Because of its reputation as a feeder to SPGS, although that isn't true, they attract very ambitious, pushy parents. Some of girls arrive at school in Y3 with an attitude 'I am a SPGS material, but you are not.' Obviously the attitude comes from their previous school environment and/or, of course, from their tiger parents. Bute hates it. GIrls at Bute will be educated to run their own race and celebrate each other's achievement in a less pressured, happy environment. So will parents.
There are no formal tests, no ranking, no academic prizes, no ridiculous badges etc, unlike some other preps in the area.Parents are informed which quartile their daughter falls into, only once a year. CAT scores aren't shared with parents.There is an acknowledgement among girls who is academically super or less so, but they don't talk about it because it's not a competition. Or at least they try not to. Parents are also told not to 'gossip' about it. While sports and music are very competitive and can be boastful, they are quite low-key in terms of academics.
Head's advice regarding senior school choices is about the likelihood that your daughter will settle well and thrive there. Some girls leave SPGS after a while because it wasn't a right school for her. SPGS is not for everyone after all. Parents' pushiness of getting their daughter into SPGS will be well diluted by the time of 11+, and they look at schools
where their girl will be happy and thrive, which is not necessarily based on the league table position. Again, many of parents were very ambitious, competitive and result driven at the start, then changed their view over their time at Bute.
It might be hard for prospective parents to see how their non-academic competitive ethos work, and even some of current parents might be in doubt, but the parents who went through the process know it works. They try removing all sort of toxic that competitive environment could bring to the community e.g. boasting, jealousy, bulling, vicious rivalry etc, and to help the girls reach their potential in a happier way. Bute is excellent for that reason, not for the number of offers their girls get from well regarded schools.
As for lack of feedback, it could lead to over tutoring because parents aren't sure if their daughter is on a 'right track' to their preferred schools. This may be a negative impact of the ethos.
