Kentville's teaching method is traditional with homeworks and tests. Learning materials are relatively harder compared to other kinders. Some ppl said the workload is 1.5x other kinders.
Alliance is activity-based with no tests. Kids are sure to have a happy school-life and stuffs taught are relatively easy. I was told during the interview they have 60 seats reserved for P1 but K3 have around 150 kids (every yr is different).
You should consider what is more suitable for your child and what method of teaching you prefer.
