78 percent of Mark Twain teachers stay put; average earns $44,555 per year

The Illinois Schools Report Card finds that 78 percent of teachers stay at Mark Twain Elementary School year to year, according to their 2020 three-year average.

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.

Charleston CUSD 1 full-time faculty members number 168, with a student-teacher ratio of 22-to-1. There are 232 students enrolled at the school.

The average salary for teachers within the district is $44,555, ranking it 895th out of 1096 districts in the state for pay. About 70.9 percent of teachers at the school and 70.9 percent of those in the district were absent 10 days or fewer in 2020, compared to 86.6 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.
