2017 UPDATE!

CCE – NAHLE recently revised our Certified Chief Engineer (CCE) training program for hotel engineers and maintenance professionals. Our new Learning Management System (LMS) now provides an online version of our select-service study guide in addition to the printed copy they receive. Among other new features, engineers may now take a Practice Exam after reading each individual chapter before moving to the next chapter for study or they may choose to take all of the practice exams for a section in one sitting similar to the Section Exams they are required to pass.

According to Robert Elliott, executive director of NAHLE, “Our CCE exams are now administered from a new LMS software platform. Though, we still work with the AHLEI and are grateful for their initial input and guidance, we find Litmos’ Learning Management Software (LMS) offers several new features and benefits. For example, we recently provided a free webinar on combatting bed-bugs in hotels. NAHLE recorded the webinar and we are able to provide a video file as a supplemental reference to our chapter on Integrated Pest Management. Another feature worth noting is our ability to generate automated progress reports for hotel management companies with multiple engineers in training. Our training focuses on the hotel’s many assets and building systems as well as the engineer’s professional development in areas such as fire safety and time management, among others. I am really excited about the possibilities with our new LMS and look forward to getting a Spanish version for the CCE completed and online. One of our programs’ primary focus is to train the very person(s) that is responsible for maintaining these assets on a daily basis. Sometimes just having the knowledge to make the right decision of whether or not to try and handle something in-house or to seek input from a third party can have a tremendous impact on the useful life of that asset.” 

CDOE - The Certified Director of Engineer, NAHLE’s training program for full-service hotel engineers, is also now residing under our new LMS. The CDOE study-guide has also been revised to include a new chapter providing an overview of hotels and how they operate. We have also added an index to assist candidates in their study and as future reference tool to quickly find information on almost any hotel engineering subject. Currently in development, NAHLE will be adding two practice exams to match the two required Sectional Exams. The CDOE practice exams are also intended be used as a tool to help the candidate assess their knowledge going in and then as a comparison upon completion of the program.
