My friend had her 3DC in private school. All three started at the age of three. Financial problems started through no fault of their own as eldest approached GCSE. School initially accommodating. 12 months later, financial situation bad & informed school about payment agreement (via). At this point 2nd child due to start sitting GCSE' s, school suspended son week before exams began. Child did not do as well as expected. Insisted on charge on property to ensure weren't part of payment plan.
Her children had represented the school well, both academically & in sport . They felt deeply betrayed. There was no legal solution as private schools don't have to follow education laws. She later discovered that the boy who sat his exams couldn't concentrate while there,cos he kept expecting to be pulled out in front of his friends. I appreciate its,a business but they sell themselves aspurveyorsodeducation that sometimes they can't deliver.
Her kids then went to local state school & flourished. Private schools don't always provide best (ie dyslexia, problem solving). This particular private school is selective & regards itself to be amongst the best.
When I asked my friend if she would do it,again (ie, pay) she said definitely for junior school, not for seniors as her kids benefited from the help provided.(I would point out, her kids are bright & would probably have achievedsucceedewherever they went)
It was a deeply stressful time for the whole family.
I never went down that route & my kids have all done fine. Think very very hard about this commitment & best wishes for what ever you decide x
