I also live in Cowes and I am a teacher. The reorganisation is finally reaching completion so from tomorrow (!) we now only have primary schools for Reception to Year 6 and then all the 'old' high schools have become academies.
I imagine for your Year 7 child, Cowes Enterprise College is probably the obvious place to start. All the new schools are untried or tested but promising great things. The alternatives would probably be Carisbrooke and Medina - the new Head at Carisbrooke has been in place since June and has already done a lot of sorting things out! The County Press last week published results for A levels to give you an idea of how the high schools achieved - GCSEs will be published on Friday. If you have done your research, you will already know that results here are not great by a long margin!
Ryde School is the private school and a possibility that we consider for our DDs when they reach secondary level.
Within Cowes, at least now you can hope to get your other three DCs into one school although places in Cowes Primary, Northwood or Gurnard may be limited - you will have to check. We only have priority areas here on the island rather than catchment areas so that can make a difference, and it may depend on where in town you have moved to.
Northwood and Gurnard primaries are very good, village schools. Lots of people from town send their children there. Gurnard will be on split sites for a while before it all moves to the old Solent Middle School site on Baring Road. Until then, Gurnard and Northwood would probably require you to drive your DCs to schools, depending on where you live.
Northwood has a new, young head who has brought it lots of great ideas to what was already a good school. Gurnard has an excellent head who has been there for a long time and the school has always been well-thought of. Its new deputy head was previously head at Solent Middle.
Cowes has also recently had a new head - she will just be starting her third year there tomorrow. The deputy was recently announced too. They have a very active 'club' scene with lots of gardening, school goats, chickens and fresh meals provided by a private catering company and proper crockery! Standards, again, like Northwood and Gurnard are good.
I have left Love Lane - newly named as Lanes End - until last. If the other schools are full then this is the under-subscribed school. Historically it has struggled but I think it is now really going places. After too many different heads in too short a time, they have now had the previous head of Cowes Primary in place for the past year in a permanent position. She is really bringing a creative atmosphere to the school, getting parents involved and I think, personally, that this school may well turn out great. I appreciate that this may not be your first choice of school but to feel that, if it is the school you get, then it will not be a bad thing IYKWIM!
Last year all school apart from Love Lane were over subscribed. Love Lane is now 2-form entry which makes a difference to the allocation of places too, I imagine.
For Faith schools, Christ the King College (CKC) is the secondary school for you and has a catchment of the whole island - is was formed from the fairly recent amalgamation of two Middle Schools (Catholic and CE) and has moved solely to Year 7 onwards.
Holy Cross Catholic Primary is in East Cowes - don't know much about it but is small and friendly!
For the nearest CE, I think you are probably looking at Newport CE Primary - which again, I don't know too much about but it is very well thought of locally and I have heard lots of (only) good things about it from working in a school nearby!
Sorry for the essay but thought I would just give you some ideas - as a parent and as a teacher.
Good luck in finding places for your DCs, I hope you are enjoying living here on the island - feel free to ask if you have other questions - we have been here since 2005 and now have 2DCs.
