They allowed 2 adults to enter. My husband was in business trip and couldnt attend. I brought my maid to look after my kid while the teacher was talking to me (English). The conversation mainly related to your expectation/educational path of your kid. The teacher also asked whether if my girl could eat on her own/potty training.
My girl liked the enviornment there and she sat properly throughout the 20 minutes conversation, finally she received an offer.
