THAILAND - Thai children have fared better this year in the Programme for International Student Assessment (PISA), but are still below the international average.
By country, Thailand ranked 50th among the 65 nations participating in PISA 2012.
PISA, a triennial international survey, evaluates education systems worldwide by testing the skills and knowledge of 15-year-old students.
In PISA 2012, Thai children scored 444 in science, 441 in reading and 427 in mathematics.
The averages for PISA in those fields stood at 501, 496 and 494 respectively.
Education Minister Chaturon Chaisang, however, heralded the latest PISA results as an upward sign for Thai education's quality.
"There's a clear improvement," he said.
In PISA 2009and PISA 2009+ (the Programme for International Students Assessment), Thai students' average scores were 421 in reading, 425 in science and 419 in mathematics.
Thailand first joined the PISA in 2000. The Thai children's scores in PISA 2003 and PISA 2006, however, were lower than the scores from the first time. By PISA 2009, however, the drop in Thai children's scores had hit bottom.
Now, the 2012 PISA shows Thai children's scores are up.
The Institute for the Promotion of Teaching Science and Technology (IPST) said Thai students from demonstration schools and the Princess Chulabhorn's College schools had acquired good scores in the PISA 2012, reflecting that some Thai schools provided good quality education.
"This means we only have to extend such quality to all other schools," an IPST official said.
