If you have heard that SIS is the place to be in Shenzhen you've heard right.
I've lived in Shenzhen four years and became aware that SIS was the place to be early on and strived to get a position here after year one. The school is professional and genuine. The management is fair and honest, the housing and location is perfect. Shekou is the place to be in Shenzhen. The management are organised and take an active interest in teachers and their development. I'll say I haven't even been assisted in my development as a teacher as much in my career and I am very grateful to all faculty who assisted me in getting to this point.
I'll score 4.5's as I guess we could be paid more, I know there are other places out there that pay better but I mean, that is a minor minor strike in the minus column.
