Exactly. I see many schools with higher “grades” than UCB (for example) that have lower ratings that relate to the university’s own policies and strength of Jewish life, but simply don’t have as much protesting going on.
However, some students and families may specifically want to avoid schools with a lot of anti-Israel protesting that may border on (or veer into) antisemitism, and might not care quite as much about Jewish life or specific university policies. Or they may be looking for one of the (few) schools with high ratings on every section. It is up to the student what they are looking for. They may find value from this resource if they look into the details.
