Jamila Williams, 36, pleaded no contest Sept. 19 in Kent County Circuit Court to four counts of criminal sexual conduct. A no-contest plea isn't an admission of guilt but is treated as such for sentencing.
Authorities said Williams had sex with two 15-year-olds and two 16-year-olds. She worked at the Grand Rapids University Prep Academy, part of the Grand Rapids Public Schools.
In court Tuesday, Williams apologized and asked for forgiveness, but said she didn't "prey on" the boys.
Judge Paul Sullivan said the harm Williams brought to the school, students and her family is "incalculable."
