CSPH Cheat Sheet 2026: One-Page Review of Must-Know Facts

What This Cheat Sheet Covers (and What It Doesn't)

This page is a one-screen refresher for the Certified Specialist of Public Housing credential offered by the National Association of Housing and Redevelopment Officials (NAHRO). Other credentials share the same four-letter acronym, and their exam details have nothing to do with this one. If you landed here from a search for a different "CSPH," the fees, domains, and logistics below will not apply to you. For a plain-language orientation, see What Is CSPH Certification? or What Does CSPH Stand For?.

The credential is aimed at people who work in public housing agencies: occupancy staff, eligibility and recertification specialists, waitlist administrators, and the supervisors who review their work. It combined two earlier NAHRO credentials, the CSO-PH and the CSEC-PH, into a single designation starting September 1, 2025. If you hold a predecessor credential or have old study notes labeled with those names, read them as background rather than as a description of the current exam.

The Fast Facts: Issuer, Format, Fees

• Issuer: NAHRO.
• Required exam: Public Housing Essentials, previously titled Public Housing Occupancy, Eligibility, Income, and Rent Calculation (PHOEIR). No separately dated exam version appears on the current listing.
• Standalone exam fee: USD 160 for NAHRO members, USD 260 for nonmembers.
• Delivery: On demand through the NAHRO Learning Portal. Access expires 14 days after purchase, so buy the exam when you are ready to sit it, not months ahead.
• Certification term: Expires at the end of the month three years after approval.
• Not verified in current issuer sources: question count, attempt timer, attempt allowance, numeric passing score, and pass rate.

That last bullet matters. Older PHOEIR instructions reportedly described ClassMarker delivery, two attempts within two weeks, and a continuous two-hour timer per attempt. The page that published those details now returns a 404 error and was not freshly retrieved, so those details describe a legacy exam, not the current Essentials exam. Confirm logistics on the NAHRO Learning Portal at the moment you purchase. For deeper discussion of what is and isn't known, see CSPH Passing Score 2026 and CSPH Pass Rate 2026: What the Data Shows.

The Six Competency Topics at a Glance

The six lines below come from the competency statements in NAHRO's current credential application. They are best treated as unweighted preparation topics. No formal weighted exam blueprint was verified, so these headings do not establish exhaustive exam coverage or an official count of exam domains. The Essentials course publishes additional learning objectives, but those describe preparation curriculum rather than an exam blueprint. A fuller walk-through lives in CSPH Exam Domains 2026: Complete Guide to All 6 Content Areas.

Income, Rent, and Utility Allowance Reminders

Domains 1 and 2 carry the most calculation-heavy work, and they are where candidates most often need hands-on practice rather than rereading. The cheat-sheet version is a sequence rather than a formula:

1. Establish who is in the household and which members' income counts.
2. Identify each income and asset source and classify it as included or excluded.
3. Annualize carefully, using the verification you have in hand.
4. Apply adjustments as the governing rules allow.
5. Calculate rent from the resulting figures.
6. Apply the utility allowance and confirm the final tenant payment.

Because rules and thresholds change, any worked example you practice should carry a stated date and a stated set of assumptions. If a practice question gives no basis for its figures, treat it with suspicion. The CSPH practice test site is a place to drill this kind of scenario work in a timed format.

Occupancy Cycle, Interviewing, and Waitlists

Domains 3, 4, and 5 are process knowledge. Expect scenario-style thinking: a situation occurs, and you must identify the correct next step, the correct documentation, or the error in what was done. Exact question style for the current exam was not verified, so prepare for application of concepts rather than memorized definitions.

Occupancy cycle checkpoints

• Be able to narrate the cycle from first contact through move-out and name the staff action at each stage.
• Know which events trigger a new income determination and which only require a record update.
• Understand how a mistake early in the cycle (a missed household member, an unverified source) propagates into rent errors later.

Interviewing and screening checkpoints

• Practice identifying what information a given interview must collect and what must be verified independently.
• Think in terms of consistency: the same questions and standards applied to every applicant.
• Be ready to decide what to do when an applicant's statements and documents do not match.

Waitlist checkpoints

• Know how a list is opened, updated, ordered, and purged, and why each step needs a paper trail.
• Be able to spot a waitlist practice that could look arbitrary or inconsistent.

Lease and Grievance Procedures

Domain 6 rewards candidates who know procedure cold. Treat lease and grievance questions as sequencing and notice problems: who must be told what, in what form, and what rights the resident has at each step. Study the lease as a document, section by section, and then walk through a grievance from the initial dispute to resolution. Where your agency's own policies differ from general practice, remember that the exam tests the credential's competency standards, not your local habits.

Eligibility Path and Waivers

To earn the certification you need all of the following. Full detail is in CSPH Requirements 2026: Eligibility, Prerequisites & How to Qualify.

1. Education and experience: a high school diploma or equivalent plus six months of experience, or an associate degree or higher, which removes the six-month experience requirement.
2. Public Housing Essentials training or an approved waiver.
3. NAHRO ethics training.
4. Passing the required exam.
5. Submission of a certification application.

The specialist-training waiver may be supported by five years of public housing experience plus demonstrated knowledge, or by accepted equivalent non-NAHRO training. Two things cannot be waived: the ethics requirement and the exam. NAHRO's certification FAQs also describe a CSPH Fast Track, so check the current policy page if you hold a predecessor credential or have long experience.

Renewal, Grace Period, and Ethics Requirements

• Term: certification expires at the end of the month three years after approval.
• CEUs: 0.5 CEUs earned after the current certificate's issue date and within the past three years.
• Ethics: required ethics training. NAHRO's policy effective January 1, 2026 specifically requires Ethics for Housers for renewal, even though the application still lists alternative legacy ethics course names. Follow the policy, not the older list.
• Transcript: every requirement must appear on your NAHRO transcript before you apply.
• Late renewal: a six-month grace period applies. After that, you must repeat the full certification process, including the exam.

Cost and Credit Comparison Table

The figures below come from NAHRO listings. Prices and dates change, so verify at purchase. For a full breakdown, see CSPH Certification Cost 2026: Complete Pricing Breakdown.

Note the credit discrepancy: the October listings award 2.6 CEUs, while the general catalog lists 24 instructional hours and 2.4 CEUs for the course. Course hours and CEUs describe training, not exam time, so do not read them as the length of the test. For cost-versus-benefit thinking, read Is the CSPH Certification Worth It? and the CSPH Salary Guide 2026; neither can rest on a verified pay premium for this specific credential.

What Is Still Unverified

An honest cheat sheet lists its blanks. As of the October 5, 2026 review, the retrieved current issuer sources did not confirm:

• The number of questions on the current exam.
• The attempt timer and the number of attempts allowed.
• A numeric passing score.
• Any pass rate.
• A formal weighted blueprint or official count of exam domains.

Any site that quotes a precise pass rate, question count, or domain weighting for the current CSPH without citing a NAHRO source should be treated cautiously. Difficulty is similarly hard to quantify; the discussion in How Hard Is the CSPH Exam? is built around the nature of the content rather than invented statistics.

A Domain Order That Fits the Material

This is the only study-planning section in this cheat sheet, and it is tied to how the six topics depend on each other. Eligibility and income feed rent calculation, so they come first; process and procedure topics come after. A longer plan lives in the CSPH Study Guide 2026.

Because the exam is on demand with 14-day access after purchase, finish this plan before you buy the exam, not after. Sitting dates and windows are covered in CSPH Exam Dates 2026.
