Provate Education for Children

I am looking for a list of Private Schools providing quality education in Riyadh. I need a mix of American System and British System Schools, I found a lot of them online but it is reaaly difficult to assess the quality of education. Since I will be moving from Canada to KSA, my kids are used to American System specially the older kids. Ages of my children are 14, 12, & 5. Thanks in Advance.

American International School Riyadh     aisr.org
British International School Riyadh     bisr.com.sa

Multinational school -Australian Victorian Curriculum -  though someone said not past grade 5
French school

Above 4 schools all northern Riyadh near international/domestic airport
Nearest compounds thatvi know of:. al hamra, Cordoba, Arizona, al nakhla, Fal, California (yet to open), al reem, al bustan

American School is connected to Al Bustan compound. I think British school is on Al hamra but not 100%

If you google American schools in Riyadh top of the list is the website for American school. Although school breaks for summer this until mid August, I was told just to e mail the registration forms, good luck in your search
