Beta testers needed for our upcoming InterSystems IRIS SQL Specialist certification exam

Hello IRIS Community,

InterSystems Certification is developing a certification exam for InterSystems IRIS SQL specialists, and if you match the exam candidate description given below, we would like you to beta test the exam. The exam will be available for beta testing on June 9 - 12, 2024 at InterSystems Global Summit 2024, but only for Summit registrants (visit this page to learn more about Certification at GS24). Beta testing will open for all other interested beta testers on June 24, 2024. However, interested beta testers should sign up now by emailing certification@intersystems.com (please let us know if you will be beta testing at Global Summit or in our online proctored environment). The beta testing must be completed by August 2, 2024.

What are my responsibilities as a beta tester?

You will be assigned the exam and will need to take it by August 2, 2024. The exam will be administered in an online proctored environment (live-proctored during Summit), free of charge (the standard fee of $150 per exam is waived for all beta testers), and then the InterSystems Certification team will perform a careful statistical analysis of all beta test data to set a passing score for the exam. The analysis of the beta test results will take 6-8 weeks, and after the passing score is established, you will receive an email notification from InterSystems Certification informing you of the results. If your score on the exam is at or above the passing score, you will have earned the certification! 

Note: Beta test scores are completely confidential.
