Red Hat has three major certifications for RHEL: Red Hat Certified System Administrator (RHCSA), Red Hat Certified Engineer (RHCE), and Red Hat Certified Architect (RHCA).

To quote the Red Hat site:

RHCSA is a subset of RHCE and defines the "slightly above entry level" sysadmin set of skill and Linux knowledge, a sysadmin without knowledge of scripting, but with solid knowledge of classic Unix utilities and command line, as well as booting process, basic networking and somewhat deeper understanding Red Hat idiosyncrasies. The holder of this certification is expected to possess the core Linux system administration skills (heavily tilted toward Red Hat, as you can expect ;-)  which gives him a possibility to install, maintain and troubleshoot servers with RHEL or CentOS installed.    To quote the Red Hat site:

As Red Hat states

An IT professional who has earned the Red Hat Certified System Administrator (RHCSA®) is able to perform the core system administration skills required in Red Hat Enterprise Linux environments. The credential is earned after successfully passing the Red Hat Certified System Administrator (RHCSA) Exam (EX200).

It focuses instead on such routine systems administration topics as well as RHEL installation and configuration. The required skills include

  1. Understand and use essential tools for handling files, directories, command-line environments, and documentation
  2. Operate running systems, including booting into different run levels, identifying processes, starting and stopping virtual machines, and controlling services
  3. Configure local storage using partitions and logical volumes
  4. Create and configure file systems and file system attributes, such as permissions, encryption, access control lists, and network file systems
  5. Deploy, configure, and maintain systems, including software installation, update, and core services
  6. Manage users and groups, including use of a centralized directory for authentication
  7. Manage security, including basic firewall and SELinux configuration

RHCE is the next level and approximately corresponds to senior sysadmin level of qualification. It requires minimal knowledge of scripting (just bash, no  requirements for Perl or Python.) You must be RHCSA to become RHCE. The number of topics is wider and complexity of problems is higher too and includes installation and configuration of some applications such as MySQL and Apache.  To you need to accomplish more in the same amount of time.

As a person who just returned from RedHat, after completing the RHCE course, I think I have to put forth my opinion to those who are making theirs known here. 

The RHCE training course is well-designed, well-rounded and complete with a mildly-difficult lab exam. The RedHat employees are friendly and helpful, the amenities are gracious and complete. Over all, the experience was great. 

The concerns that I and others in my class had regarding course material (ambiguous questions and the occasional too easy lab) were listened to by the Training Coordinator (Peter Childers, a very intelligent and good person) personally, and all concerns were met with questions that showed intent to change the course material to the better. The course is in a state of continual improvement, and each class will be better than the last. Soon, there may be divergent levels of difficulty to accomodate the wide spectrum of Linux users. This is a good thing. 

To those who believe that the RHCE is a bad thing, take the course and decide unbiasedly. You cannot shout from the rooftops to the Linux community (slashdot) about something that you have no credible knowledge of. Go visit RedHat and talk to the people there. It will surprise you to find how much work puts into the Linux community, that is outside the scope of RedHat. They evidently have their heads screwed on straight, they are out to make a profit (what company is not?) and are doing it the right way. 

In conclusion, I recommend that people of all skill levels go and take the RHCE course. If you are a knowledgeable user, the class will teach you quite a bit. If you are a very well versed Linux developer, you might not learn quite as much, but it will be a good experience, and it will confirm your knowledge, not to mention give you "RHCE" after your name. 


RedHat was one of the first Linux distributors that introduced a certification program. It is oriented mainly on corporate clients and resellers. The exam for RedHat Certified Engineers is $749 --  quite expensive (more expensive than all 6 Microsoft certification exams). Tuition is even more expensive ($2500) -- it is oriented on Certified Resellers, not Certified Engineers. But on positive side probably as there will be more and more RedHat Certified Resellers, more people would trust in Linux at the enterprise environment. So even if your cannot afford it and/or your company will not pay for it, it makes sense to prepare yourself for this exam, anyway.

RH considers training as one of the most important avenues of growth (see Dan Barkin A price of going public and For a company that had almost no money two years ago, Red Hat has made a tremendous progress. It now has more than $10 million in cash (mostly from preferred stock sales). The IPO is expected to raise a hundred million dollars. 

And Red Hat plan to spend a lot of them for building-up of its training program. Red Hat's needs to convince investors that it has a strong business model based on impressive market share, while assuring Linux fans that it's not like "some other companies." 

Until recently the company has grown very quickly: from March 1, 1998, to the end of last month, its work force tripled (from 36 to 127). Now Red Hat is paying $900,000 a year in rent -- nearly as much as its revenue in 1996. In the fiscal year 1998, Red Hat had revenue of about $10.8 million, much of it from sales of its retail boxes. Whither this revenue stream possess big potential for growth remains to be seen, but the company clearly need a diversification and training is a perfect candidate here. 

The course includes 4 days of training and 1 day Certification Lab Exam. The course and certificate are based on Red Hat Linux 6.0.

RH recommends that all prospective RHCE participants review prerequisites in preparation for the course and exam.
