I glanced through the list and spotted some typos:

e.g การรับรองวิทยฐานะ = accreditation (a 't' is missing)

นักเรียนทุน = scholarship student (listed above as 'scholar' = ผู้เรียนรู้)

โรงเรียนการศึกษาผู้ใหญ่ภาคค่ำ = adult night school (listed above as 'opportunity school' -- see also a few rows later the same opportunity school is used for 'special school' -- for children with special needs).

Perhaps, we should 'clean up' the list first to stop 'spreading mistakes'. ;-)

Can you help?
