C/Sing of Academy students is routinely done by D of Ts (or Course Supervisors) except where the student is auditing for the HGC. Then the regular org C/S handles the C/Sing of the students' sessions.
The D of T has internes or qualified students assist him only as he selects — based on their degree of skill — but the responsibility for the quality of C/Sing remains with the D of T.
This should be fairly easy to do as it is expected that the student will have any needful progress and advance programs up to that level in the HGC (or lower courses for prior advance pgm steps.)
The Academy does not specialize in lengthy progress pgms not even in advance pgms except for the grade run by Auditors of the Classification Level being taught. Students should primarily recieve auditing on that expanded grade or possibly a brief life repair.
The C/S in the Academy would routinely only direct the next process of the grade or that a swift repair of a goofed session be done. (The required "24 hour rule" repair to be done by a student wherever possible.)
Where a Dianetic student needs a Review it is done by Academy Scientology students.
Anyone C/Sing must be fully familiar with the C/S Series HCOBs.
