South Korea's adults' ”verbal ability, mathematical ability, and problem-solving ability” are ”below” the OECD average

It was found that South Korean adults' verbal ability, mathematical ability, and adaptive problem-solving skills are all below the OECD (Organization for Economic Cooperation and Development) average.
However, the younger you are, the more your abilities improve, and the more likely it is that you will be able to find a job with a higher level of academic ability than is required for that job.
The OECD released the results of its Programme for International Adult Skills (PIAAC) at 7 a.m. on the 10th.
The average scores for Korean adults were 249 for verbal ability, 253 for mathematical ability, and 238 for adaptive problem-solving.
Meanwhile, the OECD average was 260 points for verbal ability, 263 points for mathematics, and 251 points for adaptive problem-solving, with South Korea's scores lower in all areas.
