ISM defines the CPSD as the Supply Management Core exam plus the Essentials in Supplier Diversity exam. Hold a current CPSM and the Core is already done - only the Essentials sitting remains, and passing it even returns 20 continuing education hours.
Core carries 165 questions in 3 hours per ISM's current 4th-edition product page; Essentials in Supplier Diversity carries 150 questions in 2 hours 30 minutes per its live product page.
Core passes at 400 on the 100-600 scale like every CPSM exam - but ISM sets the Essentials in Supplier Diversity bar higher at 480, reported in increments of 10. Two different bars, one designation; plan for the harder one.
ISM's official September 2026 pricing schedule lists each exam at 495 US dollars for members and 795 for nonmembers, with the certification application free for members and 295 dollars for nonmembers.
What the Two CPSD Exams Actually Cover
Supply Management Core is the shared foundation - the identical sitting that anchors the CPSM and APSM pathways, covering Sourcing, Category Management, Negotiation, Legal Aspects of Supply Chain Management, Supplier Relationship Management, Cost and Price Management, and Financial Analysis: 165 questions in 3 hours on the current 4th-edition product page. Because it is shared, a current CPSM holder - or an APSM holder inside the five-year validity - has already cleared it, and one vendor timing note applies right now: the 4th-edition Core is purchasable today, but ISM says Pearson scheduling for it begins in early November 2026.
Essentials in Supplier Diversity is the specialization sitting, and its product page publishes six assessed competency areas: Policies and Strategic Planning; Sourcing and Supplier Development; Finance and Budgeting; Metrics, Measurement, and Program Oversight; Training and Development; and Advocacy, Marketing, and Outreach. The exam runs 150 questions in 2 hours 30 minutes, English only, and it passes at 480 on the 100-600 scale - 80 points above every other ISM exam bar, the detail most candidates miss until the score report.
Eligibility is more flexible than the CPSM's: five years of professional, nonclerical supplier diversity or supply chain experience - which per the Certification Handbook does not need to be your primary job function - or three years of it with a regionally accredited bachelor's degree. Scores stay valid four years, so the exams can be passed while the experience is still accumulating; the application, free for members and 295 dollars for nonmembers, follows the passes.
Can You Take the CPSD Exams From Home?
Yes, in select regions. ISM's exam overview states it offers an online proctored exam option you can take from the comfort of your own home or office alongside worldwide testing facilities, and Pearson's ISM program page confirms the route from the delivery side: take your ISM exam conveniently from home through OnVUE online proctoring, with certain regional restrictions. After purchasing from ISM, your confirmation email leads to Pearson scheduling, where the home or office option appears wherever online delivery is offered.
The published exclusion list applies to the whole ISM family: online exams are currently not available in the People's Republic of China, Japan, Slovenia, Cuba, Iran, North Korea, Sudan, or Syria. Remote sittings are live proctored with enhanced security and AI technology, the proctors speak English only, and candidates who cannot communicate verbally in English with the proctor are directed to a test center instead.
The at-home setup rules come from Pearson's dedicated ISM OnVUE page: Windows 10 or macOS 14 or higher, webcam, microphone, and speaker with no headphones or headsets, one display only, at least 6 Mbps down and 2 Mbps up, every application except OnVUE closed, and no virtual machines, VPNs, or corporate networks. Run the system test on the same device and network before exam day, create a fresh Pearson account because your ISM login does not carry over, and make sure the name on your photo ID exactly matches your ISM registration - any of those failing at check-in can forfeit a fee ISM already treats as non-refundable.
What the CPSD Sittings Cost
The fee structure is flat: each of the two exams costs 495 US dollars for ISM members and 795 for nonmembers on the September 2026 pricing schedule, so a first-time candidate pays 990 or 1,590 dollars in exam fees, plus the certification application at 0 dollars member or 295 nonmember after the second pass. A current CPSM holder pays for one sitting only - and ISM credits 20 continuing education hours when the Essentials pass posts.
The penalty economics mirror the CPSM's: every registration is non-refundable and expires six months after ISM processes it, a 30-day extension costs 115 dollars member or 195 nonmember if requested before expiry, and a failed exam means a 30-day wait plus a new full-price registration with no retake discount. ISM's own FAQ quotes average total ranges of 495 to 1,337 dollars for members and 795 to 2,028 for nonmembers - those bundle study materials, which is why the tops sit well above the exam-fee math.
After the designation, the meter keeps running gently: the CPSD renews every three years with 60 continuing education hours and a 135-dollar member or 295-dollar nonmember recertification fee. And one budgeting line stays honest: the fees above go to ISM. The service fee for having the sittings handled end to end is separate, quoted against your exams and delivery route - and it is due only after the agreed result posts.

How the Service Works
You send the brief
You get a straight feasibility answer
The sitting is handled end to end
The pass posts, then the fee
What You Get
A team that has read the actual documents: ISM's live product pages for the Essentials exam's six competency areas, 150-question format, and 2.5-hour clock, the shared Core exam's current specification, the September 2026 pricing PDF, the Certification Handbook's 480 bar and eligibility rules, and Pearson's ISM program and dedicated OnVUE pages for the at-home requirements. Every fact on this page traces to one of those.
A sitting aligned to the published program rules - the right exams for what you already hold, a compliant delivery route inside your region, the registration clocks tracked before they lapse, and the ID and minimums handled before exam day - and a payment structure that keeps the risk where it belongs: the service fee is due only after the agreed result posts.
Handling It Safely
Every engagement starts from what ISM and Pearson VUE publish today: the two-exam structure, the shared Core rule, the 480 Essentials bar, the fee schedule in the pricing PDF, the six-month registration validity, the online-exclusion country list, and the OnVUE minimums on Pearson's dedicated page. The plan is built inside those boundaries, not around them.
What we control is the quality, discretion, and privacy of the engagement: an honest feasibility answer before anything starts, a structured sitting plan for your exact exams and dates, and a fee that follows the result. Your details stay private, we never ask for more than the sitting requires, and the delivery-route rules are checked before booking - never discovered after it.
Payment: After the Result
The exam fees - 495 to 795 US dollars per sitting by membership status - go to ISM through the normal purchase route, and the application fee follows the second pass. The service fee for the sitting is due only after the agreed result posts: you verify the scaled score report, and then settle.
No upfront service charge, no fee to hear the feasibility answer, and no invoice if the agreed result does not post. That structure is the whole point: the sitting team carries the execution risk, not you.
Sittings Handled
I already held the CPSM and nearly bought both exams. They caught that only the Essentials applied, handled the sitting from home, and the 20 continuing education hours posted with the pass. Fee waited for the result.
The 480 bar was the surprise - every practice target I had was built to 400. They replanned the Essentials preparation properly, handled the sitting end to end, and I paid after the scaled report posted.
Core scheduling was not even open for my dates, so they sequenced Essentials first and Core the week scheduling opened. Both handled, no lapsed registrations, settled after the second pass.
