In Thailand, there are challenges to achieving an education. Over 2 million children are not educated (28% of all children) and about 1.8 million students (aged 6-14 years old) in the education system are underprivileged (https://isee.eef.or.th/national3/index.html
, ISEE, 2019). Moreover, showing from the PISA scores (PISA 2018), Thai student scores are ranking at the bottom for all Math, Science and Reading which reflects severe poor quality in Thailand’s education system, and that also leads to other societal problems. Despite massive attention by the government, education quality still has not improved, as indicated by the low average score on the national examinations in recent years. In addition, the inadequacy of quality teachers is also one of the major problems. This causes the tremendously high student-teacher ratio, and there are a large number of teachers teaching subjects which they are not qualified. In addition, Thailand was ranked among the lowest of the participated countries in the equity in educational resources (PISA 2018).
