Does anyone know what is the number of students that determines if that school plays either Class A or Class AA hockey? Also, does an all boy or girl school's student body double when determining their class? If an all girls school had 600 students, would the MHSL double that to 1,200 when determing their class?

It changes.

The biggest 64 schools are automatically AA and the rest have the option to opt up. This year the cutoff was 1359.

And yes, schools like STA have their attendance doubled when deciding what class they fall in.
