lunch money I understand though when I just looked at our district's website it appears they have done free k-8th lunches for the past few years. no band or sports fees in our district (and they have some kind of arrangement w/a particular medical group to do no cost sports physicals). not sure if it's changed since but when mine attended (last graduated in 2017) I don't remember a single high school field trip (other than seniors no-fee to scout out regional colleges, no-fee participate in the lional hampton jazz festival) and a shift from traditional k-8th field trips to some kind of traveling field trip exhibits that came TO to school for several days and set up so more students could benefit at a lower cost (read-no cost to students).
I think all the fundraising is done through the boosters at games/concerts, maybe there's still the schoolastic book fairs? for those you paid when you handed in your order. I honestly have not encountered a kid doing fund raising for other than a private school in decades and it's not due to the fact I live ruraly-the city I lived in until 2007 in northern California had in the 90's illegalized minors door to door selling or soliciting funds (with the overwhelming support of the community) so the days of wrapping paper, cookie dough, popcorn....sales were long past (the schools got very creative and made much more profit with alternate fund raising).
stuff like caps and gowns I remember paying the company that provided them vs. the school, no fee for concerts (did'nt have any kiddos in sports but unless you were buying a semester or academic year pass you paid at the gate). not sure how popular AP classes are since students can take a dual credit at no fee.
dance fees? like going to school dances? those were all free (except prom) when my kids attended. no fees ever for holiday parties (what holidays are even celebrated in public schools anymore?) and while a supply list for items a student will PERSONALLY use and retain is permitted it's illegal to charge for anything like pet food, classroom supplies...
my kids were EXCEPTIONALY fortunate to attend a district that has tremendous backing of the community. a concerted effort is put forth to give every student equal access at no cost to every opportunity. to show the extent they go to-back in the recessionary 2000's when every school in our state was looking at ways to cut costs by making cuts whereever they could it was suggested that a large savings could be achieved by eliminating the m-f after school 'activity bus' that served the 300 square mile district but that idea was immediately struck down by the school board, parents and community members who rightly knew that most participants in the after school activities and athletics were entirely reliant on the busses as their sole means of transportation (rural schools-no way to travel to school except by school bus or private cars, no walkers or bike riders permitted due to designation of roads surrounding the campuses). some districts would have sought out a bond initiative but no one desired putting a financial burden on many households already struggling mid recession-other budget cuts were found, community fund raising efforts and private donations have continued that bus to this day.
