Jeni Callan sits near the front of the school bus, listening and taking tidy notes on a legal pad.
It’s new teacher orientation day in the Hamilton School District, and the yellow bus carrying nearly 30 new hires for the 2011-’12 school year is winding through Waukesha County as the district’s spokeswoman shouts out the history of each passing school.
Callan, 26, is about to start her dream job as a language arts teacher at Templeton Middle School and knows that her good fortune is partially attributable to an unusually high number of retirements in Hamilton at the end of the school year.
But the job market has not been so kind to other young educators hunting for work, especially those lacking credentials to teach in specialty fields such as special education, math or physics.
“This is maybe the most unusual hiring climate for teachers that I’ve ever seen,” said Bill Henk, dean of Marquette University’s College of Education.
