Class remains disorderly (7)

I believe the answer is:

seminar

'class' is the definition.
(seminar is a kind of class)

'remains disorderly' is the wordplay.
'disorderly' is an anagram indicator.
'remains' with letters rearranged gives 'SEMINAR'.

(Other definitions for seminar that I've seen before include "Group discussing" , "University discussion" , "workshop" , "Academic class" , "Teaching meeting, conference" .)

I've seen this clue in The Times.
