Look at what a review actually describes. A trustworthy one names something concrete, like a particular teacher's approach or how the school handled a sick child. Reviews that only say the school is amazing or the best in Bali, with no detail, are worth less. Watch for a cluster of five star reviews posted within the same week or two, especially if the accounts posting them have no other reviews anywhere. That pattern often means a school asked parents, or paid someone, to post all at once rather than reviews building up naturally over time.
Cross check what you read against other sources before you trust it. Bali expat Facebook groups and WhatsApp parent chats tend to be more reliable than Google reviews, since people there are answering direct questions from other parents rather than leaving a public rating. Search the school's name alongside words like 'left' or 'switched' to find parents who moved their kids elsewhere, and read why. If a reviewer's profile has rated dozens of unrelated businesses in a short span, treat that review with more caution.
A handful of critical reviews mixed in with the positive ones is actually a good sign, since it shows the page hasn't been scrubbed. Pay attention to what the negative reviews mention, staff turnover or communication problems, since real issues tend to come up more than once. None of this replaces an in person visit, so ask to observe a class and talk with current parents at pickup. Ask if you can drop in unannounced for part of a morning: a school that says yes is usually the one whose reviews hold up.
