My daughter is currently at an all-girls school that is quite small (one form entry). She is very happy there. My son goes to an all boys school just round the corner. It is a much bigger school (2/3 classes per year).
The boys' school is going co-ed and we have the option of moving our DD to the new co-ed school from September this year. We are trying to work out what to do.
Pros for moving are: easier to have both children in same school, the (currently) boys' school has amazing facilities and arguably more academic. We always had reservations about whether DD's school was going to work for her all the way up to Y6 as they have more limited e.g. sports and drama provisions due to smaller numbers. We also have reservations about the future viability of the girls' school given they now have co-ed competition which they didn't have before.
Cons for moving: the teacher our daughter would have next year is exceptional (the options of who she would have as a teacher at the boys' school are fine, just not exceptional). She would be one of a very few girls in the school.
At the moment, for DD's year group there are 6 girls (including DD) interested in starting at the boys' school in 2026 (3 of whom DD is currently in a class with at her current school). We know one is definitely not going to move, two have already confirmed that they will move, 1 likely to move move and 2 (including us) on the fence). So best case scenario is that there would be 5 girls and around 35 boys in the year. They would likely put all the girls in the same class together.
At the moment we are thinking of staying where we are and seeing how the move to go co-ed goes, with potentially increased girl numbers for 2027. We can then reassess things in a year's time.
We literally just keep going round and round in circles about the best thing to do!
