for planning purposes only. APA notes that the exam includes questions from all nine topics but may not include questions from every sub-area within them.

What Each Domain Covers

Fundamental Planning Knowledge (15%). This is the domain most people picture when they think of the AICP exam: planning history, planning theory, patterns of human settlement, and the legal foundations of planning, including property rights, police power, and eminent domain. It also covers core values of planning like equity and the public interest, the terminology of related professions, and how technology is changing planning practice. Because it's so broad, it's also where candidates most often over-study. Our Fundamental Planning Knowledge guide shows how to prioritize, and our Case Law, Acts & Legislation guide covers the legal side in depth.

Plan and Policy Development (15%). This domain is about how plans get made: scoping, visioning, setting goals and objectives, drafting policy, evaluating consequences, and involving stakeholders. It also includes funding considerations, community character and form, and mediation among competing interests. Expect a lot of "what should the planner do next" questions, covered in our Plan and Policy Development guide.

Communication and Interaction (13%). Often dismissed as soft skills, this is one of the heaviest domains on the exam. It covers clear communication, running meetings, consensus building, outreach to underserved communities, accessibility, evidence-based argument, and managing politically sensitive situations. See our full guide to the Communication and Interaction domain.

Plan Implementation (12%). Once a plan is adopted, how does it actually happen? This domain covers codes and regulations, capital improvement programs, funding and financing, consistency review, strategic partnerships, and monitoring plans over time. Our Plan Implementation guide walks through the tools.

Areas of Practice (12%). The widest domain on the exam, spanning comprehensive and current planning, transportation, housing, economic development, urban design, sustainability, hazard mitigation, natural resources, historic preservation, parks, food systems, health, rural planning, equity planning, and regional planning. The challenge is breadth, which our Areas of Practice guide tackles directly.

Research and Assessment Methods (11%). How planners gather and interpret information: qualitative and quantitative research, data quality and validity, spatial analysis and GIS, community engagement as research, and data collection that respects privacy. It's one of the domains candidates feel least ready for, as we cover in our Research and Assessment Methods guide.

AICP Code of Ethics and Professional Conduct (10%). Every ethics question is based on the current Code of Ethics. This domain covers the planner's responsibilities to the public, to clients and employers, and to the profession, along with the enforceable Rules of Conduct. Learn the reasoning method in AICP Ethics Questions: How to Choose the Best Answer.

Administration and Management (6%). The business side of planning work: project and program management, RFPs and RFQs, contracts, budgets, staffing, external relationships with boards and commissions, and results-oriented accountability.

Leadership (6%). Advocacy, accountability to the public interest, ethical aspects of leadership, mentoring, problem-solving, and promoting the value of planning. Both of these smaller domains are covered together in our guide to Leadership, Administration and Management.

Old Outline vs. New Outline: Why So Many Study Guides Get It Wrong

APA updated the content outline in December 2021, and the new structure took effect with the 2022 exams. Before that, the exam used five domains:

The current outline also added Communication and Interaction (13%), which wasn't a stand-alone domain before.

Most of the underlying material didn't disappear. It was reorganized into more specific categories. But the weights shifted in ways that matter. Leadership, administration, and management went from 5% combined to 12%. Communication became its own 13% domain. And the old heavyweight domains got smaller.

Many free chapter prep decks, older PDFs, and secondhand study guides still circulate the five-domain outline with its 25/30/30/5/10 weights. If a resource you're using shows those numbers, it was built for the old exam. The content may still be useful, but don't let it decide how you spend your study time.

How to Use the Outline to Plan Your Studying

Weight your time, then adjust for your background. Start by splitting your study time roughly in proportion to each domain's weight. Then shift time away from domains you work in every day and toward the ones you don't.

Don't skip the small domains. Leadership and Administration and Management are 6% each, but together they're 12% of the exam, the same as Areas of Practice.

Remember that the "soft" domains add up. Communication and Interaction, Leadership, and Administration and Management together make up a quarter of the exam.

Study for the national answer. When in doubt, choose the answer that reflects general best practice nationwide.

Use the outline as a checklist. Print the full outline from APA's website and check off each sub-area as you cover it.

Our week-by-week AICP study plan is built around these nine domains, so you can see where each one fits in a 12-week schedule. When you're ready to test yourself, try our AICP practice questions with explanations.

Study Materials Built Around the Current Outline

If you want one resource that covers all nine domains without piecing together outdated PDFs, the Comprehensive Planning Study Guide is organized around the current outline. The Study Guide Bundle pairs it with our case law, timeline, and people and books guides. Everything is a one-time purchase with lifetime access.
