@Octavia64 consider if it was car manufacturing. The government nationalises Land Rover - fine. It then bans all other cars from sale in the U.K. so that everyone has to use Land Rover - not fine and breaks any number of laws.
This comparison is utterly irrelevant.
The government's job is to provide a legal and regulatory framework. It is not to build cars.
However, it is the government's job to provide state education, to set the national curriculum and to oversee exam qualifications which are recognised nation-wide.
That's why I said that privatisation makes sense in some areas but not with exams.
Would it make sense to have multiple General Medical Councils, each with similar but slightly different rules and exams, and a government department to oversee that the various councils are similar enough? Of course not, it would be utterly bonkers!
the exam boards make a good living writing and selling qualifications that the U.K. has abandoned - o levels, IGcSEs (old style GCSEs) etc.
And they would be absolutely free to continue selling whatever services to whatever entities or governments want to buy those services from them
It seems to me that in this country we get to combine the worst of privatisation with the worst of state ownership
