Sarah's parents gave her a goal to clean the bathroom twice a month until the end of the year. which part of the smart criteria is missing from this goal?

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. 

Yeah we could do a lot more tomorrow
