The messages from schools in several cities describe compulsory displays of images of Iran's Supreme Leader Mojtaba Khamenei, increased classroom monitoring, enforcement of mandatory hijab rules and the presence of Basij forces.
Students at a school in Dezful were ordered to pose for photographs with two banners depicting Ali Khamenei, Iran's slain former ruler, and warned they could be expelled or referred to police if they refused, a student told Iran International.
In Marvdasht, education department officials visited a school on November 1 to inspect compliance with mandatory hijab rules, according to another student.
Students who failed to observe the dress code would be expelled, the school's principal warned, the student said.
A student in Tehran also described compulsory Quran recitations, saying school authorities had warned that those who refused would receive failing grades in core subjects.
Basij forces enter schools for military activities
Other accounts described the presence of Basij forces and plans for military exercises on school grounds.
Students at a school in Alborz province were informed that a missile launcher would be brought into the schoolyard and armed forces personnel would conduct a military drill, one student said.
In Lorestan province, students at a school for gifted children were taken to apro-establishment rally on October 28 without their parents being informed in advance, according to a family.
Iran International earlier reported that students in six provinces had faced pressure to participate in Jan-Fada (Self-Sacrifice), a system-backed initiative involving military training and mobilization activities. Some students were warned of expulsion or consequences for their parents if they refused to take part.
Basij members visiting another school instructed students to stay out of politics, according to a student who described the exchange.
"How can we stay out of politics when we have lost more than 40,000 brothers and sisters?" the student said in response.
Another citizen described seeing a group of students on the streets wearing camouflage uniforms and military-style scarves and carrying batons.
Military equipment and activities in schools have featured in earlier accounts received by Iran International.
Based on earlier reports, students at some schools had been given identification tags or instructed to obtain and wear them.
Other accounts described armed personnel and military vehicles entering schools and children receiving weapons training.
The Education Ministry's spokesperson denied reports of military identification tags being issued to students on October 23, saying school principals were not permitted to announce measures that could cause concern among families.
Schools increase surveillance and restrict gatherings
Surveillance cameras in classrooms at a public high school in Tehran's District 19 doubled on October 28, according to a student.
Previously, a single camera had been installed at the front of each classroom facing students. Another camera has since been added behind them, the student said.
In Gonbad-e Kavus, northern Iran, school officials prohibited students from gathering in groups of more than two, according to another account.
The restrictions follow similar measures documented in an earlier report, when students from several cities described classroom cameras, audio recording, searches of personal belongings and clothing inspections.
Another student described armed officers accompanying a school excursion to a park and repeatedly instructing high school girls to comply with hijab requirements and wear their headscarves properly.
