Scoring the following categories: 

1. Mutual Respect and Consideration : Do both parties feel like their needs are being satisfied or does one party feel resentful over the other? Do teachers feel like working with parents is leaving them "pumped  and self- satisfied" or does it leave them "drained"?

2. Defining Success together: Do parents and teachers feel like they are getting the intended outcomes? Do they feel like they are working together toward a shared vision for success. 

3. Measure Necessity and Impact on students: "would eliminating this relationship between parents and teachers generate  negative consequences for students? Would our kids feel adrift without this collaboration?" The stronger the necessity, the higher the score

4. Replacements:  Would there be an opportunity to "re-allocate the resources invested in the parent-teacher relationship  to a more beneficial engagement?"  Is there a competing resource --perhaps  teacher- tutor or student -student relationships --how does this unique relationship soak up resources and are there other avenues to share those resources.
