Prohibiting certain sex offenders from entering onto school property or attending school activities and creating criminal penalties for violation thereof.

SB 288 prohibits adult sex offenders (18+ years old) who committed crimes against minors (victims under 18) from entering school grounds or attending school events in Kansas. It creates criminal penalties for violations: a first offense is a severity level 6 felony, escalating to level 3 for third or subsequent offenses. The bill amends Kansas' offender registration law to include this school access ban as a specific restriction. This directly affects individuals convicted of sex crimes where the victim was a minor, as defined under Kansas law.
