The Illinois State Board of Education records data concerning faculty salary, retention and attendance because maintaining a stable faculty makes for a better environment for teachers and students, furthering student success, according to the report.
Northfield Twp HSD 225 full-time faculty members number 358, with a student-teacher ratio of 16-to-1. There are 2,972 students enrolled at the high school.
The average salary for teachers within the district is $100,135, ranking it 12th out of 859 districts in the state for pay. About 89.6 percent of teachers at the high school and 84.2 percent of those in the district were absent 10 days or fewer in 2017, compared to 75.3 percent of teachers in the state.
Salaries vary depending on the school and district, as well as the teacher's level of experience and education, according to the report. The U.S. Department of Education considers teacher attendance a "leading indicator" of how well students perform. When a high rate of teachers are absent more than 10 days, data shows students perform worse.
