EXPAT FAMILIES · August 7, 2026
Jakarta and Bali host one of Southeast Asia's largest concentrations of international schools — British curriculum campuses, IB World Schools, and American-curriculum schools across South Jakarta, BSD, Kemang, Kuta, Canggu, and Sanur. If your child is enrolled in one of these, English-medium instruction is happening five days a week. But plenty of parents still notice a gap between how their child performs on school reading assessments and how confidently they actually pick up a book on their own. Here's why that gap opens up in an Indonesia-specific context, and what actually closes it.
Many international-school families in Jakarta and Bali run a genuinely multilingual household: Bahasa Indonesia (or a regional language like Javanese, Sundanese, or Balinese) at home and with extended family, English at school and often with a nanny or driver who code-switches, and sometimes a third language from an expat parent. This is a strength, not a deficit — but it does mean a child's English exposure can be concentrated almost entirely into school hours, roughly 6-7 hours a day, five days a week, with very little English input after 3pm.
Compare that to a child in an English-speaking country who hears and reads English all evening, at the dinner table, in bedtime stories, on weekend errands. The Jakarta or Bali international-school child isn't behind in ability — they simply get far less unstructured English reading practice outside school. Independent reading fluency, the kind where a child chooses a book for fun rather than completes an assigned reading log, is the piece that tends to lag.
A second, quieter issue: families relocate frequently in the expat circuit, and Jakarta/Bali schools run British (Cambridge/National Curriculum), IB PYP, and American systems side by side — sometimes within the same family across siblings or across a move. Reading levels aren't standardized across these systems the way math is. A child who was a strong reader by their old school's benchmark can look "behind" after switching curricula, purely because of how each system labels reading stages, not because their actual decoding or comprehension skill dropped. If your child's reported reading level suddenly shifted after a school change, check whether it's a real skill gap or just a different labeling scale before reacting.
In a multilingual household, the goal isn't more hours in English overall — it's making sure some of those hours involve actually reading, not just hearing the language spoken at school.
Class Readers is an ad-free iOS app built for exactly this gap: original storybooks across 12 reading levels with word-by-word karaoke narration, so a child gets consistent, correctly-modeled English sound-to-print practice even when no native English speaker is available at home that evening. Built-in recording lets kids practice reading aloud and hear themselves back, and short quizzes after each story help you and the school track real comprehension, not just curriculum labels. A free book is included to try; Premium unlocks the full library across all 12 levels.

No — this is the normal pattern for international-school households here. The thing to watch is total English reading input after school hours, not which language your family speaks at home.
It gives kids 12 levels of narrated storybooks, recording, and quizzes for consistent English reading practice at home, even without a native English speaker available every evening. A free book is included.
