is dual schooling possible?

I think that would be very difficult as the spanish public ( state) school system would require that he become proficient in Spanish and 1 month on 1 month off wouldn't be sufficient to learn and follow the tough Spanish curriculum. 

Also I think it would be classed as absenteeism, to miss a whole month of school at a time, good schools have competition for places and I dont think any public school would want a child attending 1 month on 1 month off when they could have another child continually. Not to mention no continuity in education for the child. What you're thinking of doing would be a massive challenge for a 6 year old.

The only way it might work would be to get your son a place at a private British school that follows the UK national curriculum, that way he would have some continuity in his education and as you would be paying fees you probably wouldn't lose their place. You would have to find one that would agree to this. 

If you go for a private international school then they would be expected to do homework when they weren't in spain in order to keep up with their peers and the curriculum. Children are tested a lot in spain and can be kept back if they fail certain stages of their primary education. 

thanks for the response and i understand it wouldnt be ideal.

i agree if he was having 1 month off/on he would fall behind but he would be having a Spanish tutor to help his understanding of the language and ideally he would have the curriculum to be able to follow on from.

is a private tutor and home schooling possible in spain?

we was more leaning towards keeping him in an English school with tutors whilst hes over with us.

Have you considered the 90 day rule that applies to non residents ??

I presume it applies to children ??

Yes we've considered this.

Me and my partner will be full residents with my son also, the 90 day rule only applies to non residents doesnt it? Even if the rule applies to him he'll be having 30days on/off so that abides by 90 days out of 180.

 If he is resident in UK and remains resident there then a private tutor here is fine and homeschooling what he is missing in the UK is ok. However the UK school would have to agree to this. 

If he is going to be a resident here then he has to be registered in the Spanish school system and you're back to square one. School is compulsory here from the age of 6. 

There are home schooling organisations in spain but its still quite a new concept and varies from region to region. Its a very grey area.I'd have a Google search and see if you can get in touch with one for some guidance.

Regarding your sons residency, because of the situation with joint custody I'd suggest some proper legal advice, I don't think its going to be that straightforward. 

Yes I totally agree 😊

The more research I've been doing into this the more and more I've read about keeping him in the UK school with having a private tutor and relaying it back and fourth with his school. As long as he's sticking it the set curriculum and meeting targets he should be fine. 

I'll be contacting and advisor in the next week to speak about the legal side of things and fingers crossed everything will be smooth sailing 

Apart from the legal and official side of things the stress and emotional strain on him would be huge for a 6 year old. As a teacher of over 40 years I know how children struggle to catch up after only a week or two away and to expect him to continue with the curriculum while at each other school is unrealistic. 

I think you would be putting his learning and his mental health at risk.

If a six year old is in Spain but not speaking Spanish his circle of friends will be limited. It would be a great pity if he was not bilingual.

Children need a stable environment. I think you better rethink time sharing arrangements for the child sake

He's got a Spanish teachers and is learning the language. I also think it would be a greater pity a child not seeing their parent, as I'm relocating for work. This way he gets to see both parents equally and both parents including my son agree on our arrangement. I wouldn't be doing this if I thought that this would harm my son in any way.
