It's pandering to the paranoia that Jewish people so enjoy revelling. I live in a Jewish area. I used to be an Israeli. I know all about it. The Jewish culture is suffering from a pathological love of feeling under threat. We have been indoctrinated with fear of the goyim and this indoctrination is in service to the genocidal state of Israel which has used the former victimisation of Jews in order to create a fascist, racist, evil society and ideology.
The Jewish community feels empty without antisemitism and inflates the feeling of risk, it stimulates fear in young kids, it encourages them to believe the "everyone is against us" mentality. It's sort of like a mental illness as applied to a culture. Is there a term for that?

The fact the school has security staff does not prove there's a risk. There is a fetish in the Jewish community for employing ex-Golani psychopaths. The trauma of the abuses of Jews in the past is being used to empower Israeli political aims. Jewish people are not under threat yet they support the revolting state of Israel which is one of the most brutal states in existence. Jewish people are not under threat but they applaud the bombing of Gaza, the murder of women and children. Jewish people are not under threat yet they all jump up and down about antisemitism when it's being used to serve the political aims of those trying to undermine democracy.

Jewish schools are hotbeds of indoctrination. For what it's worth, I think all schools are. Having the whole security theatre and teaching kids to have a relationship with a foreign country that has nothing to do with them, teaching Zionist ideology, it's all crazy. You teach in a Jewish school. Hah. If you're not Jewish, you should be able to see the bullshit for what it is. If you are Jewish, you won't be able to understand your own indoctrination unless you are already open to the undermining of your cultural programming.
