I am somewhat confused by/ concerned with the mastery index calculation. I am not understanding how giving credit for failing a test (up to .75) or extra credit for passing with an advanced score creates a more transparent system. Isn't the most transparent system a true pass rate? I don't see where just an overall pass rate will be available to the public. It seems like rather than making it transparent, it is just made less clear in a different manner than the current system (with growth included).
