here are some points about MC & AA, from an insiders point of view:
* academic, they seem to be of equal footing.

*both schools are PAASCU accredited. Miriam is level 3!
* Miriam is a much bigger school, in terms of population per level. MC is about 10 class per level, AA has 4-5. Students per class is the same.
*teacher's background and competency is just about the same.
*AA is run by nuns, while MC is run by lay. Both are Catholic schools, but AA is more heavy on religious practices since they are instilling the virtues of Mary and the teachings of Mary Eugene, the founder of the Assumption sisters.
*Both schools are Green schools, meaning their advoacy is with the environment.
*Both develop academically competent kids, especially in their communication.
* Both have very good parent groups.
*classroom wise, both are non air conditioned, as they value the environment. thats why both have big trees and wide spaces.
* kids wise, i observe the AA girls to be simpler.

* both have very good socio-emotional programs - homeroom and guidance. teachers and counselors are very hands on.
* AA has more intensive sessions for student enrichment, meaning speacial talks on self development, especially their sexuality programs from Gr. 7 to HS. I see this as commitment to raise girls in the Assumption values.
* MC does well in research, which is important for their continues program development. they are heavy in establishing linkages, both here and abroad. they regularly benchmark with other schools to see how well they are doing
* MC has a very good library and viewing room facilities, most classrooms have LCD projectors already.

i can list a whole lot more... but my question is: WHAT IS YOUR TOP MOST VALUE AS A PARENT?
is it the school's academic program? is it the distance? is it their holistic development approach? is it their religious upbringing/values? Is it the school environment? or how your child would fit and thrive in that school?
From what is important for you, then you can decide. Its not just about the school, its more on what you value. Schools have different values, mission and vision. IMO, we choose the school base on what will fit our child's needs and what we believe in our family

Hope this helps!
