First of all, there is a great difference between the recruitment conditions of schools and the standards of political examination of recruitment. Being qualified at the time of conscription does not necessarily guarantee being qualified at the political examination of conscription. Article 5 is actually a trap. If a soldier couldn't leave at that time, the school would have no responsibility at all, and students could only suffer dumb losses.
Second, even if the medical examination and political examination are qualified, schools that cannot serve as soldiers have no right to decide. It should be decided by the local people's armed forces department. The school is not the recruitment authority, and its enlistment agreement is not guaranteed, unless the school and the local armed forces are behind the scenes, but in that case, once someone reports and verifies it, the local armed forces will also be unlucky. General army leaders dare not do so.
Third, after joining the army, the jobs of recruits are not determined until the army, and even the district and county armed forces departments can't decide, let alone the school. Every year, a place recruits different troops. Even if the school has great local skills, it is impossible to extend it to all troops, let alone re-elect non-commissioned officers (let alone the second phase).
To be sure, the tuition fees of such schools are definitely much higher than the normal fees. Don't believe it, I promise whoever believes it will be unlucky.
