i dont know about other counties or even other schools in Calvert Co, but the school my daughter attends, if there is a trip that the class is taking, there have been times where the school provides the funds for the trip if there were children that couldnt go due to financial constraints. thankful we've never had to ask for assistance from the school, but there are MANY who have that need. bless the teachers and administrators that cover the cost. i THINK some of the money may come out of a special PTA fund or something, not sure how they do it, but they do it. if a childs parent signs the permission slip that they are allowing them to attend, but simply cannot cover the financial burden, the school covers it. amazing!
