We can...
examine and think about an important question; who controls all the items  a teacher is  using in their classroom?

Teachers, as time moves on through your teaching career you will improve your classroom teaching skills  by buying things like books, scientific instruments, math manipulatives, and computer equipment.

These things are important to you because they help students learn. This becomes an important part of your teaching experience.

The above photo was the   60cm TV/Monitor I used in my classroom. That TV was  important to me because I could show Bill Nye the Science Guy or Mathmaker videos any time I wanted. I didn’t have to go down to the AV room and wheel a TV into my room.

But as time moves on, this can happen to you as a teacher. Unfortunately, because of school closings, declining enrollment, or the natural movement within your school, you find out that you are going to be moved to a new classroom or school.

Will you be able to take all the tools, materials and organizational items that you have accumulated in your present classroom to your new classroom or school?

Who has control of these items?

Before purchasing any item, have you discussed this possible situation with your federation, principal, or school board. 

Have you clarified with your federation, principal and your board, that the items you purchased with their funds, should follow you to your next classroom.

If you are moved will the school board make arrangements to help move you?

Teachers are always willing to go on to a new assignment as long as their previous efforts and experience go with them.

Some boards of education are more understanding than others.

Being motivated as a teacher is very important. Before putting a lot of work into planning and effort into purchasing tools and materials for you to complete your plan, thoroughly discuss professional ownership considerations with your federation, your principal and your school board.

After discussions, a written agreement would be wise so that all parties understand what their positions and responsibilities are. Clarity will save you a lot of anxiety.
