Research by McKintosh, Frank, and  Spaulding (2010) and Predy, McIntosh, and Frank (2014) demonstrates that students who have  2 or  more Office Discipline  Referrals (ODRs) by October are on a trajectory to have 6 or more ODRs by the end of  the year. Catching these students early can break this cycle, and  get them the supports they need to have a successful school year. Consider using 2 ODRs by October as one decision rule for referring students  to your Tier 2 or Tier  3 team.
