tvt: The parents should always be asked NICELY first why they aren’t meeting their chov to the school, and if they really can’t afford it (eg: loss of job) work it out after the school year is over. Obviously an araingment had been made at the beginning of the year or the student would not have been let in. Facts on the ground changing in the middle is not a reason to kick a child out in the middle of the year, as the child will not cost them any additional money to remain (since the spot is already taken). “Embarasment tactics” should only be used after asking a non-nogaih Rov, (from outside the community) and only in cases where there is no reason why the family stopped paying.
Anon: In your case, I would of considered home-schooling, since the school was obviously taking advantage of those who supported it.
