SPRINGFIELD, Ill. (AP) — Among several new laws effective in Illinois this week is a requirement that children attend kindergarten at a younger age, a shift that state officials say could mean higher costs for an already underfunded school system.

Most of the new measures that went into effect Tuesday deal with youths and schools. One requires young adults seeking driver’s licenses to take a training course. Another, prompted by the death of a high school girl during drill team practice, requires students to learn emergency life-saving skills.
