Thailand's English proficiency is on the decline for the third consecutive year, according to a global survey conducted by Education First. The survey, which was announced in November last year, ranked 112 countries that don't use English as their official language in order of their English Proficiency Index. Thailand is No.100, being the lowest ranking country in Southeast Asia. In 2020, we were at 89 and in 2019, we were at 74. Not so promising.
