Validates knowledge of procurement and supply management, including sourcing, negotiation, contracts, supplier relationships, supply chain integration and leadership.
CPSM tests procurement and supply management in three separate exams that you can take in any order: Core, Integration and Leadership. Each is scored on its own. Prepare one exam at a time with ISM’s 4th-edition Learning System, which follows the exam specifications.
Each exam is a separate test with its own fee and score.
Example scenario: A sole supplier proposes a 12% price increase linked to a commodity index. What would you analyse before you open the negotiation?
Example scenario: Forecast accuracy has dropped and a key supplier is short of capacity. How would you bring both into the next S&OP cycle?
Example scenario: Leadership wants to cut supplier count by a third within a year. How would you set up the program, engage stakeholders and manage the risk?

A complete question ends in a question mark; choose the one correct answer from four options (A to D).
Which type of contract places the greatest cost risk on the supplier?

A. A spend category groups related purchases so they can be planned and sourced together.
Four options are all reasonable, and you pick the one that is best or most favourable in the situation given.
Which of the following is generally MOST helpful for a buyer who wants to check whether a supplier's price increase is justified?

Buy each exam from ISM, then schedule it with Pearson VUE using a separate Pearson account. Each registration is valid for six months. After a failed attempt, wait 30 days and pay the full fee again.
Plan one exam at a time. Take the Learning System’s diagnostic practice exam first to see which tasks need the most work.
Most candidates spend 40–80 hours. Hours are per exam. Plan for the low end on the exam closest to your daily work and the high end on areas that are unfamiliar to you.
ISM’s Learning Systems are the main study materials. Buy all three exams together, or one exam at a time.
