M- Measurable
This goal is Specific: it tells Sarah what to do and how often, Assignable: Sarah knows it's her own responsibility, Realistic: This is an activity Sarah is capable of completing, and Time Related: Sarah knows she needs to do this twice a month for a year. There are no guidelines though, for how the cleaning will be measured. The M part of a SMART goal would tell her how to know when she has completely cleaned the bathroom to her parents' standards.
