There will be a career fair this fall for Westfield's middle schools. But it won't be kids learning about what it takes to be a machinist, an engineer or an auto-body technician. It'll be their teachers. The idea isn't that educators are looking for new gigs themselves, said Kate Phelon, executive director of the Greater Westfield Chamber of Commerce. The idea is for teachers to learn what employers are looking for -- and what they hope not to see -- in job applicants, so they can impart those skills to their students as early as sixth grade.
