It is important to ask what is a quality education? Once that is defined you can then ask is Alberta providing quality education.
I asked Google AI to Define a quality primary school education environment. That way it is unbiased.
Physical Space
Comfort: Good lighting, ventilation, and ergonomic furniture.
Health: Clean water, private toilets, and hygiene facilities.
Safety: Sturdy buildings, fire exits, and secure perimeters.
Activity: Safe playgrounds and green spaces for movement.
Social & Emotional Climate
Safety: Zero tolerance for bullying or corporal punishment.
Inclusion: Accessibility for all abilities and cultural backgrounds.
Support: Small class sizes and positive teacher-student bonds.
Resources: Easy access to books, technology, and art supplies.
While a lot of the physical space items are met, I do know of a couple areas where we're falling short. For example there is a situation where to save money multiple schools share one custodian. When a student puked in the classroom, the class needed to be relocated for over an hour while waiting for the custodian come to the school and cleaned up the puke. There is also no AC or windows that can open in this school so when it gets hot outside there is no relief beyond drinking cold water. I think the city has also said there are a lot of playgrounds nearing their end of life. This isn't all buildings but we're a first world country so there should be zero tolerance for us not to meet the physical space needs of students.
Most of the social and emotional climate items are met but there are some areas that need to improve. Some might actually say we're too inclusive in some ways, having students with complex ability needs integrated with everyone can be good for socialization but bad for other students that can witness outbursts and may not receive the attention they need because the complex ability student requires more attention. The teacher to student ratio has not been corrected to where it needs to be. Class sizes have been well documented, while those are receiving more attention, years of underfunding has left a deficit. So while funding has improved, the affects of underfunding won't work their way out of the system for years.
So, sure if you look at the numbers today things look good but you cannot look at those numbers in a vacuum.
