Competency, Proficiency and Growth

The reading for Lindemann for Chapter 5 and Chapter 10 reminded me of the question Al Franken posed to Betsy DeVos at her Confirmation Hearing for Education Secretary on proficiency versus growth. In the book, Lindemann brings up the concept of competency versus proficiency for students attempting to improve their literacy. He states, competency is "the innate ability to make grammatical judgements" and proficiency is the "application of grammar rules' respectively" (80). The parallels between these two debates within education struck me as important, especially because the competency, proficiency and growth seem to overlap quite a lot. Although many educators attempt to remain apolitical, it's clear that these debates need to happen, both in and outside the classrooms. What are we shooting for: proficiency, growth, competency? How do the three find their place in the classroom in a happy mix?
