- !EAL/learning-support provision is not detailed publicly
- !Split-site logistics: Early Years sits at a separate Wong Chuk Hang centre from the main Aberdeen campus
- !No boarding — day school only
- !Top-of-market fees: HKD 175k–239k/yr tuition before boarding (+HKD 130.7k) and a HKD 60k/yr capital levy for non-debenture holders
- !Operated for-profit; has faced public scrutiny over large related-party payments to board-connected companies
- !No published verbatim BSO/ISI inspection rating — accreditation logos only, not a graded report
