How are spells in the Harry Potter universe made official

The actual invention of spells is not really important here, other than we know that they can be invented. After all, a bunch are mentioned in Half-Blood Prince that were invented by Snape in school.

Since this suggests that spells can be invented, it is reasonable that every one of them, from Wingardium Leviosa to Avada Kadavra, must have been invented at some time by someone.

So what is the difference between the above mentioned spells and something like Sectumsempra? Other than that one was written in the margin of a random textbook. What causes spells to become accepted as part of the charms canon, to the point where they are taught in Hogwarts in a decided year, suggesting that they have been investigated and their level of difficulty determined? Is there a department in the MoM that oversees this? Is it just done by smart people in ivory towers? And, if the former, what about spells used in other countries?
