Miscellaneous Committees etc.
for which we don't know the department
Wizarding Examinations Authority
Personnel: headed by Griselda Marchbanks, includes Professor Tofty
Not sure if this is actually a Ministry organization, but since the Ministry clearly holds authority over Hogwarts it seems likely that this body is part of the Ministry of Magic. They administer the O.W.L. and N.E.W.T exams for students which are given in June every year. Members travel to Hogwarts and test individual students for the practical examinations. The theory portion of the O.W.L. test is proctored by Hogwarts staff members (Flitwick administered the Defence Against the Dark Arts exam twenty years ago, while McGonagall proctored the Charms O.W.L. for Harry's class). (JKR, OP15, 31).
Responsible for hiding the giant Kelpie in Loch Ness from Muggle eyes (DP).
