Is this too obvious a solution?
In regard to recent reports on the relative weakness of Thai education, especially compared to Asean neighbours, if there is any genuine intent to improve matters, it might be a good start to appoint a minister who is actually qualified in the field. He or she should have a degree in education and preferably some experience in teaching.
It happens at the Ministry of Finance, doesn't it? They don't appoint car-washers or barbers to manage the nation's purse strings, so why do so in education? If this were approved, perhaps the minister would not be shuffled in regular Cabinet shakedowns but rather allowed to maintain the position beyond the average of ten months. What incentive is there for any minister to attempt improvements within such a short time, with such short-term priorities?
