How are the Exams scored? What is passing?

ISM maintains multiple versions, or forms, of the exam. While the content of the exam remains constant, the actual questions used in the exam will change. Different forms of the exam use different questions, the level of difficulty will vary slightly from test to test. To compensate for these variations, a statistical procedure known as equating is used to account for differences in test difficulty. The passing score is not calculated based upon percentages.

For example, let's suppose we have two test forms of an exam — Test A and Test B. Now suppose it is established that in order to pass Test A, a person must answer 32 out of 60 questions correct. Furthermore, suppose that Test B is somewhat easier than Test A. To compensate for this difference, the passing score for Test B is adjusted to prevent any "bonus" being given to the candidates taking Test B. Thus, it may be established that a candidate must get a score of 34 out of 60 on Test B in order to pass. This is test equating. It holds candidates to the same standard in terms of difficulty, regardless of which version is taken.

Due to this method of equating the percentage of correct answers varies from exam to exam. Then, to maintain consistency in scoring, a second statistical procedure called scaling is used. Scaling converts all scores to a scale ranging from 100 to 600 with a passing score set at 400. Thus, the scores you receive from ISM are actually scaled scores. If the scaled score on the Supply Management Core Exam ranges from 100 to 390, this means you failed that Exam. If the scaled score is in the range of 400 to 600, you passed that Exam. Scaling on the CPSD Essentials in Supplier Diversity exam follows this same methodology.

What do I do if I fail an exam?

If you fail an exam, you should use the score report that you receive from the test center to re-focus your study effort on any task area(s) where you did not answer approximately 75% of the questions correctly. Then revisit the study material you used to prepare for the exams and purchase additional sources if more in-depth studying is needed.


To re-test, you will again need to register with ISM and pay the appropriate member or non-member fee.


ISM has a 30-day retake policy for the CPSM® Exams. If you are unsuccessful on an exam you must wait 30 days before you are eligible to re-take that specific exam.

Do I have to pay to re-take the exam?

Yes, you will again need to register with ISM and pay the appropriate member or non-member fee. There is no discount on re-tests.


ISM has a 30-day retake policy for the CPSM® Exams. If you are unsuccessful on an exam you must wait 30 days before you are eligible to re-take that specific exam.

Am I able to see the questions that I got wrong on an exam?

Specific exam questions and answers are not made public. A score report for each exam is provided upon completion. The score report provides detail about the task areas where questions were missed. Task areas that you answered less than 75% of the questions correct is an area that requires more study.

How long are my CPSD™ Exam scores valid?

CPSD™ Exam scores are valid for 4 years from the date they are taken. If an exam score is more than 4 years old, the exam must be taken and passed again before applying for the CPSD™.


How do I register for CPSD™ Exam(s)? How do I know where the closest test center is located?

Your exam registration is valid for six months from the day ISM processes your registration. Payment is required in advance. You must test by the expiration date to avoid forfeiting your exam fees.

I am having issues getting my work experience documentation, do you have any suggestions?

Remember to use employer letterhead, have a current or previous supervisor or human resource department sign each letter, and include each title, and the length of time the title was held (from mo/yr to mo/yr).

Titles referenced in the samples are representative only and do not cover the range of titles held or used in the field.

Questions? Call ISM Member Services at 1.480.752.6276, opt. 8


Some of the more common situations encountered when documenting experience, and recommended solutions, are covered below:



Contact a previous supervisor, or other individual you worked with, who can certify your employment history and have them write a letter for you. Have them explain the situation briefly and identify their previous relationship to you within the company.



Consider researching information at your public library or local government entity for documents of incorporation. You may be able to find the entity holding the personnel/employment records. You may also want to ask your present employer if they verified your previous experience, job titles, dates held, and so on. If this was done, your current employer can certify previous experience.



If you have a title that is not normally associated with professional purchasing, supply management, or supply chain management, and you are not sure if you qualify, you may get your experience approved upfront for a nominal $25 fee. Experience must be documented on an official job description or letter on company letterhead. ISM does not allow self-verification. Letters should come from your current or previous human resources department or supervisor, explain your responsibilities in detail and list job duties. Please make sure they specify the percentage of time spent in each area/job function. ISM will review the material and notify you of the decision.



Ask your commanding officer for a letter documenting your experience. In most cases we have received the DD 214. In some cases military review or discharge documents may also help document your experience.


Once earned, how do I maintain my CPSD™?

CPSD’s are required to recertify every 3 years with 60 Continuing Education Hours (CEHs). CPSD’s are encouraged to recertify within the 60 days prior to the expiration date. Once your certification has expired, you will be given a one-year grace period in which you can recertify with no penalty. Candidates in their grace period will not be recognized as a CPSD™ nor will they be allowed to use the designation. Certificate dates will appear on the certificate as if the recertification had been completed prior to the expiration of your previous certificate.


Please notify the Certification Department when you move or change jobs to keep your records current, as we may attempt to notify individuals when their designation has expired. You can also update your contact information by logging into and going to My Account to update your contact information.

What are the requirements for online exams?

In order to ensure the proper environment for proctored exams, you must have a quiet, private location, a reliable computer with a webcam, access to one of the approved internet browsers, and a strong internet connection. It is your responsibility to verify your computer meets the technical requirements to take the online proctored exam.
