As an OCRES Certified Professional, you will be able to show future and current employers and clients that you know Real-time and Embedded programming specifications, making you a more attractive candidate for hiring and promotion.
The OCRES Program is the first and only objective, validated measurement of a candidate’s knowledge of Real-time and Embedded programming specifications. You don’t have to guess or try to test the candidates yourself. You can tell that an OCRES Certified Professional has made a commitment to knowing Real-time and Embedded programming specifications.



All of the OMG specifications on the exams can be downloaded from the Coverage Map page.
The Book is Software Engineering for Real-time Systems by Jim Cooling, ISBN 0201596202 - You can get it at Amazon, Barnes & Noble and many other booksellers.



The OCRES Certification Program includes three exams – the OCUP Fundamental Exam on UML, plus the OCRES  Intermediate and OCRES Advanced Exams. Look here for a diagram showing how the OCUP exam fits into the OCRES program. Each OCRES examination tests a candidate's knowledge of different Real-time and Embedded specifications and knowledge.
You should start with the OCUP Fundamental, because passing it is a prerequisite to getting certified at OCRES Intermediate, and passing OCRES Intermediate is a prerequisite to getting certified at OCRES Advanced. So, the real question is - how high should I go? That will depend on the skillset that you have or are learning. Look here for a functional description of the skills that each level of certification indicates.
No, you are not required to take the exams in a particular order. However, you won't receive an OCRES certification until you've passed all of the exams for its level.
Look at this Coverage Map to see what is covered in each Exam.
In the United States, the cost to take an OCRES examination is US$250; in many countries where English is not the first language, the testing time will be a half-hour longer and the price will be US$10 more (that is, US$260 or the approximate equivalent in local currency. Currency conversion does not track short-term fluctuations). You have to pay each time you take an examination, even if you're taking an examination over because you failed the first time. Payment is by major credit card. For exact pricing in your country, please look on the Pearson VUE test site.

These are computer-based tests, which you take on a computer at a test center. On the day of the test you go to the center, present (2) two forms of identification, and sign in. You will be escorted to a quiet room with one or more testing stations. You won't be allowed to bring anything into the room with you but your wits and a wipe off note board. You'll sign onto the computer and the test will begin. You will be required to complete an agreement promising not to reveal the contents of the test. The questions themselves are variations of multiple choice formats. The Exams last 90 minutes.
You should arrive at the testing center at least 30 minutes before the test is scheduled to begin. During that time you will provide proper identification and the test center administrator will give you a short orientation and then escort you to a workstation. If you do not provide appropriate identification, you will not be allowed to test for security reasons. Late arrivals will not be admitted.
You must have (2) two forms of ID, one with a photo and both with a signature.
Acceptable forms of photo identification include:
  • Driver's license
  • Passport
  • Military identification
  • Employee identification card

Acceptable forms of non-photo identification include:
  • Credit card
  • Check cashing card

In the U.S., Social Security cards are not considered acceptable forms of identification. 

The Exams must be administered at authorized testing centers.
You may bring your identification, but not much else. No computers, PDAs, cellphones, pagers, books, notes, scratch pads, writing instruments, coats, jackets, backpacks, briefcases, purses, and so on.
HERE Some centers may have lockers, but they are usually small, and there may be none available when you take your Exam. Please do not bring personal items to the test center.
No. There may be candidates taking other professional exams at the same time using the computer-based delivery system technology.
Yes. When you sit down to take an Exam at the test center, you will be asked to agree to keep the contents of the Exam confidential and to accept some terms and conditions relating to the Exam and your certification.

Yes, you may mark certain question that you feel are difficult and review them at the end of the Exam. After you clicked the submit button, the tool will tell you that you have marked questions and allow you to jump to them. Both marked and unmarked questions will be scored when finally submitting the Exam. Unanswered questions will be marked as incorrect answers.
The Exams are not scored negatively. This means that you can safely guess answers, as no points will be deducted for incorrect answers. It is best to check if you have actually answered ALL questions before completing the Exam. If you are running short on time, just click any answer and move on. This way, you will at least have a chance to get some of them right.

Once you have completed an exam online at a Pearson VUE Testing Center, your score will automatically be displayed on the screen. You will also receive a printed copy of the score report. This information is transmitted to OMG for our records.



No training is required, and you do not have to take or complete any training course before you take an Exam. Of course, we strongly advise that you prepare for the Exam by studying the Real-time and Embedded specifications and textbook sections listed in the coverage map, and have a general knowledge of distributed real-time and embedded application design and development.
There are numerous courses and books available to help you learn Real-time and Embedded specifications and knowledge. To find courses, you can start at OMG's Training Listings page. You can also look for books about learning Real-time and Embedded programming at bookstores.
At this time, practice exams are not available.
The minimum passing scores are in the description of each Exam, linked here. We do not release information on pass rates.



In most cases, you will receive your score report immediately after the test is completed. At the same time, you will receive some diagnostic information, to show you how strong you were in various areas.
First, Congratulations! You will have received your score at the test center immediately after you finished your Exam. If you have passed all of the exams required for a certification level, we will send you (by mail) a certification kit, usually within one month after you pass the Exam. The kit will include a letter explaining the certification, the actual certificate (suitable for framing) and instructions for downloading the OCRES logo for the level of Certification that you have passed.
If you fail an Exam, you can retake it after a minimum of 30 days, but you cannot take a particular Exam more than three times in a twelve-month period. The diagnostic feedback that you will receive with the test score report will indicate the areas that need further study.  There is no discount price for re-taking an Exam. The fee is the same as for the initial Exam.
Candidates who qualify for OCRES certification may use the OCRES Certification Logo for their level (Intermediate or Advanced) as a graphic symbol to demonstrate to clients their expertise with Real-time and Embedded programming specifications. Please follow these guidelines to correctly promote your relationship with OMG and protect the integrity of the Logo:

You may use the Logo on your business cards, letterhead stationery, resume, Web site, and marketing materials for individual service, to indicate that you have earned a credential in the OCRES Program. You may not use the Logo on any product, book, or other material. You may not use it for any purpose other than to designate your OCRES certification credential.

You may use the OCRES Certification Logo only as permitted by the OMG Trademark Usage Guidelines at http://www.omg.org/legal/tm_guidelines.htm. Some of these guidelines are:
  • You may not alter the Logo in any way.
  • Your name, trade name, or company name must appear on any materials where the Logo is used. The Logo cannot appear larger or more prominent than your name, product or service name, trademark or service mark, logo, or trade or company name.
  • OMG may, in its sole discretion, terminate your right to use the Logo at any time.
OMG will re-issue a lost certification kit for a pre-paid fee determined by location and shipping costs. Please send an email to certificationinfo@omg.org with the following information:
