Extends limitations on expulsions and suspensions for young students to students in grade three.

This bill extends New Jersey's existing protections for young students by expanding the grade range covered under restrictions on school expulsions and suspensions. It prohibits expulsions for students in kindergarten through third grade (previously only through second grade), except for gun-related offenses under the "Zero Tolerance for Guns Act." It also bans out-of-school suspensions for these grades, except when the conduct is violent or sexual in nature and endangers others. These changes directly affect all public and charter school students in kindergarten through third grade across New Jersey.
