12 Princess Chulabhorn Science High Schools

Twelve Princess Chulabhorn Science High Schools (PCSHS) were established in honor of Her Royal Highness Princess Chulabhorn to commemorate her 36th birthday in 1993. Prof. Dr. Her Royal Highness Princess Chulabhorn is the youngest daughter of His Late Majesty King Bhumibol Adulyadej and Queen Sirikit of Thailand.

She has been an instructor in Chemistry at Mahidol University since 1985. She is also a member of the President’s Council of the University of Tokyo.

Being Thailand’s leading Super Science High Schools around the country, only students with outstanding academic achievements in Mathematics and Science are selected to study at PCSHS. Not only do they utilize specialized and intensive curricula in mathematics and science emphasizing on research activities, but also they have developed academic cooperation with twelve Super Science High Schools (SSHs) in Japan. The cooperation has included online communication and students/teachers exchange, which led to collaborative researches.

The TJ-SSF 2023 will take a big step towards the collaborative learning and teaching, and thus building closer and stronger collaboration in gifted education in Mathematics ,Science and Technology between the two countries.

Super Science High Schools

Super Science High Schools (SSH Schools) are senior high schools that prioritize Science, Technology and Mathematics and in so doing these schools will receive the SSH designation awarded by the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT). The program was launched as part of its “Science Literacy Enhancement Initiatives”

SSH schools with this status receive increased funding and are encouraged to develop links with universities and other academic institutions. Selected high schools are expected to develop curricula based on Science and Mathematics in cooperation with universities or research institutes.
