Here are some suggestions:

The girls once enrolled must wear a special uniform, which could consist of stockings, very short pleated skirts, a corset and of course a collar, which will have a leash attached.

Lessons could include having to suck the cocks of 5 men, the girls must make all 5 men cum or they must repeat the course. They will be taught to worship the cock.

They will also learn the positions, how to offer your pussy to your Master, how to behave, the correct ettiquette and to accept spanking and humiliation (for example being spanked in front of the other girls).

They will also be taught how to fuck and be fucked by a female. The girls will be paired and then eat each others pussies, fuck each other's cunts and assholes. Each girl must do this with every other girl in her "year".

They will perform scenarios in which they are offered to numerous men as a fucktoy, and will learn the correct behaviour when pleasing many men.

Before the course starts, they will be taken to the Gyno Lab where their sexual receptiveness and sensitivity will be teested (such as how many times they will come on a vibrator, sybian etc)and graded using a wide variety of devices. These thorough examinations will be carried out by a female Doctor who will then report to the Headmaster.
