Heritage International School, Phnom Penh

Online reviews are limited but lean positive on teaching and friendliness.
Parents and former students consistently praise the teachers and the push to use English.
One ex-student called the summer school programme "the best" for its extra recess and flexible dress.
The Christian, Canadian-style ethos and qualified staff get repeat mentions.
A former student noted that some parts of the building were "quite dirty" and that early drop-off (7am) is discouraged because young children would be unsupervised.
