Aoa brother, I'm living in UAE here most of the good standard schools have co education only low standard schools have separate for boys and girls I need to ask can I send my children's in co education or not

Yes. You can send your children to co education schools.

Coeducational schools are an excellent choice. I've always taught at co Ed schools and children have received a good education. What age is your child?

I believe, this may need to be in the Muslim area. I think the issue here is her religious teaching, that boys and girls can not be mixed.

If this is because of religious reasons, you should discuss it with your husband, who can then also discuss it with your local religious leader.

My sister lives in UAE and her children go to school there. Most schools there are coed.

Many of my teacher friends have gone there to teach and it is coed.

Some of the stricter sect groups do not allow co-ed of students. They also do not allow music classes for students.

In moderate groups, the physical education still must be not be co-ed but separate.

Canada and America are having issues in their schools with the large number of immigrants not wanting the mixed classes.

I know from your other question you have a young baby, so how many other children do you have and what are their ages? Also what does your husband think about the children education? Seems you can make whatever choice you want.
