Over basic education (grades 1-12), Thai language provides a tool for seeking knowledge and experiences from various sources of data and information in order to acquire knowledge and engage in processes of analytical, critical and creative thinking, so as to be attuned to social change and scientific and technological progress. It also serves the useful purpose of occupational development for achieving economic security. Furthermore, it is the medium of expression of our ancestors’ wisdom regarding culture, tradition and aesthetics, representing a treasure of the highest value, worthy of learning, conserving and transmitting to succeeding generations as a permanent feature of the Thai nation.
