teachers from an education college are pretty similar, aren't they?
Leaving So Soon?
MULTIMEDIA: First Person: Keeping Teachers Teaching
Every year, U.S. schools hire more than 200,000 new teachers for that first day of class. By the time summer rolls around, at least 22,000 have quit. Even those who make it beyond the trying first year aren't likely to stay long: about 30 percent of new teachers flee the profession after just three years, and more than 45 percent leave after five (see charts, below).
(These stats are different from some other's I've read that have attrition at about 50% the first three years and 60% after five... though maybe that was a particular state...)
What's more, 37 percent of the education workforce is over fifty and considering retirement, according to the National Education Association. Suddenly, you've got a double whammy: tens of thousand of new teachers leaving the profession because they can't take it anymore, and as many or more retiring.
When teachers drop out, everyone pays. Each teacher who leaves costs a district $11,000 to replace, not including indirect costs related to schools' lost investment in professional development, curriculum, and school-specific knowledge. At least 15 percent of K-12 teachers either switch schools or leave the profession every year, so the cost to school districts nationwide is staggering -- an estimated $5.8 billion.
Students from the lowest-income families suffer the most. Inexperienced teachers (those with less than three years on the job) frequently land in classrooms with the neediest and often the most challenging students. Beginning teachers frequently start their careers at hard-to-staff schools where resources may be scarce -- in other words, urban schools -- simply because there are more jobs available there.
