Delayed Scoring
OneStream certification holders are highly valued IT professionals. Customers, partners, colleagues, and employers are confident that OneStream certification holders have the knowledge and expertise to effectively administer, architect, or provide consulting services on OneStream products. Protecting this value benefits you, as well as OneStream. As a result, OneStream will not provide an exam score immediately upon completing an exam. Candidates will have to wait 2 to 3 business days before finding out their certification status. During this period of time, OneStream will investigate exam results for statistical anomalies and evidence of exam fraud. Ensuring the accuracy of exam results certifies accurate predictions of candidate competence, as well as provides assurance that no candidate is entitled to an unfair advantage in scoring.
You invest a considerable amount of time, expense, and expertise to prepare for and complete a OneStream technical exam, which is undermined by those who engage in exam misconduct. Exam misconduct enables less qualified individuals to compete for the jobs and benefits YOU deserve. Exam misconduct erodes confidence in both OneStream programs and your skills as a certified IT professional and can lead to security and liability risks for your customers and/or employer.
To confidentially report suspected cases of misconduct, please contact the Certification team by submitting a case form on the ServiceNow Support Portal.
Score Reporting
OneStream certification exams are designed to determine if a candidate’s overall ability in a specific area either meets or exceeds what has been defined as minimal competency. Each exam item, whether multiple-choice or performance-based, contributes to that determination. Regardless of how high or low a candidate scores on an exam, only one valid conclusion can be made: the candidate either does or does not possess the minimally-acceptable knowledge, skills, and abilities for the content covered by the exam. Since the only meaningful and valid inference that can be made is a pass or fail decision, that is the only information that is reported.
Retaking an Exam
If you fail an exam on your first attempt, you must wait at least 3 days (72 hours) before a second attempt. If you do not pass an exam on your second attempt, then you must wait at least 2 weeks (14 days) between each additional attempt. Candidates will be allowed a maximum of four (4) exam attempts within a 12-month period. If you need to retake an exam that you have already passed in order to fulfill a certification track requirement, you may do so after 20 months. The exam retake fee is $300, regardless of the number of exam attempts. Beta exam test takers can only take the beta once, after which they will need to wait to retake the production exam when that certification exam becomes generally available.
