The National Center for Education Statistics released Characteristics of Public Elementary and Secondary School Teachers in the United States: Results From the 2015-16 National Teacher and Principal Survey, which is a long title for a relatively short report filled with useful stats on school staffing. Here are just a few:
* There were 3.6 million teachers in traditional public schools and 218,500 in charters. Almost 81 percent of traditional school teachers are white; about 71 percent of charter school teachers are white.
* In schools with less than 35 percent of students eligible for free or reduced-price lunch, 88.4 percent of the teachers are white. In schools with more than 75 percent of students eligible for free or reduced-price lunch, only 66 percent of the teachers are white.
* The average class size of elementary, multi-subject teachers was 21 students.
* Only 64 percent of teachers received any training in serving students from diverse economic backgrounds. Only 53 percent were trained on using student performance data to inform instruction.
