THIS. Absolutely, this.
That’s why moments like that Back to School Night I described, where students from a decade-plus show up and I actually get to see and hear directly from them the impact I made years down the line, are so precious.
Sure, seeing test results is also good feedback, but it only shows the instruction aspect. How I’m affecting the student is not measureable. This is why I have my “Happy Box,” full of notes and letters and thank-yous from students over the years that I pull out and read when I feel drained and disheartened. Last year I received a few very kind letters from students who were very appreciative of my efforts to help them improve (as opposed to the grumbling resistance I often get from both parents and students when I’m pushing the kids forward, rather than letting them sit back in mediocre complacency or worse). One of them had an F with me first grading period–and a B by the end, because he worked his ass off and made use of my help. He, and another like him, progressed a full proficiency level on the state tests (several others improved, too–a couple by two levels–but it was satisfying seeing that I actually made a difference in a student who had been telling me all year long I was making a difference).
Regarding tenure:
Tenure is not meaning nearly as much right now. With budget slaughtering and pink slips everywhere, it isn’t going by the “last hired, first fired” thing. Most recent hires are in math and science, and those are sorely needed positions. We have a glut of elementary teachers, so that’s where the cuts were. (Hubby’s district has let something like 80 teachers go in the last 2 years.) In my district, it never thankfully got to that point (yet), but I was told those with elementary credentials who were hired in the last 5 years should all be sweating. Tenure would not save anyone.
