The homestay evaluation procedure starts from inviting all homestay businesses the ones who had passed the evaluation but the validity has expired (3-year validity) and the ones who have never been evaluated before. Afterwards, the homestay owners have to submit the requested evaluation form to the inspectors including 2 central committees and 6 provincial committees. The inspectors then execute the evaluation by using the Ministry of Tourism and Sports evaluation form. Later on, the board evaluates and sets the score of each homestay to select the successful ones (up to 70%). Finally, the homestay is regarded and given the certification of passing the evaluation of Thai Homestay by the Ministry of Tourism and Sports.
