94.1 percent of Vernon Hills teachers stay put; average earns $102,338 per year
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.
CHSD 128 full-time faculty members number 235, with a student-teacher ratio of 17-to-1. There are 1,335 students enrolled at the high school.
The average salary for teachers within the district is $102,338, ranking it eighth out of 859 districts in the state for pay. About 98.6 percent of teachers at the high school and 98.8 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.
