How to You Measure the Worth of a Teacher?

How do you measure the worth of a teacher - in test scores, in graduates, in invitations, in stacks of papers?

I have always worked to be a teacher that created community and relationships within the classroom. My favorite way to do that is through class read alouds. Magic happens as we gather together to take a journey with the characters in the book. Through the book we address language arts skills as well as social emotional learning in an authentic way. 

The emphasis on high-stakes testing has decreased the time I previously allocated to read alouds and independent reading time. While I have tried to find ways to include read alouds into my reading instruction, I have been met with resistance for not spending more time on testing aligned lessons. So I wonder, how do you measure the worth of a teacher. 

Is a teacher's legacy academic performance or something else? When students talk to me about their memories, they always point out one particular read aloud that stuck with them. It is those texts that leave an impact on my students. Parents tell me their children were never really readers until the year the spent with me. Creating readers is impact that makes me most proud because readers are learners. There's no doubt that test aligned instruction creates higher test performance, but does it create readers and learners.
