A new survey has found that over a third of teachers can be described as “disgruntled,” while the rest of teachers fall into the category of either “idealists” or “contented.” The survey, conducted by Public Agenda, showed that 40 percent of teachers respond positively to statements like “teaching is so demanding, it’s a wonder that more people don’t burn out,” and show high frustration levels with their jobs. Those who fall into this group tend to have been teaching for longer and in low-income schools than those who fall into the two other categories. Only 14 percent of “disgruntled” teachers rate their principals as “excellent,” and they are more likely to voice frustration with disorder in the classroom and an undue focus on testing. On the other hand, the 37 percent of teachers who the study finds “contented” are usually teaching in middle income or affluent schools. Many of the 23 percent of teachers labeled “idealists” report they plan on leaving the classroom for other jobs within education. “Idealists” report that helping underprivileged children improve their lives was a motivating factor in becoming a teacher.
