My two girls aged 5 and 7 (Years 1 and 3) go to Parkgate House and absolutely love it. It's a small school and definitely has that family feel to it, all the teachers know all the kids by name which is lovely. Also, they focus a lot on pastoral care and building up students' resilience, in fact the headmaster developed a resilience scale which now has been published and is being used by other schools across the UK.
They offer various clubs (Drama, Sports, Handwriting, Science, Arts, Coding etc.) and also offer a daily Early Bird and After School Club. Ballet/Karate, Arts, PE, Music, Drama etc. are all part of the curriculum. Unfortunately they don't do Swimming and Horseriding at the moment due to Covid restrictions but that would normally be once a week.
They offer warm school lunches but you can also bring your own. They give the students lots of opportunities throughout the school year to speak/perform in front of the class or whole school and during parents' assemblies and they absolutely love the shows they're putting together! The staff are lovely and very caring and due to small class sizes every student gets individual care and attention.
What my girls particularly enjoy is that the year groups are interacting with each other frequently so not only do they get to know their peers but also the younger AND the more senior students throughout the school.
They have a "house" system, each student is part of one of four houses. They are competing against each other during the whole academic year, do different challenges and are collecting house points individually as well as in teams. The house points are being announced by the head boy or girl during the weekly assembly. The winner gets the trophy which is always a very big deal!
One of the negative points to consider are facilities. Due to its small size, they don't have any sports facilities. They're using the Common a lot and ballet/karate as well as assemblies takes place at the Devas on Stormont Road. There is an Arts room however, tiny but the kids like it!
I hope that was somewhat helpful, I suggest you go in for a visit, they offer individual tours I think.
Best of luck!
