There are many private international schools in Dubai catering specifically to the large foreign community that calls the emirate home, and expats generally choose this option over the emirate's public schools.
For the most part, schools in Dubai adhere to high standards, but can have very different approaches. Expats must consider what kind of learning environment will best benefit their child and what priorities they have in choosing an institution. That said, many private schools in Dubai offer a brand of education that allows students to enter any university in the world.
The Dubai Schools Inspection Bureau publishes annual reviews of all private schools in Dubai, and reports published on its website are a good place to get objective information about schools.
