I want to know the answer to the following question:
Who awarded a teaching license in Islamic schools?
All the background I'm provided with is that "A significant difference between the ijāzat al-tadrīs and the licentia docendi was that the former was awarded by the individual scholar-teacher, while the latter was awarded by the chief official of the university, who represented the collective faculty, rather than the individual scholar-teacher.". Is that enough to answer the question?
Answer: yes
