Calculations for senior class rank used to lock after the first semester. Since the change in policy, now senior class rank locks after the fifth six weeks. This is a terrible idea because it really gives the class of 2020 the short end of the deal. The district recently changed the class rank system which is admitting the old system, which the class of 2020 is still using, is flawed but now the class is forced to deal with the flawed system for 12 weeks longer than the classes before them.
