I think KTS will choose parents with similar educational belief and perhaps full time mother has an advantage. But I think the interview of parents is also a critical part to decide acceptance. In my case, I'm a part-time mother but our performance in the interview seemed not so good, especially my husband.
There were only 2 teachers in my interview, one is Maths Panel ( a male teacher).... may be those met with 3 teachers have higher chance than the others????
I found the post in mid Dec last year, there will be 3 types of letter, acceptance/waiting/reject.... and there was only 1 page paper for acceptance..... so nervous ar!
