This article is correct, though I don't think the author spells out the problem well enough. The problem is that schools hire "teachers" who do not teach. They hire "teachers" to run special enrichment programs, when they need to hire teachers to accept responsibility for classrooms full of students. An average elementary school with about 125-150 students in each grade generally has about 5 extra teachers and 10 extra "assistants" who float around, accomplishing little. If they put the 5 extra teachers in classrooms and replaced the 10 assistant with 5 more teachers, they'd reduce average class size from 25-30 to 18-22. Given the budget cuts, eliminating half and sending the other half to classrooms makes the most sense.
