- CSPH is issued by NAHRO and merged the former CSO-PH and CSEC-PH credentials effective September 1, 2025.
- The six domains come from NAHRO's credential application competency statements, not a published weighted exam blueprint.
- The required exam is Public Housing Essentials, formerly PHOEIR; standalone cost is USD 160 member or USD 260 nonmember.
- The retired July Essentials course excluded HOTMA income and asset training, so verify HOTMA coverage before assuming it.
What the Six Content Areas Actually Are
If you are searching for the "CSPH exam domains," start with an important clarification: the six areas below are the competency statements listed on NAHRO's current credential application for the Certified Specialist of Public Housing. They are useful, official-sourced preparation topics. They are not a weighted exam blueprint, and NAHRO has not published percentages telling you how many questions come from each area. Treat the list as a map of the territory, not a scoring formula.
That distinction matters because many candidates arrive from third-party sites that present invented domain weights. Nothing in the current NAHRO listings supports those numbers, so this guide does not use them. For the bigger picture of what the credential is, see our overview, What Is CSPH Certification?, and for eligibility details see CSPH Requirements 2026: Eligibility, Prerequisites & How to Qualify.
| Domain | Competency Statement | Core Skill Type |
|---|---|---|
| 1 | Evaluating eligibility and income | Rules application and verification |
| 2 | Calculating rents and utility allowances accurately | Quantitative, step-by-step math |
| 3 | Understanding the tasks and processes associated with the public housing occupancy cycle | Process sequencing |
| 4 | Effective interviewing and screening | Judgment and communication |
| 5 | Maintaining waitlists | Administrative procedure |
| 6 | Understanding lease and grievance procedures | Rights, notices, and due process |
Domain 1: Evaluating Eligibility and Income
Evaluating eligibility and income
This is the front door of every public housing case. You must be able to determine whether a household qualifies and what counts as its income.
- Applicant eligibility factors: household composition, family definitions, and who is a household member
- Citizenship and immigration status concepts as they affect eligibility and assistance
- Identifying income sources, including wages, benefits, and other recurring amounts
- Understanding assets and how they relate to income determinations
- Third-party verification principles and documentation standards
Candidates often underestimate how much of the later domains depends on getting Domain 1 right. A mis-categorized income source here propagates directly into the rent calculation in Domain 2. When you study, practice working a case from raw household information to a defensible annual income figure, and be ready to explain why each included or excluded item is treated the way it is.
Where candidates slip
- Treating verification as paperwork. The exam logic around verification is about reliability of information, not just collecting documents.
- Blurring income and assets. They interact, but they are distinct concepts with distinct rules.
- Ignoring household changes. Who is in the household drives deductions, allowances, and eligibility.
Domain 2: Calculating Rents and Utility Allowances
Calculating rents and utility allowances accurately
This is the most quantitative area. Accuracy is the keyword in the competency statement itself.
- Moving from annual income through adjustments to a rent determination
- Understanding which deductions apply and how household circumstances trigger them
- Applying a utility allowance correctly when the tenant pays some or all utilities
- Recognizing when a calculation changes because circumstances change
- Checking your work for internal consistency
Because this domain rewards precision, it benefits most from repetition on worked scenarios. Build a habit of writing out each step rather than computing in your head. A common failure pattern is getting the logic right but applying a rule at the wrong step in the sequence. Our How Hard Is the CSPH Exam? Complete Difficulty Guide 2026 discusses which areas tend to feel hardest, and rent calculation is a frequent candidate worry.
Key Takeaway
Practice calculations with dated assumptions written at the top of each worked problem. Rules and thresholds change over time, so labeling the assumptions you used keeps you from memorizing numbers that may no longer apply.
Domain 3: The Public Housing Occupancy Cycle
Understanding the tasks and processes associated with the public housing occupancy cycle
This domain is about sequence and timing: what happens, in what order, from application through occupancy and beyond.
- Application intake through to housing offer and move-in
- Initial occupancy tasks versus ongoing tasks during tenancy
- Periodic reexaminations and interim changes during the tenancy
- Tenancy-ending processes, including transfers and move-outs
- How documentation and recordkeeping thread through each stage
Think of the occupancy cycle as a timeline. Exam-style questions in process domains typically test whether you know what comes next, what triggers a change, or what task belongs to which stage. A strong study technique is to draw the lifecycle on one page and attach each task to a stage, then quiz yourself by covering the stage labels.
Domain 4: Interviewing and Screening
Effective interviewing and screening
This domain moves from numbers to people. It covers how you gather information and how you evaluate applicants fairly and consistently.
- Conducting interviews that elicit complete and accurate information
- Communicating clearly with applicants and residents, including those with barriers
- Applying screening criteria consistently and without discrimination
- Understanding fair housing obligations in how you ask and decide
- Documenting the basis for decisions
Scenario questions are common in judgment-heavy domains. When you practice, focus on the reasoning: what is the compliant, consistent, well-documented action, and why are the tempting alternatives wrong? The best answer is usually the one that treats similar applicants alike and leaves a clear record.
Domain 5: Maintaining Waitlists
Maintaining waitlists
Waitlist management is procedural but unforgiving: errors affect real applicants' positions and can create fairness and compliance problems.
- Opening, closing, and updating a waiting list
- Applying preferences and ordering rules consistently
- Purging or updating the list when applicants do not respond or circumstances change
- Communicating status and decisions to applicants
- Keeping records that justify placement and removal decisions
This domain is a good candidate for flashcards because it is rule-and-procedure heavy. Pair each procedure with the reason it exists, typically fairness, transparency, and defensibility, and the right answers become easier to reason out rather than just recall.
Domain 6: Lease and Grievance Procedures
Understanding lease and grievance procedures
The final domain covers the contractual and due-process framework of tenancy.
- Lease provisions and the obligations they place on housing authority and resident
- Notice requirements and the timing of lease actions
- The grievance process, including how a resident challenges an authority action
- Informal and formal steps and what each is designed to accomplish
- Documentation that supports lease enforcement decisions
Questions here often turn on who must do what, by when, and in what form. When studying, build a small table for each procedure listing the trigger, the required notice, the resident's options, and the authority's next step.
Sequencing Your Preparation Around the Domains
Rather than studying in the order the list is printed, consider ordering by dependency. Domains 1 and 2 are tightly linked and form the quantitative core; Domain 3 gives you the frame that holds the rest together. The people-and-procedure domains then layer on top. For a broader plan, see CSPH Study Guide 2026: How to Pass on Your First Attempt. A domain-sequenced outline might look like this:
Eligibility and Income (Domain 1)
- Build income and household-composition fluency
- Work verification scenarios end to end
Rents and Utility Allowances (Domain 2)
- Rework Domain 1 cases through to a rent figure
- Write out every step with dated assumptions
Occupancy Cycle and Screening (Domains 3 and 4)
- Draw the lifecycle timeline and attach tasks to stages
- Practice interview and screening scenarios
Waitlists, Leases, and Grievances (Domains 5 and 6)
- Build procedure tables for notices and timelines
- Run a mixed review across all six domains
Calculation-heavy material goes first because it needs the most repetition, and the procedural domains go last because they respond well to compact review. If you want a condensed reference as you near your test date, our CSPH Cheat Sheet 2026: One-Page Review of Must-Know Facts is a useful companion. You can also test yourself against scenario-style questions on the CSPH practice test site.
Exam Logistics and Costs You Can Verify
Because some details of the current exam were not verifiable from NAHRO's current public sources, it helps to separate what is confirmed from what is not.
| Item | What Is Confirmed |
|---|---|
| Required exam | Public Housing Essentials (previously PHOEIR) |
| Standalone exam fee | USD 160 member / USD 260 nonmember |
| Delivery | On demand through the NAHRO Learning Portal |
| Access window | Expires 14 days after purchase |
| Question count, timer, attempt allowance, passing score, pass rate | Not verified in current issuer sources |
The exam is only one piece of certification. Candidates also need the required training or an approved waiver, NAHRO ethics training, and a certification application. Training is not interchangeable with exam time: the October 20-29, 2026 preparation course lists 2.6 CEUs, while the general catalog lists 24 instructional hours and 2.4 CEUs. For full pricing, including the course and the training-and-exam bundle, read CSPH Certification Cost 2026: Complete Pricing Breakdown. For timing, see CSPH Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
The HOTMA Question: Check Before You Assume
Income and asset rules are central to Domains 1 and 2, and HOTMA (the Housing Opportunity Through Modernization Act) is a major source of change in how those calculations work. Here is what the record actually shows: the still-public July Essentials course is now marked retired and explicitly excludes HOTMA income and asset calculation training.
That is a statement about that specific retired course. It does not prove what the current exam does or does not cover, and it is not a reason to import another issuer's HOTMA syllabus into your NAHRO preparation. The practical response is straightforward:
- Read the learning objectives on the current course listing for the session you plan to attend.
- Confirm with NAHRO which rule set the current exam version assumes if your study materials differ.
- Label every practice calculation with the rules and date it assumes, so you can quickly spot a mismatch.
Key Takeaway
The six domains tell you what to study; they do not tell you which version of the income and asset rules the exam assumes. Resolve that with the current issuer listings rather than with third-party guesses.
Frequently Asked Questions
No. They reproduce the competency statements from NAHRO's current credential application as unweighted preparation topics. No formal weighted exam blueprint was verified, so do not rely on any site that assigns percentages to them.
It is the same required exam under a new name: Public Housing Essentials was previously known as PHOEIR. However, legacy PHOEIR logistics, such as timer and attempt rules, should not be assumed to carry over to the current exam.
The standalone exam fee is USD 160 for NAHRO members and USD 260 for nonmembers. The preparation course and training-and-exam bundle cost more; see our pricing breakdown for the full picture.
Certification expires at the end of the month three years after approval. Renewal requires 0.5 CEUs earned within that window, required ethics training (NAHRO's policy effective January 1, 2026 specifically requires Ethics for Housers), and an application. A six-month late-renewal grace period applies; after that, the full process, including the exam, must be repeated.
