What Causes Burnout? All of The Above is an insightful post from John Thompson that describes some research findings that, in his words, “show the interconnectedness of conditions that produce the achievement gap.”

Here’s another quote:

“Among teachers with less than 1% of students with limited-English proficiency, less that 1/4th have 25 students or more per class. Among teachers with more than 10 limited-English students, nearly 1/3rd have more than 25 students. The same pattern applies to teachers with more than 75% minority students; it is the teachers with the bigger challenges who often have the most students.”

His post is definitely worth a look.
