Beta Testers Needed for our Upcoming InterSystems IRIS Developer Professional Certification Exam

#Certification #ObjectScript #SQL #InterSystems IRIS #InterSystems IRIS for Health

Hello IRIS community,  

InterSystems Certification is developing a certification exam for InterSystems IRIS Developer professionals, 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 March 3, 2025. Interested beta testers should sign up now by emailing certification@intersystems.com. 

The beta testing must be completed by April 18, 2025. 

What are my responsibilities as a beta tester? 

You will be assigned the exam and will need to take it by April 18, 2025. The exam will be administered in an online proctored environment free of charge (the standard fee of $150 per exam is waived for all beta testers). The InterSystems Certification team will then 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 once 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. 

 

Exam Details 

Exam title: InterSystems IRIS Developer Professional 

Candidate description: A back-end software developer who: 

  • writes and executes efficient, scalable, maintainable, and secure code on (or adjacent to) InterSystems IRIS using best practices for the development life cycle, 
  • effectively communicates development needs to systems and operations teams (e.g., database architecture strategy),  
  • integrates InterSystems IRIS with modern development practices and patterns, and  
  • is familiar with the different data models and modes of access for InterSystems IRIS (ObjectScript, Python, SQL, JDBC/ODBC, REST, language gateways, etc.) 

Number of questions: 62 

Time allotted to take exam: 2 hours 

Recommended preparation: Review the content below before taking the exam. 

ISC Virtual/Classroom:  

Online Learning:  

Recommended practical experience: At least 2 years of experience developing with InterSystems IRIS and a basic understanding of ObjectScript is recommended. 

Exam practice questions 

A set of practice questions will be provided here on March 3rd, 2025 to familiarize candidates with question formats and approaches. 

Exam format 

The questions are presented in two formats: multiple choice and multiple response. Access to InterSystems IRIS Documentation will be available during the exam.  

DISCLAIMER: Please note this exam has a 2-hour time limit. While InterSystems documentation will be available during the exam, candidates will not have time to search the documentation for every question. Thus, completing the recommended preparation before taking the exam, and searching the documentation only when absolutely necessary during the exam, are both strongly encouraged!
