And he accomplished all this while attending high school, inching pragmatically closer to his goal of climbing a ladder and saving lives from a burning high rise.
"I'm stoked," said Busch, 18, of the pending days to graduation and of the pursuit of his dream. "The classes were so cool. They taught me all sorts of great things. We went over scenarios on what to do. We went over combustible materials. We did all that good stuff."
Regional ROP classes were created in the 1970s to teach students various occupations. In Busch's case, his classes in particular taught him not only about the here and now but what he needed to do to realize his goal.
And he's not the lone recipient of the program.
More than 13,000 students take a total 75 classes available to them in five school districts across Orange County, including Newport Beach, Irvine and Tustin.
The classes run the gamut from dance, floral design and nursing to auto technology, crime scene investigations and principles of engineering.
You name it, and the program is probably teaching it, either after school or during school, said Stacy Robison, a career specialist who works closely with Linda Kannow, the program's director of student services.
On Thursday, the pair was proving the real-life benefits of such classes, which bubbled forth in Busch, who entered the program with some trouble concentrating.
"Until you see it and hear their stories," Robison said, "you don't really have a clue what's going on. It's amazing what some of these children have accomplished. They grow up in a span of a few classes, and you see it right before your eyes."
