I disagree, my problem with Catholic Schools is due to poor experience with the Jesuit ones I attended, they just were not staffing quality teachers (not surprising when they pay teachers $10k a year less than public schools) and each Archdiocese does things differently.

The Seattle Archdiocese has created a haven for spreading diseases unheard of in public schools by not encouraging or requiring vaccination of students. The other nearby archdiocese do not permit unvaccinated students to attend, and haven't had repeated outbreaks of once banished diseases.
