     Texico High School is renewing its professional arts program.

     For years, one teacher taught the professional arts and was in charge of the Future Farmers of America

and Leadership programs. This year, community and school leaders decided to give the professional arts

program more attention.

     The school decided to bring back the program after a survey of the students. The students wanted

professional arts classes. To lead the program, the school invited Terry Whitener. Whitener taught leadership

and professional arts in Anthony, Texas.

     "It is difficult to do both well," he said. Whitener took carpentry (木工活) classes while he attended Texico

High School. "There were a lot more activities back in the 1980s than when I came here this year," he said.

     The school has bought new equipment for the carpentry workshop for Whitener's classes.

     Whitener said the classes were to give the students a leg up when they left high school "Not all students

are going to college," he said. "Even if they do, this program gives them helpful skills." Whitener said he wanted

to teach students carpentry classes from a career (生涯) standpoint (立场).

     "Measure twice, cut once. I tell them no boss is going to want to pay them to do a job twice, when they

could do it right the first time," he said. "Traditionally, all the guys were going to be farmers. That's not true

anymore. More kids will use these skills in a career instead of on their own field."

     "This is something I'm going to do after high school," said Zayne Meeks, one of Whitener's students. "It

gives people better opportunities to get better experience and then a better job."

     Another student, Lucas Waltners, said he was unsure of what he wanted to do after high school, but that

the skills learned in Whitener's class would be helpful either way. "This is something I'll know how to do if I

ever need to do it," he said.
