For this first year we had a good experience. The communication via Edsby was clear and regular. Our son seemed to be challenged. He was encouraged to do Math enrichment and his teacher seemed to understand him well. Most of the feedback was given via Edsby and we largely left that up to our son. From a parent's perspective, we appreciated that there was a good balance of providing deadlines and expectations as well as problem solving where needed. We certainly felt we could contact teachers easily if needed, but we really never had much of a need (so far!).
I think the teaching is very engaging and easy to follow. When it isn't, it's easy to talk to the teachers and ask for an explanation. For example, I really dislike asking questions in class, and so if I have a question about a lesson or about an assignment it is very easy to ask teachers directly after class or later that day during lunch or a spare. I always clearly know what is expected from me as with every assignment comes a paper with the teachers marking rubric on it. I think the teachers know all their students fairly well since class sizes are smaller. Because of this, I feel as though they are able to know what success in the classroom looks like for each individual and don't have 1 standard for every single student.
