The Ministry of Science, Education and Youth announced the changes two weeks after a 19-year-old former student fatally stabbed a 7-year-old girl and injured four others, including a teacher.

The attacker, who was receiving psychiatric treatment, carried out the assault on December 20.

Under the new rules, schools must lock their main entrances 30 minutes before lessons begin and reopen them only 15 minutes after classes end. Staff on duty are tasked with monitoring students and reporting any “unusual behavior.”

“Parents may enter the school premises only at a prearranged time or upon invitation from the school,” says the document.

Identification will be verified using photo ID, and “entry will not be permitted to individuals who refuse identification.”

Schools are also authorized to inspect bags and clothing of students and visitors both upon entry and during lessons.

“Individuals refusing inspection will not be permitted entry into the school,” says the document.

Evacuation and crisis drills will now be mandatory twice a year to prepare staff and students for emergencies.

The December attack has sparked a national debate about school security and mental health services. Authorities have described the measures as a necessary response to safeguard the country’s schools.
