The next points are based on how you contribute to the school. Teachers who are +1s coach teams, they are on committees, they take on projects beyond the classroom. To be clear, I don’t think that everyone needs to do everything, but if everyone does something then the school is better for it. -1s are teachers who hurt the school’s atmosphere. They are negative towards new initiatives, they do not lead in a positive way or attend school events. They may also bring a negative reputation to the school.
If you are net positive you are likely an asset to your school. Teachers who are +2 are those that school leaders are likely to want to recruit and build around. Be mindful though that these are also the ones that can burn out quickly so be sure to set boundaries for yourself.
If you feel you are net negative then you may be unhappy or in need of a change. Perhaps you need an exciting new project, or partner with other teachers to either mentor or be mentored.
It’s important to note that you may find yourself evaluating yourself differently in different schools, in which case it may be a question of fit as opposed to overall capacity. There have been schools where I have been happier and as such, I was more engaged in those schools. Also, there have been times like when my children were born that I was less engaged in my current work because of the out of school priorities. That’s fine too! If you find yourself stagnant after a few years however, it might be time for some additional reflection.
As you might guess this is hardly a formal rating system, but rather a mental model in terms of self-evaluation. The primary focus will always be the classroom and the students in your care so rating both classroom and wider school as the same might be misleading. Again, this is always school and context dependent so do not be hard on yourself if you don’t like your self-evaluation, it may simply be a sign that you are ready for a change.
