If you are using the most recent score for your standards calculation, the BOY assessment scores will not affect the student mastery because the student most likely has taken several more assessments to override those scores because of the most recent.
If you are using an average calculation, it will pull in the BOY scores, so you would need to consider, exporting those scores and then removing the assessment from the tracker to recalculate the mastery level or change your calculation to most recent.
