schools
Local schools, eg Saikung Primary, where they teach in both Cantonese and English medium are a good bet at present. They are looking to develop a multinational stream to complement the NETs. However, they will also interview and assess but with less constraint than the private sector. For P1 to P4, this can be a good start for a child to integrate into the HKG system with Cantonese fluency resulting fairly fast. That said, the ESF tend to put kids who go into the public system back to the end of the Q, (they will refute this though if formally consulted).
Various private schools are currently offering scholarships but these are highly competitive and do not cover years 1 to 4. HKG is very debenture biased and will react well to the larger debenture offering. Don't neglect the established local high end schools, St Pauls Boys Catholic School and St Margerets as an example.
