It has been a time of change for Isaac Touitou, headteacher of the Daniel Mayer-Montreuil ORT school. He has lost 30 pupils who have made aliyah to Israel, but in the past fortnight he has gained nine new recruits - soldiers.
The unusual development has two key causes: one is the Jewish school's location, just a kilometre from the site of the Hyper Cacher attack; the second is the growing trend among the 800 students aged 13 to 26 to leave the country.
The nine soldiers now living on the school premises are part of the temporarily increased security measures. They are on-site 24 hours a day and even sleep in the school building.
Pupils are no longer allowed out of the grounds at lunch time, and the school has had to create a smoking area in the courtyard to stop students and staff venturing out onto the street. All school trips have been cancelled.
Father-of-three Mr Touitou said: "People feel very angry, but not very surprised. They are worn out.Every time an attack happens there is a peak of emotion which then peters out and things go back to normal.
"The questions about the safety of Jews in France and whether we should go to Israel are ones that we ask ourselves all the time."
Mr Touitou said the majority of families making aliyah in recent years had been motivated by safety concerns.
He sees the effects around the school. Since the Toulouse school attack in 2012, two members of staff and 30 students have gone to Israel.
The upper-sixth form class originally had 20 pupils but one fifth have left.
"A new trend I think we will see over the coming months is students leaving for Israel alone, without their families, after their Bacchalaureats, to continue their studies in Israel," he said.
In some cases, families or students have made aliyah but quickly returned to France because of problems finding jobs and integrating into Israeli society.
The school has developed new partnerships with Israeli universities such as the University of Hadassa, which will now recognise the ORT diplomas and accept transfer students.
