It's not just kids who are headed back to the classroom this fall. If you're looking for a way to increase your job security and give your salary a boost, why not consider taking an engineering training course from the comfort of your own computer? The Engineering Training Series features ongoing Web-based classes presented in association with leading engineering schools.

Participants can earn Continuing Education Unit (CEU) credits for all classes, with each course presented as a one-hour seminar by an expert instructor. Dates listed represent the first day the course is available; all classes are archived online for two months, and CEUs can be earned by viewing either the live or archived program:

• Overview of Hydraulic Systems, Construction and Operation - Oct. 4

• Introduction to Hydraulic Fluids for Industrial and Mobile Applications - Oct. 11

• Contamination Control Fundamentals - Oct. 16
