I sent my son to a Catholic elementary school, and he is now in 10th grade at a Catholic high school, and he may well attend a Catholic university. Who knows?
I speak as a member of the parish council/school commission at my school for many years that the amount of tuition that a family pays doesn't begin to pay for the expenses associated with educating their children. Raising the tuition by $100 per year wouldn't begin to cover it. A large percentage of the Sunday collection at parishes that have schools goes to paying for the schools, just every day expenses, like teacher salaries, heating the school, repairing the roof, and so on and so forth. As a parent and as a leader of the parish community, I would love to see all of my fellow parishioners able to afford to send their children to our parish school Different Catholic schools have different models for charging tuition. One parish in the area used to not charge active parishioners any tuition. Over time, they needed to switch to charging tuition, because there were people who weren't paying a fair amount into the collection to cover their share, since, technically, the parish can't put a dollar amount on what contribution constitutes an "active" parishioner for tax purposes. Contributions to the church are deductible; tuition is not. Childcare after school is deductible, school day expenses are not. At our parish, parishioners were charged one level of tuition, and non parishioners were charged more, but, not even the higher amount covered the expenses, which are thousands more than the tuition. So, parishioners, in effect, who don't have children in the school are subsidizing the education of those who aren't parishioners.
My schools parent organization would sell supply bags for each grade, and I know that we paid a fair price, even if we bought crayons and markers when they were on sale at Target for $1. I thought it was a great convenience to me as a parent, in much the same way the
Disney Dining plan is a convenience, and doesn't necessarily save me money, but, I am never far from breaking even.
But, people who are parishioners who support the school do so much more than give money to the fundraisers. We paint the school rooms during the summer. Parishioners who are electricians and roofers donate their time to do those repairs. We have an silent auction, and I donate my DVC points to earn money for the school. My husband and I judge the science fair.
I respect the teachers at my school, and I think they deserve fair pay for the work that they do, and shouldn't have to spend their own money for supplies for the classroom. I would personally be mortified if I knew this to be the case in my son's classroom. I have donated tissues, tylenol, bandaids, etc to the school, way beyond what my son might have used. Yes, some parents may not have sent in their share, but, at least the kids and teachers have what they need.
